1. Introduction

The genus Ficusbelongs to Moraceae(Mulberry family). It is comprised of around 1000 species from pantropica land subtropical origins [1]. Plants of the family are on the whole woody, ranging from trees and shrubs to climbers [2]. Ficus benghalensisis an evergreen tree with a wide, spreading crown; it can grow 20–30 m or more tall. The plant usually begins life as an epiphyte, growing in the branch of another tree; as it grows older it sends down aerial roots which, when root reach the ground become much thicker and more vigorous. They supply nutrients to the fig, allowing it to grow faster than the host tree. Finally, the host dies, leaving the fig to carry on growing without competition. It can become a huge, spreading tree in time, with some specimens several hundred meters across and producing aerial roots from the spreading branches that in the long run become new trunks and enable the crown to spread considerably further.

F. benghalensishas many common names as Indian banyan tree, East Indian fig tree, and vada tree [2, 3]. Its name has been derived from the Hindu traders, called banyans, who favored the tree [2]. Banyan tree is considered sacred by Hindus and is largely grown near temples. It is a large and extensive growing tree of the Indian subcontinent. The wood is grey, moderately hard and durable under water. The wood of the “props” is stronger than that of the main trunk. The timber is used for making well-curbs, furniture, crates, door panels and cart-shafts. The props are used for tent poles and umbrella handles. The leaves are used as fodder for cattle and elephants.

The tree is harvested from the wild for its edible fruit and medicinal uses. The tree is considered sacred by Hindus and is commonly planted for religious purposes; it is also grown as an ornamental and to provide shade along roads as well as in parks and large gardens.

Ficuscompound showed significant antioxidant effect, which might be ascribed to their polyphenolic nature. The stem bark of Ficus benghalensisL. and Ficus racemosaL. are utilized in India for the treatment of diabetes and various different illnesses. The bark of Ficus benghalensisdecreased fasting blood sugar and glycosylated hemoglobin. The fruit of Ficus benghalensisis used in folk medicine for respiratory disorders and certain skin disease.

According to Edlin and Nimmo [4] proved that the latex (source of rubber) has been found in large quantity in the wood of Ficusgenus, which is representing one of the largest economical uses of Ficusin Egypt. Ficus benghalensisis thought to be cultivated 150 years ago in Ismailia during the process of digging the Suez Canal back in 1859–1869.

These days, Ficus trees are subjected to many threats affecting the presence of main populations. These threats comprised by the following points: (a) human cutting for general purposes, (b) cutting by council city for shifting landscape of the city, and (c) absence of a specific pollinating wasp in order to reproduce and spread [5]. For these reasons and subsequently results, it is very hard to find a new tree individuals coming up to these areas of Ficus. These threats will change the landscape of the whole area in the next few years.

The present study is aimed to anticipate a strategic conservation plan for landscape construction primed by Ficustrees in Ismailia, Egypt and discuss the age structure of this species.


2. Distribution

Ficus benghalensisis native to South Asia particularly India, Sri Lanka and Pakistan (Figure 1). It is often planted around temples and a place of religious interest. It is considered as sacred tree by both Hindus and Buddhists.

Figure 1.

Distribution ofFicus benghalensisin South Asia according to

Banyan tree is widely cultivated in city parks and botanical gardens throughout the New World and Old World tropics. It grows well in tropical, semi-tropical areas, monsoon and rain forests with moderate to ample rainfall. Humid air and moist soil and is hardy, drought resistance and withstands mild frost is well suited for its growth [6].

Ismailia governorate is located in the eastern part of Egypt at the middle part of Suez Canal. It is bounded from the East by Suez Canal (that penetrates Temsah Lake and Bitter Lakes), from the West by the eastern borders of Delta along Damietta Nile branch, from the South by Suez-Cairo high way, Port Said and Manzala Lake from the North (Figure 2). It was established as a separate governorate by the declaration law number 24 in 1960. Its area is 5067 km2 and has seven main cities, Ismailia (the capital), Fayed, El-Tal El-Kber, El-Kantara east, El-Kantara west, El-Ksasen and Abo Souer. Human population of Ismailia governorate reaches 1.4 million individuals.

3. Description

F. benghalensis, frequently very large, up to 30 m length, have numerous aerial roots which can extend into new trunks so that the tree goes on thinning out laterally indefinitely; a single tree can thus cover a very wide area. The leaves are leathery, entire, ovate or elliptic, 20–40 cm long with prominent lateral veins. The figs are 1–2 cm in diameter, without stalks, in pairs in leaf axils, and when ripe are bright red.

Leaves are glossy, leathery and glabrous when mature, approximate hear the end of branches, ovate, mostly obtuse, base cordate or rounded, thickly coriaceous, basal nerves 3–7, the midrib with 4–6 pairs of secondary nerves, blade 10–20 cm, petiole 2–5 cm long, shoot pubescent, 1.5–2 cm in diameter, sessile, scarlet, red once ripe [7].

A flower has very small, separate, male and female flowers. The male flowers crowded near the mouth of the receptacle, whereas female flowers with shorter perianth, style long, male and female in the same receptacle [8].

Fruits are globular, sessile in axillary pairs, fleshy pericarp and with achenesen trenched in them, they are dark red in color, 1.5–2.0 cm diameter, red to dark purple when ripe; seeds are tiny. Fruit is not edible for humans but is eaten by birds and monkeys [8].


4. Ecology

In Egypt, various Ficusspecies are establish in streets, gardens, parks and outside the canal banks. Two of the most favorable fruits are eaten by Egyptian people (F. caricaand F. sycomorus) and also they use Ficusin their traditional uses in folk medicine respiratory disorders and certain skin diseases [9, 10].

Mousa et al. [9, 10] detailed that there are about 20 species of Ficusnative to Egypt; most of them are cultivated as street trees for providing shade (e.g., F. retusa) as in Alexandria city, while other species used as ornamental plants (e.g., F. religiosa). Edlin and Nimmo [4] proved that the latex (source of rubber) has been found in large quantity in the wood of Ficusgenus, which is representing one of the largest economical uses of Ficusin Egypt.


5. Field visits and sampling

Four main localities characterized by large number of F. benghalensis, trees were selected in Ismailia city for the present study. These localities are: El-Mawany area comprises of 55 trees, Mohamed Ali area comprises of 5 trees, Amon area comprises of 16 trees, and Nemra Ceta comprise of 38 trees (Figures 3 and 4). In each locality, number of vegetation parameters was measured to describe the Ficustrees including; height, cover, circumference at base (CAB), circumference at breast height (CBH), number of aerial root and vitality. Tree vitality has also been measured using the visual assessment of crown conditions. Tree condition is often used in conjunction with other vitality assessments for verification purposes [11, 12]. However, vitality was measured according to the following scale: high, excellent healthy plant (vigor); medium, normal or some yellow leaflets and low, not healthy with yellow leaves [13].

6. Soil analysis

In each site, three soil samples (0–20 cm depth) were taken for soil chemical and physical analyses. Particle size analysis was done by dry sieving for the coarse sand and by pipette for fine sand, slit, and clay [14]. Soil aggregation was treated by 5% of sodium hexametaphosphate as a dispersing agent. Soil was classified based on the percentage of clay and sand using USDA limits of the basic soil textural classes [15]. Soil pH was measured electrometrically using pH meter model 1671 in soil suspension of ratio 1:2.5 soil to water. The soil-water mixture was first shacked for 2 hours, and then pH was measured [16].

The EC was measured in the soil water extract 1:1 using electrical conductivity meter model 4310 ENAWY [17]. Reported the degree of salinity for the course to loamy sand (1:1 soil water extract) as follows: 0.1–1 ds\m for non-saline, and 1.2–2.4 ds\m for slightly saline, 2.5–4.4 ds\m for modestly saline and 4.5–8.9 ds/m for strongly saline. Soil organic matter influences many soil properties including (i) the capacity of soil to supply, N, P and S and trace metals to plant’s, (ii) infiltration and retention of water, (iii) degree of aggregation and overall structure that affect air and water relationships, (iv) cation exchange capacity, (v) soil color, which in turn affects temperature relationships [18]. Soil organic matter was measured using loss-on ignition (LOI) method carried out at a high temperature. This method gives quantitative oxidation of organic matter [18].


7. Age dating

Age dating of Ficustrees was assessed by counting the annual rings and measuring the circumference of the branches. To avoid destruction of Ficustrees, the counting procedure was applied to the already cut branches in each site. Annual rings and circumference of the available 21 cross sections of Ficustrees were measured. Simple regression between annual rings as dependent variable and circumference as independent variable was carried out to have the regression equation that used to figure out the age dating of the main trunk of F. benghalensistrees.

To describe the age dating structure of Ficustrees at different sites, scale as follows: <150, 151–200, 201–250, 251–300, 301–350, and >350 years (Table 1).

8. Data treatment

Data were statistically analyzed [19] using SPSS software (statistical package for social sciences, version 8). One-way ANOVA was carried out to test the variation of different variables between different four sites. Linear correlation coefficient, r, was estimated to find out the relationships between age dating, height and tree cover.


9. Results

9.1 Vegetation parameters

The maximum tree height was 12.5 m recorded at site four (Nemra Ceta) while the minimum tree height was 1.70 m recorded at site two (Mohamed Ali). The circumference at base (CAB) ranged between 0.56 and 1.9 m found at Nemra Ceta, while the highest circumference at breast height (CBH) was 1.8 m and lowest value of 0.65 m, both found at site one (El Mawany). The crown cover of trees ranged between 3.70 and 268.67 m2, whereas the highest value was found at site three (Amon area) and the lowest value at site four (Nemra Ceta) (Table 2). The number of aerial roots that were recognized in the studied sites fluctuated from 1 to 183 roots. Mean values of four localities are shown in (Table 3).

As appeared (Table 4) summarizing the soil properties of the four sites studied, site one (El Mawany) has the lowest EC (4.52 ds/m) whereas site two (Mohamed Ali) shows the highest EC (7.84 ds\m) and both EC values of sites three (Amon) and four (Nemra Ceta) were (4.56 ds\m) and (5.47 ds\m) respectively. Site four (Nemra Ceta) shows the highest content of organic matter (7.80%) whereas site one (El Mawany) show the lowest content (4.18%), while results for sites three (Amon) and two (Mohamed Ali) were 7.30 and 6.60%, respectively. Site one (El Mawany) shows the lowest content of sand was 89.33% whereas moderate content of clay 5% and highest content of silt 5.67%. Site three (Amon) shows highest content of sand 92.67% whereas the lowest silt content and clay 3.67%. Site four (Nemra Ceta) shows the highest content of clay 5.33% whereas moderate content of fine sand fraction 91% and lowest content of silt 3.67%.

9.3 Age dating

Diameter and annual rings of each branch were measured and regression equation was calculated using the data of diameter and number of growth rings in order to figure out the age dating of the main trunk of different Ficustrees. The regression equation is:

No. of rings = (−0.933 + 2.195 circumference) (cm) (Figure 5).

Age dating at El Mawany, ranged from 142 to 394 years. The oldest tree is 394 years, 10.51 m height and 106.73 m2 cover while the youngest tress is 142 years, 3.52 m height and 20.58 m2 cover. At site two (Mohamad Ali) which has 16 trees age dating of these trees ranges from 175 to 295 years, the oldest tree is 295 years, 7.50 m height and 59.42 m2 cover, and whereas the youngest tree is 1.70 m height and 80.32 m2 cover. Whereas site three (Amon) includes five trees, age of these trees range from 240 to 344 years, the oldest tree is 344 years, 10.50 m height and 268.67 m2 cover; whereas the youngest tree which is 240 years old, 10 m height and 224.20 m2 cover. Site four (Nemra Ceta) which has 38 trees, age of these trees ranges from 96 to 357 years, the oldest tree which is 357 years, 8 m height and 124.82 m2 cover, whereas the youngest tree is 126 years, 5 m height and 13.72 m2 cover.

Based on the regression results, the oldest Ficustree is 394 years found at site one (El Mawany), followed by the second oldest tree about 357 years found at site four (Nemra Ceta).

9.4 Relationships between age and vegetation parameters

One way ANOVA (analysis of variance) of height, CAB, CBH, cover, and age have significant variation between the different sites. Multiple comparison of the significant variables using Duncan test showed that site three has the highest mean values of different parameters (height = 10.1, CBH = 138.9 m, cover = 229.8 m2, and age = 304 years), followed by site number one and four. On the other hand, site number two showed the lowest mean values of these parameters (CBH = 9.8 m and cover = 51.6 m2) (Table 3). Analyses of variance of vegetation parameters and age for F. benghalensisin the four studies area are shown in (Table 5).

10. Discussion

F. benghalensisis the world’s largest tree as far as its spread [20]. The tree is native to India and Pakistan (it is named for Benghal). It is a popular shade-tree, cultivated in many tropical countries [21]. The plant begins growth on other trees and eventually envelopes them completely. Aerial roots hang down from the branches and these eventually become trunks. This circle of trunks deriving from one original tree can reach an enormous size—200 m in diameter and 30 m in height. Their shade has made them important gathering places. Known in Hindu mythology as “the wish-fulfilling tree,” banyans represent eternal life. The tree is sacred to Hindus and Buddhists in India and is frequently planted around temples. Being a majestic ornamental tree it is also planted in parks and along streets in the tropics. In temperate climates it is grown as an indoor plant. In general, the banyan is a source of dye and shellac—an important component in French polish—produced by lac insects which inhabit the tree as pests.

The present study showed that populations of Ficus benghalensishave limited distribution in Ismailia city (target study area). Four sites were only recognized in the study area. The limitation may return to the requirements of the pollinating wasp (Eupristina masoni). However, Ismailia is located near the midpoint of the Suez Canal, on the northwestern shore of Lake Temsaḥ. The lake, is a natural depression, was connected to the Gulf of Suez of the Red Sea in pharaonic times. The city was founded in 1863 by the French engineer Ferdinand de Lesseps, constructor of the Suez Canal, as a base camp. It was named for the ruling Egyptian khedive (viceroy) Ismail Pasha, whose elaborate palace built for the gala opening of the canal in 1869 has fallen into ruin. Laid out in the nineteenth century style, with broad avenues, tree-lined squares, parks, and gardens, it has a gridiron street plan. Ismailia was cultivated with huge number of F. benghalensisand now is subjected to huge human threats affecting the presence of these trees.

Nadel et al. [10] described the pollination process which is the main reason of not producing off spring of F. benghalensis. In general, the genus Ficus(Moraceae) is distributed in the tropics and subtropics worldwide. About one-half of the species are monoecious, the rest being gynodioecious but functionally dioecious Nadel et al. [10]. Most species grow as trees, while others are shrubs or climber. Frequently, germination in many species occurs on other trees, with the seedlings growing epiphytically while sending a set of connections of roots down to the soil, eventually “strangling” their nurse trees [10]. However, other species begin their lives on rocks or straight in soil. Pantropical in distribution, only a few fig species extend into warm temperate regions.

As expressed by Nadel et al. [10], with few exceptions, each fig species is pollinated by a different species of wasp in the family Agaonidae(Hymenoptera: Chacidoidea) [5, 22, 23, 24]. The pollination biology of monoecious species has been described by Galil and Eisikowitch [25, 26]. A pollen-laden female wasp enters the syconium or “fig,” an urn-shaped inflorescence which, when in the receptive stage, is lined internally with dozens or hundreds of receptive female flowers and a few immature male flowers. The wasp lays her eggs through the styles into some of the ovaries, pollinating most of the flowers in the process. In dioecious fig species, pollination is more complex. The “male” tree is monoecious, having both male and female flowers in each syconium, but it has only short-styled female flowers. Nearly all of these female flowers are used by the ovipositing wasps, with the result that the tree produces no seeds, only pollen and agaonids. The female tree, on the other hand, is truly female; the syconia contain only female flowers. These flowers are all long-styled, which effectively eliminates the ability of the agaonid to oviposit in them. The absences of this process of pollination cause failure in germination of F. benghalensis.

Age dating results of Ficus benghalensisreflect the history of Ismailia area, which return to the age of Suez Canal. Digging of Suez Canal started in 1862 another canal, Ismailia canal, was constructed in the same time to sustain thousands of workers with water, food and other requirements. El-Mawany area and Nemra Ceta area showing the oldest Ficustrees are located near the construction of those canals. Importance of cultivating F. benghalensisat that time not only returns to their huge shade but also to their medicinal importance that could help in treatments of different diseases.

Based on age dating results, the oldest F. benghalensisis 394 years old cultivated in site number one (El Mawany), whereas the youngest tree is 96 years old cultivated in site number four (Nemra Ceta). The highest mean of age dating was recorded for the trees cultivated in site number three (304 years) located at Mohamed Ali, followed by Ficustrees cultivated in site number one (242 years) located at El-Mawany area. The lowest mean of age dating was recorded for Ficustrees cultivate in site number four and two (229, 216 years respectively). Correlation analysis indicates the direct correlation between age dating, cover, height, CAB, and CBH. CBH was the most important parameter could be used to predict the age dating of F. benghalensis. The results showed very important notes about growth mode of Ficus benghalensis: (a) average number of annual rings per centimeter ranges from 13 and 14 annual rings and (b) Ficustree with age of 96 years has height 3 m and diameter at breast height equals 14 cm and the oldest tree has height and diameter equal 11 m and 57 cm, respectively.

Age dating of Ficus benghalensisdata may be interpreted with one of the following two hypotheses. First, these trees may be introduced with age ranges from 150 to 200 years (about 20–30 cm diameter, and 5–7 m height) and connected with the Suez Canal construction for shade and medicinal importance. The second hypothesis returns the cultivation of these trees to the age before the construction of Suez Canal, and the populations of F. benghalensiswere selected to be near to the route of Suez Canal and Ismailia canal to get benefit from their shade and medicinal importance.

10.1 Chemical constituents

Ficus benghalensisplant is an ever green plant of family Moraceaehaving many chemicals compounds present in this plant. There are so many researchers work out on this plant species. According to Patil et al. [27] described that in leaves, stem, bark; root and aerial root have different chemicals so this plant is having medicinal importance.

In Ficus benghalensisleaves have quercetin-3-galactoside, rutin, friedelin, taraxoseterol, lupeol, B-amyrin along with psoralen, bergapten and B-sisterol.

The bark of Ficus benghalensishas 5,7 dimethyl ether of lucope-largonidin 3-0--L rhamnoside and 5,3, dimethyl ether of leucocynidin 3-0--D galactosyl cellobioside, glycoside, 20-tetra-triaconthene-2-one, 6-heptatriacontene-10-one, pentatriacontan-5-one, beta sitosterol-alpha-D-glucose and meso-inositol Earlieds, glucoside, 20 tetrattria-conthene-2-one, 6-heptaria contene-10-one, pentatriacontan-5-one, beta sitosterol-alpha-D-glucose, and me-so inositol, leucodelphinidin derivative, bengalenoside: aglucoside, leucopelargonin derivative, leucocynidin derivative, glycoside of leucopelargonidin have been isolated from the bark of Ficus benghalensis.

The fruit of Ficus benghalensistraditional use of folk medicine for respiratory disorders and certain skin disease. According to Ayurvedic system of medicine Ficus benghalensisLinn (banyan tree) is well known to be useful in diabetes. This attracted the attention of many earlier workers who studied the hypoglycemic effect from the bark of Ficus benghalensis. Ficus benghalensisLinn is a large evergreen tree found throughout forest tracts of India. It is popular Indigenous system of medicine like Ayurveda, Siddha, Unani and Homeopathy. In traditional system of medicine various plant parts such as stem, bark, and root bark aerial roots, vegetative buds, leaves, fruits and latex are used in dysentery, diarrhea, diabetes leucorrhoea, menorrhagia, nervous disorders, tonic and astringent.

11. Medicinal importance of Ficus benghalensis

11.1 Anthelmintic activity

The extracts from Ficus benghalensisnot only to paralyze, but also to kill the earthworms. The aqueous and methanolic extracts were found to be more effective to execute the earthworm when compared to antihelminthic drugs [28].

11.2 Anti-inflammatory activity

The ethanolic (300 mg) and petroleum ether extracts (600 mg/kg/day) of Ficus benghalensis, considerably abridged (P < 0.05) carrageenan-induced paw edema in rats. The ethanolic and petroleum ether extracts showed a greater anti-inflammatory effect compared with the standard drug Indomethacin. The results indicated the ethanolic extract of Ficus benghalensisexhibited more significant activity than petroleum ether in the treatment of inflammation [27].

11.3 Anti-stress and anti-allergic

Various extracts of Ficus benghalensisbark was screened for its anti-allergic and anti-stress potential in asthma by milk-induced leukocytosis and milk-induced eosinophilia. Aqueous, ethanol, and ethyl acetate extracts showed significant decrease in leucocytes and eosinophils in the order given while petroleum ether and chloroform extracts were inactive. This shows the application of polar constituents of F. benghalensisbark as anti-stress and Anti-allergic agents in asthma [29].

11.4 Antioxidant activity

The extract was examined for its antioxidant activity by DPPH radical scavenging activity, hydroxyl radical scavenging activity, reducing capacity, hydrogen peroxide activity, total phenolic content using Folin-Ciocalteu’s phenolic reagent. The extract showed extreme scavenging of DPPH radical (96.07%) at 250 μg mL−1 concentration and hydrogen peroxide (69.23%) at 1000 μg mL−1 concentration. The extract shows good results when compared with other compounds. This shows the scavenging activity of the extract [30].

11.5 Antitumor activity

The chloroform extract of the fruit of Ficus benghalensishas shown toxicity in the brine shrimp (Artemia salina) bioassay (LC50 < 1000 μg/ml). It also possessed antitumor activity in the potato disc bioassay (% tumor inhibition >20%).

The other tested extracts showed no marked inhibition on the uptake of calcium in to rat pituitary cells GH4C1. The results support the traditional use of these plants in Folk medicine for respiratory disorders and certain skin diseases [9, 10].

11.6 Antidiarrheal activity

The ethanol extract of the hanging roots of Ficus benghalensishas been evaluated for antidiarrheal activity against different investigational models of diarrhea in rats. The extract (400 mg/kg, orally) has shown significant inhibitory activity against castor oil induced diarrhea (extract fed rats had 2.21 ± 0.27 defecations per animal in 4 hours; control 4.0010.33, P < 0.001) and PGE2 induced enteropooling (for extract fed rats the value reported is 1.25 ± 0.15 in terms of intestinal fluid; control 0.78 ± 0.11, P < 0.02) in rats. The extract has also been significantly effective in reducing gastrointestinal mobility (extract fed rats: 50.2 ± 2.7%; control 79.412.76%, P < 0.001) in charcoal meal test in rats [31].

11.7 Antimicrobial activity

The chloroform concentrates of the product of Ficus benghalensishas likewise indicated inhibitory activity (0.5 mg/disc) against the bacterium Micrococcus luteus(18–26 mm diameter inhibition zone), which was not inhibited by kanamycin (100 μg/disc), streptomycin (100 μg/disc) or penicillin (5 μg/disc). Streptococcus faecalisand Streptococcus faeciumwere also inhibited by the fruit extract (17–20 mm inhibition zone). Other bacteria such as Bacillus cereus, B. megaterium, Staphylococcus aureus, Streptococcus epidermis, Streptococcus lactis, Escherichia coli, Klebsiella pneumonia, Proteus vulgarisand Pseudomonas aeruginosawere inhibited to a lesser extent (16–19 mm inhibition zone) [9, 10].

11.8 Antifungal activity

Mitosporic fungi and several sterile forms were isolated as endophytes from the leaf tissues and aerial roots of Ficus benghalensis. Although similar number of endophyte species was present in lamina and petiole, the endophytic fungi more densely colonized the petiole. The species composition and the colonization frequency of the endophytes were more for the aerial roots entering the soil when compared with those growing in the air since the roots recruited some endophytes from the soil.

The endophyte assemblages of the leaf and aerial root and of the aerial root growing in the air and soil showed little overlap suggesting that the nature of the host tissue as well as the environment determine the endophyte composition of a host [31].
