Influence of Endomycorrhizal Fungi on the Growth of Tropical Plant Species
In Southeast Mexico, deforestation in tropical forests is considered an environmental concern. Deforestation favours the growth of plants that compete with species of interest, which generally present slow growth. In order to promote greater growth in less time of the forest species used in reforestation and two crops of regional interest, the effect of including Rhizophagus intraradices in the seed or the root system of seedlings were investigated to evaluate its influence on growth and allocation of dry matter in the aerial and radical part, in addition to the concentration of N, P and Ca. Also, two additional collections with morphological characteristics of Glomus sps were included in T. donnell-smithii. The results indicate that biofertilisation with R. intraradices induces increased growth and is differential in stem and root dry matter allocation over time, in addition to increasing nutrient content in plant tissue.

Responses of Agronomically Important Tropical Crops to the Application of Brassinosteroid
Brassinosteroids (Br) have been shown to favor the growth and reproduction of crops under adverse environmental conditions, which negatively affect their growth and production. In order to solve some of the problems in the field with various perennial crops, the application of a homobrassinolide (HBr) (CIDEF-4) has been investigated under in vitro and ex vitro conditions to evaluate growth at different concentrations in Musa spp. L. and Saccharum officinarum L and in the field with foliar applications in Theobroma cacao L, Mangifera indica L and Coffea arabica L. to evaluate yield and quality of fruits. Morphological and physiological yield components were recorded. The results indicate in the in vitro evaluations, increased regrowth height and ex vitro differences in growth are improved by increasing the number of applications. In cocoa and coffee plants, flowering and yield are influenced. The high concentrations applied did not necessarily increase the crop yield or the combination with potassium nitrate. In mango, the quality of the fruits was better when applying the HBr alone or in combination with nitrate in fruit firmness, and total soluble solids improved.
