Dr. Mateus Pereira Gonzatto is a Professor of Citrus and Mango Ecophysiology, in the Department of Agronomy at the Federal University of Viçosa, Brazil. He is a director of representations and publications of the Brazilian Fruit Growing Society (SBF). He researches topics such as citriculture, scion/interstock/rootstock interactions, plant growth regulators, biostimulants, fruit thinning, fruit maturation, and orchard management.
This book highlights advances in citrus production, focusing on horticultural and human health aspects. In contrast to most publications on citrus, this book discusses both citrus production and the effects of citrus on human health. It is organized into three sections on “Citrus Physiology and Production Technology”, “Citrus Pests and Disease”, and “Citrus in Human Health”. Chapters address citrus production, physiology, diseases, and pests, and much more.
Go to the bookThere is a worldwide trend regarding high density of fruit planting. In the last four decades, the Brazilian citriculture had increased the average planting density by more than 80%. The main reasons for this increase are the fast return on invested capital, the easiest management of cultural practices, and the control of strategies epidemics-associated (e.g., Huanglongbing). In that regard, the use and development of dwarf and semi-dwarf rootstocks are essential. The main dwarf rootstock known in citriculture is the Flying Dragon trifoliate orange [Poncirus trifoliata (L.) Raf. var. monstrosa (T. Itô) Swing.] which greatly reduces the canopies volume allowing the design of dense and ultra-dense orchards. Currently, several citrus breeding programs are producing new cultivars of dwarf and semi-dwarf rootstocks. In this chapter, citrus rootstocks with dwarfing potential were approached including physiological aspects, horticultural performance, and behavior to phytosanitary problems. In addition to Flying Dragon, there are other dwarfing rootstocks which are hybrids of trifoliate oranges, like citrandarins, citrangedarins, citrumelandarins, and citrimonianandarins. Dwarfing rootstocks are one of the leading alternatives for citrus orchards in high-density planting systems.

Essentials oils from citrus have anti-inflammatory and antioxidant activity. Furthermore, terpenes are their main phytochemicals, namely limonene is the most important one. As terpenes are permeation promoters, they have been used to improve transdermal delivery of drugs. In addition, a proper oil source is a key factor to obtain desired phytochemicals. Recently, polymeric nanoparticles, solid lipid nanoparticles, nanostructured lipid carriers, nanoemulsions, liposomes and elastic liposomes as carriers of citrus essential oils or citrus terpenes have been developed to achieve more effective formulations. In this chapter, the most recent publications on nanocarriers containing citrus oils or citrus terpenes were addressed. In that regard, citrus oil or terpenes loaded in nanotechnological systems improve drugs skin permeation. Besides, terpenes loaded in nanoparticles also increase transdermal delivery of drugs. As essential oils and their respective terpenes are volatile compound and prone to oxidation, its encapsulations reduce oxidation and volatility. Hence, an improved antioxidant activity can be obtained. Therefore, nanoformulations of citrus oils or citrus terpenes are potential approaches to skin topical and transdermal delivery.
