acidity; clementines; environmental factors; evolution; fruit drop; fruit maturity; fruit pulp; fruiting; hybrids; juices; mandarins; oranges; peduncle; ripening; sugars; total soluble solids; Corsica; Spain
Abstract:
... Citrus fruit development and ripening are complex processes involving physiological and biochemical changes that are under hormonal, nutritional and environmental control. One of the most evident phenomena in late maturation is shedding of ripe fruit. A study made in Spain on sweet oranges showed that fruit shedding was related to the increase of sugars content of fruit pulp juice. To investigate ...

Citrus tristeza virus; agronomic traits; clones; fruit quality; fruit yield; mutation; oranges; soil; temperature; vigor; Brazil
Abstract:
... ‘Pera’ sweet orange, one of the most important Brazilian sweet orange varieties, is high susceptible to Citrus tristeza virus (CTV), causing reduced yield and fruit quality. The ‘IAC’ clone, pre-immunized with a mild protective CTV isolate (‘PIAC’), is the most cultivated clone, but several other clones derived from spontaneous mutations have been selected. The agronomic performance of ...

Abstract:
... Penicillium spp. fungi are the most frequent pathogens associated to postharvest decay in citrus fruit. Pre- and postharvest chemical sprays are the most widespread methods to reduce decay incidence, but alternative substances have been reported as promising substitutes for postharvest treatments. Here we evaluated the effects of different combinations of sodium bicarbonate and potassium sorbate a ...

Abstract:
... Citrus fruits are widely recognized by their concentration of vitamin C and therefore as one of the major sources of ascorbic acid (AsA) for human nutrition and health. Moreover, AsA is the most abundant antioxidant in plant cells and plays important roles in many developmental and stress processes. The biosynthesis of AsA in higher plants has been elucidated recently and to date four, somehow int ...

Subject:
cortex; root systems; greening disease; callose; cell walls; sieve elements; trees; carbon; scanning electron microscopy; petioles; Citrus
Abstract:
... Phloem cells from HLB-affected trees become obstructed with callose and P-protein plugs. The presence of these plugs is believed to hinder the translocation of photoassimilates (nitrogenous and reduced carbon compounds) to the root system. However, even with seemingly collapsed phloem tissue, citrus trees remain viable and produce fruit for some time, suggesting the incomplete plugging of phloem e ...

The desire for more effective and efficient delivery of these services transformed them from “local” to “area-wide” (AW) supply of clean water and the collection of the garbage and disposal of sewage. Today, AW services (e.g. e ...

Autocidal control of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), has become the cornerstone of area-wide integrated pest management programs in many countries. In this technique a critical point is the mating success of released sterile males which should contribute to reduce wild populations. Till this moment the evaluation of mating success is not performe ...

Abstract:
... Xanthomonas citri subsp. citri, the causal agent of citrus canker, is a pathogen difficult to control. Excessive use of pesticides has caused environmental contamination and has resulted in the selection of resistant strains of many pathogens, so the search for alternative control methods is of great importance. Several essential oils have shown bactericidal activity. The objective of this researc ...
