Citrus represents one of the most widely grown crops on planet, extensively cultivated for both fresh fruit and juice markets. The productivity citrus orchards can be seriously affected by highly aggressive pathogenic bacteria, such as Xanthomonas citri subsp. citri, Xylella fastidiosa pauca currently Candidatus Liberibacter asiaticus. Different microbiological biocontrol agents have been descr...

‘Aliza’ is a new pomelo × mandarin hybrid (Citrus maxima, cv. Red Chandler Citrus reticulata, Ora) developed by the Israeli citrus breeding program at Volcani Institute. Here, we aimed to characterize quality and flavor of fruit as compared other commercial fruit, specifically (C. maxima), grapefruit paradisi), orange sinensis) reticulata). fruits have similar size grapefruits, but thinner peel...

The generation of co-products continues at an accelerating pace, driven by population growth. Many of these co-products can be included in ruminant feed, which has the ability to transform them into good quality animal protein, and also help to reduce the disposal of undesirable residues to the environment. One of the co-products with potential use in animal feed, the citrus pulp, represents re...

Conversion of wastewater to reclaimed water for crop irrigation conserves water and is an effective way to handle a growing urban problem: the disposal of wastewater. Water Conserv II is a large reclaimed water project developed by Orlando and Orange County, Fla., that presently irrigates ≈1900 ha of citrus. The project includes a research component to evaluate the response of citrus to irrigat...

Mandarin hybrids were treated with wax and resin coatings having differing oxygen permeabilities. After storage for 7 days at 21 °C, fruit with coatings having O2 permeability 1.1×10 mol m s m Pa were rated by a sensory panel as markedly less fresh than fruit with higher permeability coatings. These low-permeability coatings were those composed mainly of shellac and wood resin. The flavor chang...

In natural-light labeling of fruits and vegetables, the desired information is etched onto the produce surface using a low-energy carbon dioxide laser beam (10,600 nm). Etched characters are formed by surface depressions in the epidermis that may facilitate entrance of decay and pathogenic organisms. The objective of this study was to determine the effects of natural-light labeling and differen...

Putrescine (Put) increased 68% in lemon (Citrus limon (L.) Burm. f. cv Bearss) flavedo, 39% in grapefruit (C. paradisi Macf. cv Marsh) flavedo, 49% in grapefruit juice, and 149% in pepper (Capsicum annuum L. cv Early Calwonder) pericarp when fruits were stored at chilling temperatures. In lemon flavedo, the coefficient of correlation (r(2)) between Put concentration with severity of chilling wa...

Chlorophyll and carotenoid are the main pigments that responsible for coloration of citrus fruit. The changes in their contents related to development stage During fruit maturation, carotenoids massively accumulated flavedo juice sacs, while chlorophyll decreased rapidly. In contrast, increase content decrease observed during regreening process. addition, plant hormones environmental conditions...

Combined spraying of gibberellin (GA) and prohydrojasmon (PDJ) was an effective method to prevent the physiological disorder peel puffing in citrus fruit. However, GA PDJ combined treatment inhibited carotenoid biosynthesis during fruit ripening process, which led mature with poor color. In present study, improve coloration PDJ-treated fruit, effects postharvest treatments two auxins, indole-3-...
