Distribution of the citrus nematode (Tylenchulus semipenetrans) was studied over 18 months in a 6-year-old orchard of grapefruit (Citrus paradisi cv. Ruby Red) on sour orange (C. aurantium) rootstock. The 1.8-ha orchard was under chemical weed control, no tillage, and flood irrigation. Highest numbers of nematodes were found in the top 15 cm of the soil profile. The nematode population peaked i...

Chemical control of the citrus nematode, Tylenchulus semipenetrans Cobb, has consistently increased yield of grapefruit on sour orange rootstock in Texas. In this study, data from chemical control tests conducted from 1973 to 1980 were analyzed to determine the relationship between nematode counts and grapefruit yield and fruit size. The correlation between yield and nematode counts was negativ...

In Citrus, flower induction represents the transition from vegetative to reproductive growth. The regulation of is mainly triggered by exposure low temperatures and water-deficit stress, which activates signaling cascade leading an increased expression citrus orthologs FLOWERING LOCUS T (CiFT). this study, relationship between rootstock under Mediterranean field conditions was investigated moni...

‘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...

Plants activate antioxidant defense mechanisms under stress, which help maintaining the structural integrity of cell components and possibly reduces oxidative damage.  Low temperature stress leads to the production of reactive oxygen species and oxidative damage to plants. In this study, the effect of putrescine and proline on reducing the production of reactive oxygen species and increasing th...

Background: During the last decades, a huge body of evidence has been accumulated suggesting that Citrus fruits and their juices might have a role in preventing many diseases including cancer. Objective: To summarize the numerous evidences on the potential of Citrus juices and their extracts as anticancer agents. Data sources: A systematic review of articles written in English using MEDLINE (19...

Methyl bromide fumigation is widely used as a phytosanitary treatment. Mexican fruit fly, Anastrepha ludens (Loew) (Diptera: Tephritidae), is a quarantine pest of several fruit, including citrus (Citrus spp.), exported from Texas, Mexico, and Central America. Recently, live larvae have been found with supposedly correctly fumigated citrus fruit. This research investigates the efficacy of the pr...
