Citrus aroma and flavor, chief traits of fruit quality, are derived from their high content in essential oils of most plant tissues, including leaves, stems, flowers, and fruits. Accumulated in secretory cavities, most components of these oils are volatile terpenes. They contribute to defense against herbivores and pathogens, and perhaps also protect tissues against abiotic stress. In spite of ...

Plant growth and K influx responses to K supply were studied in two citrus rootstocks (Carrizo citrange, Citrus sinensis [L.] Osb. × Poncirus trifoliata [L.] Raf.; Cleopatra mandarin, Citrus reshni Hort. ex Tanaka) to determine mechanisms of K acquisition. Seedlings of Carrizo citrange (CC) and Cleopatra mandarin (Cleo) were grown in aerated nutrient solutions for 40 days with either no K added...

A morphometric and molecular characterization of Brevipalpus sp. close to the group cryptic species within californicus s.l. bearing only one solenidion on tarsus II was conducted, its capacity acquire inoculate citrus leprosis virus C (CiLV-C) orchid fleck virus, strain-citrus (OFV-citrus), determined. For study, photomicrographs mites from two colonies kept in laboratory were taken: derived a...

Abstract Residues are generated after the processing of citrus fruits and can be used for essential oil extraction. Thus, objective this work was to evaluate composition, yield, quality proven 30 orange varieties, as an alternative better use its residues. The peels were crushed subjected hydrodistillation in a Clevenger-type. samples submitted Entirely Randomized Design (DIC) results analyzed ...

Citrus is grouped under the salt sensitive crops. Mycorrhizal fungi, a symbiotic relationship between plant roots and beneficial fungi, are supposed to impart the stress tolerance in the host plants. The stress tolerance improved due to Arbuscular Mycorrhizal fungi (AM fungi) colonization can be attributed to enhanced mineral nutrition. In the present study the efforts are made to evaluate the ...

Carrot purple leaf disease was first reported in 2006 in the state of Washington and was associated with Spiroplasma citri. The disease also was reported in California in 2008. The objectives of this work were to fulfill Koch's postulates and to determine 1) whether the beet leafhopper, Circulifer tenellus (Baker) (Hemiptera: Cicadellidae), transmits carrot [Daucus carota L. subsp. Sativus (Hof...

Citrus, as one of the globally important fruit trees, has been an object of interest for understanding genetics and evolutionary process in fruit crops. Meta-analyses of 19 Citrus species, including 4 globally and economically important Citrus sinensis, Citrus clementina, Citrus reticulata, and 1 Citrus relative Poncirus trifoliata, were performed. We observed that codons ending with A- or T- a...

Interstocks can reduce toxic ion accumulations in leaves of budded citrus trees, but the mechanism is not understood. We grew sour orange (Citrus aurantium L.; SO) seedlings, budded trees of 'Salustiano' orange (Citrus sinensis L. Osbeck; SAO) on SO, 'Verna' lemon (Citrus limon L. Burm. f; VL/SO) and interstock trees (VL/SAO/SO) in pots of sand watered with nutrient solution containing 5 (contr...
