Citrus Bent Leaf Viroid (CBLVd) and Dwarfing (CDVd), from genus Apscaviroid, are two of the widely distributed citrus viroids among eight reported to date. They have been found induce reduction in canopy volume fruit production trees on trifoliate orange hybrids rootstocks. Moreover, infected only with CBLVd or combinations Exocortis (CEVd), Hop Stunt (HSVd) CDVd associated a poor development r...

The citrus industry in Florida faces a destructive endemic disease, known as huanglongbing (HLB), associated with Candidatus Liberibacter asiaticus ( C Las), phloem-limited bacterium, and transmitted by the Asian psyllid (ACP). Rootstocks are regarded critical to keep production commercially viable help trees cope disease. Although most scions susceptible, some rootstocks HLB-tolerant may influ...

As in several fruit crops, citrus trees with decreased size allow for a higher planting density, which may lead to productivity and facilitate operations such as harvesting spraying. The use of dwarfing rootstocks is one the most feasible methods tree control, but few commercial varieties are available date. In this work, long-term performance Valencia sweet orange grafted onto 51 hybrid was ev...

The citrus industry is challenged by numerous arthropods, yet extensive research has not been conducted to determine the potential use of entomopathogenic fungi as endophytes in pest management strategies. Two inoculation methods (i.e., soil drench and foliar spray) using a suspension Beauveria bassiana (strain PPRI 5339 contained Velifer®) containing 4 × 107 conidia mL−1 0.01% Tween 80 were on...

Citrus cultivation involves the widespread practice of grafting, which has a significant impact on citrus development and fruit quality yield. However, understanding effect flavonoid compounds after different rootstock grafting have been limited. Flavonoid compounds, found at highest levels in peels, contribute to improving nutritional value. In this study, scion-rootstock interaction was inves...

Growth, gas exchange, root hydraulic conductivity, and drought response of seedling and rooted cuttings of Lovell and Nemaguard peach [Prunus persica (L.) Batsch], and Carrizo (Poncirus trifoliata x Citrus sinensis) and sour orange (C. aurantium L.) citrus rootstocks were compared to determine the influence of propagation method on these characteristics. Rooted peach cuttings had a higher propo...

New foreign rootstocks for peaches [Prunus persica (L.) Batsch] are now being introduced into the United States through commercial nurseries for future sales to stone fruit growers. Almost all of these rootstocks are complex Prunus L. hybrids that are propagated vegetatively. Past experience with foreign Prunus rootstocks has shown that extensive testing is critical to avoid potential problems ...

Lemon is a prominent citrus fruit that supports regional economies worldwide. Several agronomic and quality attributes are affected by the rootstock selection, thus its selection essential for successful grove. This study aims to compare of four lemon cultivars (‘Mikrokarpo Messaras’, ‘Nouvel Athos’, ‘Femminello Commune,’ ‘Zia gara Bianca’) grafted onto three rootstocks (‘Sour Orange’, ‘Yuma Po...

Previous work on citrus trees has shown that an interstock, grafted between the rootstock and scion combination, not only can improve tree growth, longevity, fruit production, and quality, but also can increase salinity tolerance. This research was designed to evaluate flooding responses of2-year-old 'Verna' lemon trees [Citrus limon (L.) Burm.; VL] either grafted on 'Sour' orange (C. aurantium...
