Due to the problems encountered in routine morphological and physiological procedures that are used in yeast identification, DNA-based methods have recently been developed. In the present study, l66 yeast strains were isolated from several apple and citrus cultivars. After analysis by basic morphological methods, the ITS1 and ITS2 regions of the isolates were amplified separately, and the isola...

Orange is one of the most horticulturally important and widely cultivated Citrus species. cultivar improvement via conventional breeding strategies normally impeded by factors related to its reproductive biology. The present study was undertaken investigate optimization growth regulators’ composition media in vitro propagation orange from nodal segment explants. explants were collected sweet cu...

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...

Iron chlorosis is one of the major abiotic stresses affecting fruit trees and other crops in calcareous soils and leads to a reduction in growth and yield. Usual remediation strategies consist of amending iron to soil, which is an expensive practice, or using tolerant cultivars, which are difficult to develop when not available. To understand the mechanisms underlying the associated physiopathy...

PRO-GEN® (arsanilic acid or P-G) has been shown to reduce acidity of Florida grapefruit as effectively as lead arsenate. A series of experiments in the 1987-88 citrus fruit sea son reconfirmed that P-G was effective for this use with con centrations of 600-1500 ppm. P-G is water soluble. However, deliberate attempts to wash it off immediately following spray application reduced its effectivenes...
