1 Aims: To evaluate the ability of grapevine ecosystem fungi to degrade histamine, tyramine 2 and putrescine in synthetic medium and in wines. 3 Methods and Results: Grapevine and vineyard soil fungi were isolated from four locations of 4 Spain and were subsequently identified by PCR. A total of 44 fungi were evaluated for in 5 vitro amine degradation in a microfermentation system. Amine degrad...
Mekuria, T. A., Gutha, L. R., Martin, R. R., and Naidu, R. A. 2009. Genome diversity and intraand interspecies recombination events in Grapevine fanleaf virus. Phytopathology 99:1394-1402. Grapevine fanleaf virus (GFLV) was documented in self-rooted vines of four grapevine (Vitis vinifera) cultivars in eastern Washington. GFLV was found as mixed infection in cvs. Pinot Noir, Chardonnay, and Cab...
the major objective of seedless grape breeding program is production of grapes with high quality. breeding of seedless grapes is difficult because the embryos are aborted after fertilization. embryo rescue technique is utilized to obtain plants from crosses between seedless cultivars. in the present study, the effect of paternal genotypes and different iaa concentrations in presence of ba appli...
Primary bud necrosis in grapevine is a physiological disorder observed in the compound buds. This study was conducted to investigate the anatomical changes in cv. Askari grapevine in winter dormant buds. Bud samples were taken from Askari grapevine at Sisakht vineyards, south-western of Iran. Compound buds were dissected and assessed under a binocular microscope at 10-40x magnification and a di...
Grapevine (Vitis vinifera L.) is a clonally propagated major fruit crop. In grapevine, identification of genotypes with amplographical features is often based on mature plant characteristics that may be affected by environmental conditions. This approach lacks objectivity and reliability. Recently, molecular markers have proved to be supplementary techniques to analyze genetic diversity and exa...
A pair of degenerate primers, GMPF1 and GMPR1, was designed on the basis of alignment of previously reported Grapevine fanleaf virus (GFLV) movement protein (MP) nucleotide sequences from Iran and other parts of the world. cDNA was synthesized by the use of Oligo d(T)18 from total RNA extraction from each diseased grapevine leaf sample and subjected to polymerase chain reaction (PCR) with the d...
Some cultivars of grapevine have very compact cluster which adversely affect its quality and marketability. ‘Yaghouti’ is a commercial early table grape cultivar that has very compact clusters. The present study was conducted to assess the effects of mechanical and chemical thinning as well as GA3 application on cluster morphology and berry size of grapevine cv. ‘Yaghouti’. Treatments were chem...
Abstract Grapevine ( Vitis vinifera ) is widely applicated in food industry, which shows high economical and nutritional values. However, growth of grapevine was usually affected by various environmental stresses, such as salt, drought disease. Ubiquitin fusion degradation protein 1 (UFD1) an essential ubiquitin-recognition facilitates regulation stress response through ERAD pathway. Even thoug...
Grapevine (Vitis vinifera L [...]
objective: yield components and genetic contribution have the most important in final yield and breeding programs of crop plants. for this purpose, 20 varieties of grapevines with russia origin were evaluated in urmia and takestan research station (under full irrigation and drought stress). methods: twenty grapevine genotypes were evaluated in urmia and takestan research station (under full irr...
