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...

background and objectives: grape has high nutritional value and it is an economically important horticultural plant in the world. iran has seventh producer grape rank in the world. today tissue culture is one of technique which can be used in grape propagation and breeding. material and method: in order to optimization of callus induction and micropropagation of grape in vitro condition, this i...

consumers prefer seedless grapes for table and raisin grape industry. release of new superior seedless grape cultivars is one of the main objectives in grape breeding programs. embryo rescue is one of the techniques to develop a new seedless cultivar. therefore, in this study, the effects of bud flower spraying with ba (50 ppm) and ccc (200 ppm) before blooming were studied in ‘flame seedless’ ...

in order to study the different concentrations of gibbererlic acid and girdling on quantity and quality improvement of grape cv, askari an experiment was carried out in kashmar region on 2012 as factorial in a complete randomized block design.in this experiment the effect of gibberellin at four concentration in two time of flowering and girdling at four time in four replication were performed. ...

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...

Thioredoxins (Trxs) are small ubiquitous disulfide reductases that participate in dithiol-disulfide exchange reactions. In contrast to animals and prokaryotes that typically possess one or a few genes encoding Trxs, higher plants contain eight different Trx types: f, m, x, y, z, o, s, and h. Trx h with multiple forms is involved in different processes such as seed germination, cellular protecti...

this research was carried out to investigate the cold-hardiness of grapevine buds in a factorial experiment base on completely randomized design (crd) with 80 treatments and three replications. treatments included four cultivars (rish-baba, siyah-e-shiraz, askari and bavanati), four sampling dates (6th dec, 5th jan, 4th feb and 6th mar 2009 and 2010) and low temperature levels (+5, -7, -15, -22...
