grapevine is among some of the most important horticultural crops in the world and as well in iran. since last century attempts have been made throughout the world to improve grapes. research in grape breeding for the purpose of improving table grape as well as raisin traits has started since 1996 in iran with crossing some selected seedless (askary, yaghoti, bidane sefid (sultana) and bidane g...
Expression patterns of four candidate AREB/ABF genes and four DREB/CBF genes were evaluated in leaf and root tissues of five grape varieties ('Qalati', 'Kaj Angoor', 'Sabz Angoor', 'Siahe Zarghan', 'Bidane Safid') with differential response to drought stress. Among the AREB/ABF genes, AREB1 and ABF2 showed up-regulation in response to drought stress in leaf and root tissues of all varieties whi...
Drought stress, as the most important environmental stress, severely disrupts plant growth and limits production and yield more than any other environmental factor. Investigation of the role of drought stress conditions on plant morphological, physiological and photosynthesis characteristics may provide a tool to understand the basic drought resistance. To investigate the drought tolerance of I...
Seedlessness is the most important characteristic of fruit quality for raisin and table grapes. Grape breeding at University of Tehran, Karaj branch, Iran started in 1999 with crossing some selected seedless and seeded cultivars at the end of evaluation of 90 cultivars in grapevine collection of College of Agriculture in Karaj. Out of 1400 progeny obtained from 26 different crosses, 381 of them...

the influence of water deprivation on potted grape (vitis vinifera l.) was investigated. leaf mass area (lma) and biochemical responses, including chlorophyll, total protein, peroxidase activity, soluble carbohydrates, photosynthesis and stomatal conductance were assessed in leaves of ‘sahani’ and ‘bidane sefid’ grape cultivars subjected to progressive drought (soil water potentials of: -0.2, -...
Adaptation and defense responses are the consequences of exposure to drought stress in plants. Salicylic acid (SA) as a natural signaling molecule poses a significant impacts on various aspects of plant growth and development. This study investigates the effects of SA on carotenoids content, lipid peroxidation rate and antioxidant enzymes activities. A pot experiment was conducted using a facto...
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...
Abstract Background: Vitis vinifera has a number of flavonoids which applied as antioxidant and anti-cancer activity. The present study was carried out to investigate effects of seed, skin, juice and leaf extracts of five grape species gathered from Qazvin and Kashan provinces on lymphocyte proliferation. Materials and methods: This experimental study was done on grape species of Shahroodi, Bid...
investigating the role of drought stress conditions on physiological characteristics of plant may provide means to understand basic drought resistance. differences in leaf emergence rate, leaf relative water content (rwc), membrane stability index (msi), leaf mass area (lma), net photosynthesis (anet), stomatal conductance (gs), transpiration rate (e), intercellular co2 concentration (ci), ...
