BACKGROUND AND AIMS Despite the widespread use of dwarfing rootstocks in the fruit-tree industry, their impact on tree architectural development and possible role in the within-tree balance between growth and flowering are still poorly understood, in particular during the early years of growth. The present study addressed this question in apple trees, through a detailed analysis of shoot popula...

(ibl)berellinl-like stulstances occtlr in mianv higher pllants (1 2, 17, 20). and sexeral have beenl idenitified (12). Tlhe presence of gibberelliln-like activity in seedless fruit, of V'itis v'iiifcra L. was (lenlonstrated in 1960 by Coombe (1). Although it seemiis probable that sulch a widely spread hormonie also would be invxolved in the groxwth of seede(d fruit, Coombe was unable to demnons...

Phenolic compounds were extracted from European and Japanese grapevine species (Vitis vinifera and V. coignetiae) seeds using 80% methanol or 80% acetone. The total content of phenolic compounds was determined utilizing Folin-Ciocalteu's phenol reagent, while the content of tannins was assayed by the vanillin and BSA precipitation methods. Additionally, the DPPH free radical and ABTS cation rad...

Grape is one of the most important fruit crops worldwide. The suitable geographical locations and productivity of grapes are largely limited by temperature. Vitis amurensis is a wild grapevine species with remarkable cold-tolerance, exceeding that of Vitis vinifera, the dominant cultivated species of grapevine. However, the molecular mechanisms that contribute to the enhanced freezing tolerance...

Grapevine (Vitis spp.) is one of the most important socio-economically plants in global scale, and need for its breeding increasing. In viticulture, mutation more promising than crossbreeding new genotypes from natural genetic diversity. Polyploid outperform their diploid relatives several respects. this study, efficacy oryzalin N2O mutagens induction polyploidy was investigated by applying dif...

Vitis vinifera L.is a traditional Asian herb widely used for different health problems. In thepresent research, the ethanolic and the aqueous extracts of Vitis vinifera L. leaves collected fromshrub, grown in Tunisia, were prepared and evaluated for the antileishmanial activity againstLeishmani ainfantum promastigotes. The inhibitory concentration 50 (IC50) was determined andthe results showed ...

The present study was designed to evaluate the phytochemical profile and the anti-inflammatory, analgesic and anti-convulsant activity of methanolic extracts of Allium sativum, L.(peel of the bulb), Arachis hypogaea, L. (fruit shell), Citrus limon, L. (rind of the fruit), Punica granatum, L.(rind of the fruit) and Vitis vinifera, L.( seed).
