Intra-varietal variability of Romanesco variety (Vitis vinifera L.)

Inter- and Intra-Varietal Genetic Variability in Vitis vinifera L

Biological activities of Vitis vinifera L. leaves

The fractions of different polarity, namely chloroform, ethylacetate, n-butanol, and remaining water fractions, were fractionated from an aqueous extract of V. vinifera leaves. The antibacterial, antifungal, antiviral, antioxidant activities, and total phenolic content of these fractions were investigated. The chloroform fraction showed a promising effect against Herpes simplex virus type-1 (HS...

Determination of piceid and resveratrol in Spanish wines deriving from Monastrell (Vitis vinifera L.) grape variety.

The presence of stilbenes in wine is becoming an important issue due to their claimed relation to a low incidence in coronary diseases and their increasing implication as cancer chemopreventive and neuroprotective agents. Total resveratrol content, quantified as glucoside and aglycone forms of resveratrol, has been determined in a survey of 45 Monastrell monovarietal Spanish red wine types (aro...

In vitro Regeneration of Grape (Vitis vinifera L.) cv. Perlette

Factors like slow and seasonal multiplication and infection with pathogens have constrained the use of conventional plant propagation methods, thus lead to development of new and novel methods of propagation like in vitro multiplication which ensures the production of virus and disease free elite planting material in large numbers. In the present work, in vitro regeneration protocol has been st...

Maintenance of Pollen Germination Capacity of Vitis Vinifera L. (vitaceae)

Pollen germination of Vitis vinifera L., of the family Vitaceae was examined in fresh and stored pollen upto 48 weeks at different temperature i.e., refrigerator (+4C), freezer (-20C, -30C) and freeze drier (-60C). Pollen stored at low temperature showed better germination percentage as compared to pollen stored at +4C and fresh. Freeze dried pollen (-60C) showed the highest germination percent...
