Stability of Ampelometric Characteristics of Vitis vinifera L. cv. 'Syrah' and 'Sauvignon blanc' Leaves: Impact of Within-vineyard Variability and Pruning Method/Bud Load [PDF]
Historically, grapevine (Vitis vinifera L.) leaf characterisation has been a driving force in the identification of cultivars. In this study, ampelometric (foliometric) analysis was done on leaf samples collected from hand-pruned, mechanically pruned and

COMPARISON OF GRAPE SEEDLINGS POPULATION AGAINST DOWNY MILDEW BY USING DIFFERENT PROVOCATION METHODS
This research was conducted to compare a laboratory technique leaf disk with hotbed and field evaluations in the screening of large populations of grape seedlings (Vitis spp.), towards downy mildew (Plasmopara viticola Berk.

Fungal Endophytes of Vitis vinifera—Plant Growth Promotion Factors
Endophytes are microorganisms that live asymptomatically inside plant tissues. They are beneficial to their host in many aspects, especially as a defense against foreign phytopathogens through the production of a variety of metabolites.

Photosynthesis of the grapevine (Vitis vinifera) inflorescence [PDF]
To further characterize carbohydrate physiology in grapevine flowers, we examined inflorescence autotrophy in the 'Gewurztraminer' and 'Pinot noir' cultivars, which differ in sensitivity to flower abscission. In both cultivars, positive net photosynthesis occurred in inflorescences.

Evaluation of crown gall resistance in Vitis vinifera and hybrids of Vitis spp. [PDF]
Relative levels of crown gall susceptibility were determined in 17 genotypes of Vitis spp. by inoculating a diverse set of Agrobacterium vitis strains, measuring gall size and weight, and percentage of inoculated sites with galls.

Introgression Among Cultivated and Wild Grapevine in Tuscany
Wild grapevine, Vitis vinifera L. subsp. sylvestris (Gmelin, Hegi) is spontaneous to Europe and common in Tuscany. In this study, wild grapevines were identified in 22 populations from eight locations in Tuscan Maremma (Grosseto and Siena province).

STARCH AND SUGARS OF VITIS VINIFERA [PDF]
This investigation on the carbohydrate values within Vitis vinifera is included in a general study of nutrition. Presumably, a better understanding of the physiology of the grapevine would result in improved viticultura! practices. It would serve as a suitable basis for evaluating the analytical results obtained by studying the carbohydrate nutrition ...

Chloride accumulation in some hybrids and backcrosses of Vitis berlandieri and Vitis vinifera [PDF]
F1 hybrid populations from crosses of 2 selections of V. berlandieri and 4 cultivars of V. vinifera showed generally low chloride accumulation, as in V. berlandieri, with some small variations related to particular parents.

Gombarezisztencia gének térképezése szőlőben = Mapping resistance genes against fungi in grapevine [PDF]
Lisztharmat (PM) és peronoszpóra (DM) rezisztencia génekkel kapcsolt markerek szelekcióra való alkalmasságát vizsgáltuk szőlő inter-és intraspecifikus térképezési populációiban.
