(Submitter supplied) Grapevine is a perennial crop often cultivated by grafting a scion cultivar on a suitable rootstock. Rootstocks influence scions, particularly with regard to water uptake and vigor. Therefore, one of the possibilities to adapt viticulture to the extended drought stress periods is to select rootstocks conferring increased tolerance to drought. However, the molecular mechanisms associated with the ability of rootstock/scion combination to influence grape berry metabolism under drought stress are still poorly understood. more...

(Submitter supplied) Studying the effect of varying durations (1, 7 and 14 days) of locally applied heat stress on grape berries at three developmental stages (middle green, veraison and middle ripening). Among various environmental factors, temperature is a major regulator affecting plant growth, development and fruit composition. Reproductive development of grapevine and berry composition, are both highly influenced by temperature. more...

(Submitter supplied) Genotype, climate, soil qualities, and rootstocks are among the main factors that influence grape development as well as fruit and wine composition. In this work, the rootstock/scion interactions were studied using transcriptomic and metabolic approaches on leaves of Gaglioppo variety, grafted onto thirteen different rootstocks growing in the same locations. The experiments were performed in a vineyard in the south of Italy, characterized by the Mediterranean climate with warm and dry summers. more...

(Submitter supplied) Global gene expression analysis of grapevine cv. Pinot Noir berries during development and ripening. Time-course comparison of samples collected at three developmental stages (stages 33, 34 and 36 according to the modified E-L system, ref: Coombe BG, Aust J Grape Wine Res 1995, 1: 104-110) during three seasons (2003, 2005 and 2006). Data for each of the three seasons were normalized independently within each season, using gcRMA. more...

(Submitter supplied) Leaf removal is a grapevine canopy management technique widely used to modify the source-sink balance and/or microclimate around berry clusters to optimize fruit composition. In general, the removal of basal leaves before flowering reduces fruit set, hence achieving looser clusters, and improves grape composition since yield is generally curtailed more than proportionally to leaf area itself. Albeit responses to this practice seem quite consistent, overall vine performance is affected by genotype, environmental conditions, and severity of treatment. more...
