Effect of pre-bloom leaf removal on grape aroma composition and wine sensory profile of Semillon cultivar.

Background: Early leaf removal at pre-bloom is an innovative viticultural practice for regulating yield components and improving grape quality. The effects of this technique on vine performance, grape composition and wine sensory profile of Semillon variety were assessed.

Results: Pre-bloom leaf removal enhanced canopy porosity, total soluble solids in musts and reduced cluster compactness.

Time-Resolved Investigation of Molecular Components Involved in the Induction of [Formula: see text] High Affinity Transport System in Maize Roots.

The induction, i.e., the rapid increase of nitrate ([Formula: see text]) uptake following the exposure of roots to the anion, was studied integrating physiological and molecular levels in maize roots.

Influence of vineyard altitude on Glera grape ripening (Vitis vinifera L.): effects on aroma evolution and wine sensory profile.

Background: Environmental factors have been acknowledged to greatly influence grape and wine aromas. Among them, the effect of altitude on grape aroma compounds has scarcely been debated in literature available to date. In the present study, we investigated the influence of altitude on grape composition and aroma evolution during ripening of Vitis vinifera L.

Induction of high-affinity NO uptake in grapevine roots is an active process correlated to the expression of specific members of the NRT2 and plasma membrane H-ATPase gene families.

The phenomenon of NO3- induction in plant roots has been characterised both in herbaceous and woody plants. Grapevine (Vitis vinifera L.) plants, hydroponically grown, showed an increase in NO3- uptake rate in response to anion treatment for different periods in the nutrient solution after 1 week of NO3- deprivation.
