Research study on the dynamics of the content of photosynthetic pigments at some grapevine varieties in the vegetation year 2013

Abstract

Grapevine plantations and environmental conditions create an entity in which interdependence and mutual conditioning represent a normal state of things, the higher influence being exerted by the environmental element toward the vegetal organisms. The modifications of environmental conditions lead to modifications in the metabolism, the development of growth and development processes, with positive or negative effects on both plant quality and vitality. Atmospheric and pedological draught perturb the physiological and biochemical processes having significant repercussions on cellular ultrastructure and physiological processes. Climatic changes and their impact on vineyards represent a highly important issue for the researchers of various fields of activity.
