Specifics of water regime in Weigela x wagneri L.H. Baileyon th e black sea coast of Krasnodar region

Abstract

Water regime of different Weigelaxwagneri cultivars was studied by such physiological parameters as water stress, dry matter content and concentration of cell sap in the leaves. There were established some differences in these parameters between the studied cultivars. A general pattern for the culture is noted; thus, with the increase of stress factors (air temperature, decrease of soil moisture ), water scarcity and cell sap concentration started to increase, at the same time there was a decrease of synthesis of plastic substances.
