The Peach resistance to stress factors of humid Russia subtropical

Abstract

The article presents the results of many years of research to identify the variety of peach stability including functional estimation of peach plant on complex water regime parameters (quantities of water deficit, water-holding capacity, the thickness of the leaf blade) and the pigment composition (chlorophyll a and b and carotenoids). These parameters characterized by high lability and high responsiveness to the action of many abiotic factors (temperature, humidity, and so on), and therefore, carried out a study to identification of diagnostic indicators, which are closely connected with the water status of the peach culture.
