Chlorophyll fluorescence intensity of peach leaves in the wilting process

Abstract

The article presents the results of studies to determine the drought resistance of peach cultivars to drought by the water-holding capacity of the leaves and taking into account the chlorophyll fluorescence intensity in the wilting process. It was found that cultivars responded differently to drought. In the studied cultivars, a high correlation dependence of the chlorophyll fluorescence indices of the leaves and the moisture content (0.7-0.9) was traced. On a set of indicators Merkurij cultivar was marked out, it gave away moisture more slowly, restored the leaf surface better, was characterized by better photosynthetic indicators and is promising for cultivation in areas with insufficient water supply.
