Varietal particularity of morphometric parameters and activity of alcohol dehydrogenase of winter wheat (Triticum aestivum) seedlings during waterlogging

Abstract

It is shown that the waterlogging of seedlings of different winter wheat varieties in model conditions usually leads to a lengthening of the first leaf, which is accompanied by slower growth of the roots and which indicates the apparent tolerance of seedlings to such stress. During waterlogging the activity of alcohol dehydrogenase in the roots of seedlings increases in variety-specific manner by increasing the expression level of its both constitutive and inducible isoforms. It is suggested that the total activity of alcohol dehydrogenase and the expression level of genes encoding some of its isoforms, can be used to identify cultivars of winter wheat possessing high true tolerance to waterlogging.
