EFFECT THE STRONTIUM SALTS FOR BIOMETRIC AND FLUORESCENT INDICATORS AND WHEAT
fluorescent characteristics of photosynthetic pigment complexes isogenic lines of wheat. "Mironovskaya 808" salts of strontium were investigated. It is shown that incubation of wheat seedlings in solutions SrCl2 inhibited the growth processes, reduce the rate of photosynthesis. In the post-stress period of photosynthesis increased. Analysis of chlorophyll fluorescence induction curves all grades (Rht 9, 13, 17) showed that in the early stages of the toxic effect of Sr in the concentrations studied is manifested not only in the suppression of PSII electron transport, but also to reduce the degree of energization of photosynthetic membranes. Initial development processes Sr toxic effect associated with decreased efficiency of light reactions of photosynthesis.
