ABSTRACT

Results of microplot trails have shown that under the influence of ions of heavy metals there is a considerable reorganization of system of interrelations of elements of plant productivity in oats (Avena sativa L.) and barley (Hordeum vulgare L.). In the majority of variants of treatment of plants with heavy metals the structure of correlations between elements of yield structure of plants characteristic for normal conditions is collapsed. Influence of

intravarietal distinctions on aluminum resistance level of plants of cereal crops on system of correlations of elements of yield structure is found out. As a whole for all studied metals resistant varieties of cereal crops kept coordination of growth processes under stressful conditions in a greater degree than varieties sensitive to stressful influence. It is shown that fluctuations of level of correlations between elements of yield structure in oats and barley can indicate intravarietal heterogeneity on separate parameters. In two series of study it was showed specie-specificity in change of structure of correlations of the investigated parameters in barley and oats.
