Intravarietal variability of the structure of correlations of yield components in oat and barley plants

It is shown that intravarietal differences in level of aluminum tolerance of oat and barley plants affect the formation of yield components under nonstress conditions. Species specificity is noted in a change in the structure of correlations of the studied traits in these plants. Increased aluminum tolerance of plants is related to breakdown of many correlations characteristic for nontolerant plants.
