Abstract
The area of leaf blades of winter wheat culm of the Sakwa variety, cultivated in the years 1998–1999 on the degraded chernozem with different forecrops, was measured with the use of the destructive method. The results indicate remarkable variation of the empirical and indirect traits, caused by the weather conditions. The influence of the forecrop groups on dimensions of the wheat culm in the full ear stage was not significant. The indirect traits should be considered a good additional source of information about the leavage of the culm, because they allow for the comparison of relationnships between two traits in various conditions. The values of the phenotypic correlation coefficients between any of the empirical and indirect traits of a single culm were, in general, high. The phenotypic correlation coefficients were, in general, high, because three of them (between empirical traits) and one of them (between indirect traits) exceeded 0,75. The majority of the Pearson correlation coefficients were highly significant. The distribution of the fresh mass per 1 cm2 of leaf blade differed between erectoidal and hanging leaves. In the hanging leaves the part of a leaf near the bending point had the highest weight per unit (1cm2). In the erectiodal leaves the leaf blade weight per unit decreased in subsequent parts, beginning from the base. The direct comparison of contribution of the two structural components to the total area of the culm leaves indicates that average leaf area prevailed in that context because its contribution was 78,8%. The number of leaves per blade had weaker influence, and its contribution was 21,2%. Leaf area index of the wheat stand was determined mainly by the total area of leaf blades of a culm; the contribution of that component was 98,3%. After taking into account the density of culms in the full ear stage (developed flag leaves) the contribution of that element should be described as very small because its value was only 1,7%.
