Abstract
Abstract The frequency of a a highly significant relationship between mineral composition and the weight of wheat leaves indicates that leaf growth is substantially affected by the nutritional status of the plant. Nitrogen and calcium have an important influence on the nutritional status at flowering, while the other cations studied had an important influence at post‐anthesis. The regression coefficient for the mathematical models obtained may have a well‐defined value for each physiological stage of the plant or leaf development. Relationships between the mineral composition of wheat leaves and their wheight were most significant at flowering. Due to their close relationship with the yield parameter, i.e. grain, young leaves are suitable organs for this analysis. Eventually, a thorough study of the dynamics of leaf development and the use of leaves from different positions on the stem is suggested.
