The results suggest that the genotype and the nutrient supply had a considerable influence on both the yield and the physiological traits, while the growing season modified the parameters in a significant manner. The results proved that the chlorophyll content and leaf area index had a direct influence on the yield; varieties developing larger leaf area and leaf chlorophyll content had higher yields even in different seasons, but the yield was significantly influenced by the decline in the chlorophyll content after flowering. It could be concluded that studying the chlorophyllcontent and leaf area values simultaneously during the more important phenological phases (especially from flowering to the early period of grain-filling) makes it possible to predict the yield from the trends. 收起
