Abstract
Growth analysis and ecophysiological research are aimed at investigating the agronomic and ecophysiological regulation of yield formation and at comparing the agronomic and environmental responses of maize hybrids at the plant stand, individual plant, and plant organ levels. The experiments will take the form of bi- and multifactorial small-plot field trials, some of which are part of long-term experiments in progress for several decades. The effects of the treatments in these experiments result in significant differences in yield, but little is yet known of the agronomic, ecological and physiological factors that cause these differences or of the interactions between the various factors. Growth analysis is an ideal method for studying the independent and interactive effects of different factors and, when supplemented by ecophysiological analyses, for discovering the causes of genotypic differences in agronomic responses. Great emphasis will be placed in the present project on ecophysiological analyses, especially on the investigation of correlations between the yield and the growth of maize plants, between the yield and photosynthesis, between the N supplies to maize plants and the photosynthetic yield, and between the PAR and the yield. Scientific cooperation with Prof. Roderick Hunt will play an important part in the ecophysiological studies and growth analysis. Three junior scientists will be working for their PhDs within the framework of the project. A book on growth analysis and yield formation and papers in scientific journals are planned as the result of the project.
