摘要

This study conforms the hypothesis that elite maize inbred lines with erect top leaves and hybrids, in which they are included as parents, have a dominant property of an efficient photosynthetic-fluorescence model and that as such are successfully used in breeding and modern production technology of hybrid seed and commercial maize. The displayed results on the erect position of the top leaves, increased density, the dynamics of grain dry-down during the maturation period, seed quality of hybrid andcommercial maize and photosynthetic and fluorescent parameters: the temperature dependence of the delayed chlorophyll fluorescence intensity, the Arrhenius criterion for the determination of critical temperatures (phase transition temperatures) and the activation energies, show that properties of observed inbreds and their maize hybrids are based on positive effects and the nature of conformational and functional changes that occur in their thylakoid membranes and other chemical structures of grain andleaf tissues. The present study also encompasses analyses of other relevant breeding and seed properties of observed prestigious maize inbred lines and maize hybrids derived from them (dependence of their yields on the density, and quality of commercialmaize over the kernel structure and chemical parameters).
