This study conforms the hypothesis that there are elite maize inbred lines and hybrids with erect top leaves, which have a dominant property of an efficient photosynthetic and fluorescent model, that is successfully used in modern breeding programmes and the production of hybrid seed and commercial maize. This statement is supported by the displayed results on the erect position of the top leaves, the dynamics of grain dry-down during the maturation period and photosynthetic and florescence 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. The presented results show that properties of observed maize inbreeds and their hybrids are based on the nature of conformational and functional changes that occur in their thylakoid membranes and other chemical structures of tissues of grain and intact leaves, as well as, on positive effects in maize breeding.
