Abstract
This study confirms 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 hybrid seed and commercial
maize. This statement is supported by the displayed results on the erect 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 inbreds and their hybrids are based on the nature of
conformational and functional changes that occur in their thylakoid membranes
and other chemical tissues structures of grain and intact leaves, as well as,
on positive effects in maize breeding. Moreover, other relevant significant
breeding and seed production properties (commercial maize quality over grain
structure, physical and chemical parameters) of maize inbred lines and their
hybrids were analyzed in the present study.
