Morpho-anatomical analysis of spike of wheat genotypes

Abstract

The goal of the paper is to find, by means of an analysis of morpho-anatomical characteristics of the spike of tetraploid and hexaploid wheat genotypes, characteristics which most strongly influence the differences in yield. The hexaploid genotypes have a significantly longer spike, with a greater number and mass of grain/spike. For both groups, a normal distribution of the number and mass of grain/spikelet of a main shoot spike is notified. An analysis shows that the hexaploid genotypes have a greater cross section rachis area, and a greater number of the smaller vascular bundles, in comparison to the tetraploid ones.
