SOME ANATOMICAL CHARACTERS OF STEM AND SPIKE IN DIFFERENT WHEAT GENOTYPES

Resistance of plants has a great importance in cultivation programs and more dependent on the anatomic construction stem and spike. Investigated show the plants sustainability depends of the development of mechanical tissue (sclerenchyma) and vascular bundles on the stem and spike (Jankovic, 1966). There are investigated some anatomical characters of stem and spike, where as based on the data from the literature, those organs are playing very important role on the fruit production. On the cross section of the stem (six genotypes) and spike (seven genotypes) are analyzed: number and surgace of vascular bundles, number of chlorenchyma bands, number of sclerenchymal cell rows. Archieved results shows that those parameters have varued subject to the genotypes and internodes position on the stem, respectively spikelet’s on the spike.
