THE EFFECT OF THE FIRST FERTILE FLOOR ON QUALITATIVE - QUANTITATIVE PROPERTIES OF SOYBEAN SEED

The aim of this study was to determine the effect of height of the first fertile floor on the qualitative and quantitative characteristics of soybean seeds. For qualitative traits the focus was on the energy of germination and seed germination of the studied genotypes investigated per soybean plant and the first fertile floor of the plant. Results of research indicated that there were significant differences between genotypes observed by morphological characteristics (plant height, height of first fertile floor, number of fertile floors, number of pods and seeds, seed weight, etc.) as well as qualitative properties (energy of germination and seed germination). Cultivar Gorstak, with genetically incorporated height of the first fertile floor (12.38 cm), was superior to other two genotypes. A similar trend was found in other morphological analyses. Based on energy of germination and seed germination of all fertile floors per plant, there were no significant differences between soybean genotypes. However, of paramount importance are the established values of these parameters relevant to the first fertile floor. Cultivar Gorstak had significantly higher energy of germination (90.46%) and total germination (91.00%) compared to the other two genotypes.
