SEED GERMINATION OF SWITCHGRASS (PANICUM VIRGATUM L.) DEPENDING ON ITS BIOLOGICAL PECULIARITIES

Abstract

The research results of some peculiar aspects of millet seed formation depending on its biological peculiarities are presented in the paper. It has been found out that seed germination does not depend on its maturation state at harvest time which does not limit the choice of a seed harvesting practice - direct combining or two-stage method. A year of crop vegetation and groups of cultivar maturation had a significant effect on seed germination. The lowest germination was (37%) recorded when seeds were harvested from the plants of the first vegetation year and the cultivars of average-early, average-late, late and very late groups of maturation. Very late-yielding cultivars had the lowest germination - 17%.
