SEED SOWING VALUE AND RESPONSE TO DROUGHT STRESS OF ORGANIC AND CONVENTIONAL OAT (Avena sativa L.) SEEDS DURING 5 YEARS OF STORAGE
Journal Title: Acta Scientiarum Polonorum – Agricultura - Year 2016, Vol 15, Issue 3
Abstract
Abstract. Due to progress of ecological farming the breeders and farmers need to know how to store ecological cereal seed material. Investigations on the seed storage value of ecological and conventional seeds were performed on naked and hulled oat during 5 years of storage in a granary and long-term store. There were analysed germination capacity, mean germination time, vigour by the growth test according to ISTA method and response to drought stress. It was found that germination capacity and vigour were lowest for the organic seeds of cv. Polar stored in a granary. In the hulled cv. Krezus degradation process was delayed. In case of long-term storage, seed value was retained irrespective of the cultivar or method of cultivation. The highest response to drought stress occurred in organic seeds of cv. Polar taken from a granary. The response to drought stress of the hulled cv. Krezus was lower irrespective of method of cultivation.
