VIABILITY CHARACTERISTICS AND PHYSIOLOGICAL BEHAVIORS IN CABBAGE SEEDS IN DEPENDS ON STAGE OF MATURITY
2008, 9 (4) p. 765-770
The main purposes of the present study were to establish the changes during different stage of maturity and development of cabbage seed as well as earliest behaviors of viability and harvesting data. The experiments were carried out with two typical Bulgarian cultivars Balkan and Ditmarsko ranno. Samples of seeds in different days after fl owering – 30, 40, 50 and 60 days were analyzed. The physiological parameters and viability and vigor were investigated. The weight of one seeds was highest between 40 and 50 days. The primary germination was observed in seed harvested in 30 days, but the stability one was registered on 60 day. The intensity of respiration and activity of enzyme peroxides changed during seed development and maturity.
