| Summary: | Production of seed of an onion using mother bulbs is very complicated with many characteristics. First of all is manner of production (two or three annual cycle), sort features, mass of mother bulbs, length of mother bulbs, planting time agro ecological conditions. In order to establish effects of storing temperature and mass of mother bulbs on qualitative and quantitative features we undertake these experiments. Investigation conducted using onion bulbs (old domestic sort - Prizrenski pogačar) with mass of 5-25g and 50g. Bulbs were stored 90days before planting at the temperature of 4-6°C, 10-12 °C and 16-18°C. Storing temperature exert influence on number of floral stalks, time of flower formation, yield and quality of seed. High (16-18ºC) and low (4-6°C) temperature inhibit or retarded formation of floral primordial. Optimal temperature was 10-12ºC. Planting of larger bulbs produce greater number of floral stalks in comparison to small bulbs. Influence of vernalization temperature on number of floral stalks on bulbs with larger mass was insignificant. . |
