Abstract
In three series of experiments conducted in the years 2004–2006 germination of seeds of three naked oat cultivars (Akt, Cacko and Polar) and two hulled oat cultivars (Bajka and Skrzat) was investigated at the following temperatures: 10, 15, 20 and 25°C. On the basis of observations collected at intervals of 24 hours germinabilty of the seeds, mean germination time and dynamics of germination were estimated. In most cases the germinability of seeds exceeded 95%, sporadic fluctuations in value of this index were caused by seasonal variability, evaluation date and conditions during seeds incubation. The effect of various temperatures during seeds incubation on germination process was more long-lasting in the hulled oat cultivars as compared to the naked ones. The results of final evaluation of germinability of seeds, mean germination time and dynamics of germination carried out on the 8th day as well as on the 10th day of seeds incubation were similar. This fact points to a possibility of evaluation of germinability in naked oat cultivars in 8-days period. The process of germination of naked and hulled oat cultivars’ seeds, which were incubated at 25°C directly after harvest showed deeper dormancy of the hulled cultivars’ seeds as compared to the naked ones.
