Purpose. Developing a method for determination of the laboratory seed germination that could reduce the biological dormancy period and, accordingly, increase the intensity of germination.
Methods. Laboratory, measuring and weighing, mathematical and statistical.
Results. Cooling switchgrass seeds at a temperature of 10°C for 7 days on average for three years did not lead to a decrease in germination energy and germination compared to cooling for 14 days. These indexes were almost the same and amounted to 74 and 76%, 73 and 75%, respectively. There were no significant deviations in germination energy and seed germination over the years of research as affected by duration of the cool period. The production test of the developed method, carried out in the accredited control and measuring laboratory, confirmed the obtained in the laboratory results.
Conclusions. Seed germination by an improved method, when pre-cooling is carried out for 7 instead of 14 days and counting of germinated seeds on 15th day instead of 20th, has reduced the time to determine germination by 13 days without reducing the quality of analysis. It is advisable to determine the 1000-seed weight in one of three ways, but the most accurate is the third way, i.e. counting the seeds in 10 repetitions.
