종자 처리조건에 따른 종대황 발아 특성

초록

This study was investigated seed germination of Rheum undulatum L. depends on storage temperature (-20, 5℃ and room temperature), germination temperature (5, 15, 25 and 40℃) and a soaking treatment (no soaking, 2 days and 4days). There was not much difference from the germination rate of R. undulatum L. in storage temperature conditions for 8weeks. The highest of germination rate occurred over 80 percentage at 25℃. When R. undulatum L. was soaked with tap water for four days, the average values of germination velocity and germination day were represented of 1.7 ea/day and 1.68 days. These results may help our understanding of variations in germination characteristics for R. undulatum L. seeds treated under various germination conditions.
