Abstract

This study was investigated seed germination of Rheum undulatum L. depends on storage temperature (-20, $5^{\circ}C$ and room temperature), germination temperature (5, 15, 25 and $40^{\circ}C$) and a soaking treatment (no soaking, 2 days and 4 days). There was not much difference from the germination rate of R. undulatum L. in storage temperature conditions for 8 weeks. The highest of germination rate occurred over 80 percentage at $25^{\circ}C$. 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.
