Title: A study on soaking and germination characteristics of Fritillaria przewalskii seeds.
Abstract: The effect of soaking Fritillaria przewalskii seeds following after-ripening,and the seed germination characteristics at different temperatures (10,15,20,25,10/20℃ change),were measured in order to provide a theoretical basis for their artificially domesticated cultivation.The 1000-grain weight ranged from 0.72 to 0.82 g.The seeds completed morphologic after-ripening following storage for 45 d at 20℃ and physiological after-ripening after seeds were mixed with sand (sand:seed ratio of 4:1) for 150 d at 5-10℃.The soaking process fitted a Logistic curve,which included sharp soaking,stable soaking and saturated soaking stages.Under dark conditions,the seed germination quality improved with increased temperature and reached an optimum at 15℃ with a germination rate of 90.67% and germination power of 89.33%.However,when the temperature exceeded 15℃,seed germination was significantly reduced and sprout growth was restrained.Temperature was the key condition for seed germination following after-ripening.This suggests that the best time to sow F.przewalskii seeds is under humid and adumbral conditions when the soil temperature is 15℃.
