摘要
Seed germination characteristics of Dendrobenthamia capitata var.emeiensis(Fang et Hsieh) Fang et W.K.Hu were studied in different conditions.The seeds could germinate normally both in darkness and light conditions with no difference on germination percentage.Temperature and GA3 had significant effects on the seed germination.Germination percentage was the highest(21.0%) under 25 ℃ condition.The 200 mg·L-1 GA3 soaking for 24 h was better for the seed germination with a germination percentage of 34.5%.
