摘　　要：以苦参种子为试材,研究不同浓度的水杨酸溶液和不同温度对不同产地苦参种子发芽的影响,以期找出促进种子发芽的较佳方法。结果表明:高锰酸钾消毒后,种子的烂种率降低;赤峰种子在温度为30℃、水杨酸浓度为150mg/L时发芽率最高,卢氏种子在温度为25℃、水杨酸浓度为120mg/L时发芽率最高。2个品种中河南卢氏种子的发芽率高于内蒙古赤峰种子。Taking Sophora flavescens seeds as material,effect of different temperature and concentrations of salicylic acid solution on seed germination were studied, in order to find a better method to promote the germination. The results showed that rotting rate of seeds decreased after potassium permanganate disinfection; Chifeng seeds＇ germination rate was the highest at a temperature of 30℃ and concentration of salicylic acid 150 mg/L, and Lushi＇s was at 25℃ and 120 mg/L,respeetively. The seeds germination rate of Lushi from Henan was higher than that Of Chifeng from Inner Mongolia.
