摘要
采用不同浸种温度(30、 60、 100℃)、不同浸种时间(24、 48、 72 h)对粉叶羊蹄甲种子浸种处理后的种子进行发芽试验。结果表明:高温浸种处理方法能够较大幅度提高粉叶羊蹄甲的发芽率,浸种温度较低(60℃)时,粉叶羊蹄甲发芽率较低;浸种温度越高,浸种时间越长,发芽率越高,平均发芽时间越短,100℃浸种72 h后的粉叶羊蹄甲种子发芽率达到41.33%,平均发芽时间为4 d。
Bauhinia glauca(Wall.ex Benth.)Benth.seeds were treated with different seed soaking temperature(30,60,100℃)and different seed soaking time(24,48,72 h)after disinfection treatment.The results show that the high temperature seed disinfection treatment method can improve the g ermination rate of Bauhinia glauca(Wall.ex Benth.)Benth..If the seed soaking temperature is low(60℃),the germination rate of Bauhinia glauca(Wall.ex Benth.)Benth.is lower.The immersion temperature is higher,the soaking time is longer,the germination rate of the Bauhinia glauca(Wall.ex Benth.)Benth.is higher.The germination rate of Bauhinia glauca(Wall.ex Benth.)Benth.which was soaked 72 h in 100℃can reach 41.33%after 4 days.
