| 摘 要： | 采用不同方法对猪屎豆种子进行处理,并测定了种子的硬实率、吸水率和发芽率.结果表明:猪屎豆种子有较高的硬实率,砂纸摩擦5 min可显著提高种子的吸水率；砂纸摩擦1～7 min均可提高种子的萌发率,摩擦5 min的发芽率达36％,而未摩擦种子发芽率只有11.3％.丙酮处理种子1、2、3、4h不能提高种子的发芽率,时间越长,种子的发芽率越低；过氧化氢处理对种子的催芽没有显著的效果；摩擦后种子在室温(10 ～27℃)、15、25、30、35℃条件下均能萌发；光照对种子的萌发没有显著的影响,说明猪屎豆种子是中光种子.

| Abstract: | Hard seed percentage,water absorption rate and germination rate of Chrotalaria pallida seeds had been determined after different physical or chemical treatments.Results:Chrotalaria pallida seeds had relatively high hard seed percentage;sandpaper rubbing for 5 minutes significantly increased water absorption rate;sandpaper rubbing for 1-7 minutes promoted seed germination rate,up to 36% for 5min rubbing,whereas the germination rate of un-rubbed seeds was merely 11.3%.Acetone treatment of the seeds for 1-4hou... |
