【摘要】 分别对不同来源的三叶木通种子的千粒重,种子长、宽、高进行了测定,并进行了方差分析,结果显示不同来源的种子差异显著(p<0.01);不同条件种子萌发实验结果显示其发芽率有极显著性差异(p<0.01),发芽率大小为:常温沙藏>4℃冷藏>室温搓洗>室温未搓洗,适度的沙藏有利于三叶木通的发芽。对风干种子进行发芽试验,并使用TTC法测定其活力,测试样全部未发芽且均失去活力,说明三叶木通种子属于脱水敏感性种子。更多还原

【Abstract】 The 1000-seed weight,length,width,height of seed from different places were measured. The data were analysis by analysis of anova.The result showed that the diversity had significant differences between different places(p<0.01);The test of different germination conditions results showed that germination rate between the different germination conditions were significantly different(p< 0.01).Germination rate as follow:room temperature in sand>4℃refrigeration>scrub>not scrub.That the seeds were save in the sand was conducive to the germination of seed;The germination rate and activity of seeds of air-dried were tested.The result showed that the seed all lost activity. This showed that the seed was very sensitive to water.更多还原
