| 中文摘要: |
| 为探讨不同化学试剂对翅荚决明（Senna alata L援）种子发芽率和幼苗生长的影响，用 4 种不同浓度的化学试剂（KNO3、GA3、KMnO4和 NaOH）分别处理种子。结果表明：0.5-4.0 g/L KMnO4和 0.05-0.4 g/L GA3浸种显著促进种子萌发，加快幼苗生长速度，其中以 0.1 g/L GA3和 4 g/L KMnO4浸种 24h 效果最佳，是解除翅荚决明种子休眠、促进幼苗生长的有效措施；1-8 g/L KNO3浸种显著促进了种子萌发，但对幼苗生长影响不明显；而5-40 g/L NaOH 浸种明显抑制种子萌发和幼苗生长, 且随着浓度增加，抑制作用明显增大。 |
| 英文摘要: |
| The research was carried out to study the effects of four kinds of chemical reagents (KNO3, GA3,
KMnO4 and NaOH) on seed germination and seedling growth characteristics of Senna alata L. The results indicated
that all concentrations of KMnO4 and GA3 promoted the germination and seeding growth of S. alata L., and 0.1g/LGA3
and 4g/L KMnO4 were the most effective reagents. All KNO3 concentrations promoted the germination, but the growth
of seedlings were not affected. The germination process and shoot height were depressed under different
concentrations of NaOH, the larger the concentration was, the more severely the seed germination and seedling
growth characteristics of S. alata L. influenced. |
