| 摘 要： | 用NaOH、H2SO4、KNO3、摩破种皮和低温处理等方法对假俭草种子进行萌发试验研究,结果表明:以50 g/L的NaOH处理15 min效果最好,发芽率,发芽势和发芽指数分别为97.5%,72.5%和45.4%,分别比对照高77.5%,72.5%和43.1%,发芽时间较对照提前4 d;其次为摩擦处理,该处理的发芽率可达90%,H2SO4,KNO3和低温处理的最高发芽率分别是72.5%,47.5%和27.5%,因此,不同处理之间发芽率差异显著(P<0.05)。

| Abstract: | Centipedegrass seeds were treated with NaOH,H2SO4,KNO3,rubbing and low temperature and the results indicated that the best treatment was to treat the seed with 50 g/L NaOH for 15 min,and the germination rate,germination vigor and germination index were 97.5%,72.5% and 45.36 respectively(increased by 77.5%,72.5% and 43.10%).Rubbing treatment took the the second place and the germination ratewas 90%.The germination rates under treatment H2SO4,KNO3,low temperature were 72.5%,47.5% and 27.5% respectively.The difference among treatments were significant. |
