不同处理方法对百脉根种子发芽的影响

Effects of Different Treatment Methods on Seed Germination of Lotus corniculatus

通过试验探讨了不同温度、pH和湿度处理对百脉根种子萌发的影响。结果表明:不同温度、pH和湿度处理对百脉根种子的萌发均有显著影响。百脉根种子在24℃左右时发芽率和发芽指数最高,分别为64%和24.0;pH为6时其发芽率和发芽指数最高,分别为64%和24.7;当湿度为40%时,百脉根种子发芽率和发芽指数最高,分别为72%和25.0。

The influences of different temperatures, pH and humidity on the characteristics of Lotus corniculatus are studied. The result shows that different temperatures, pH and humidity have significant influences on the germination characteristics of Lotus corniculatus. The germination rate and germination index of Lotus corniculatus seed performed best under 24 ℃ are 64% and 24.0, respectively; The best pH value is 6, under which the germination rate and germination index are 64% and 24.7, respectively. When the humidity is 40%, the Lotus corniculatus seed germination rate and germination index are 72% and 25.0, respectively.
