摘要
比较 3种打破滇青冈种子休眠方法的结果表明 ,经 4 0℃处理后的效果最好 ,发芽率达 74 .5 %。 10 0mg·L-1的赤霉素浸种处理的次之 ,发芽率为 70 .2 %。种子种皮切伤和去除种皮后 ,发芽率增大 ,分别为 96 .0 %和 95 .0 % ,并提早 5d萌发。种子抑制物质实验的结果显示 。
The efficiencies of three treatment methods for breaking dormancy seed of Cyclobalanopsis glaucoides were compared. The treatment with 40℃ was the optimum for breaking dormancy of seed, and the germination rate was 74.5%. The seeds soaking in 100 mg·L -1 GA 3 also promoted the seed germination (70.2%). Incisive and removed seed coat were effective in raising the germination rates (96.0% and 95.0% respectively). The germination time was shortened by 5 d in comparison with control.
