摘要
厚荚相思种子是硬实性种子,本试验采用浓硫酸与沸水浸泡处理方法打破其休眠。结果表明,浓硫酸25min+沸水浸泡20min的处理方法最好,萌发率可达95%;浓硫酸与沸水浸泡相结合的处理方法对种子的萌发率、萌发整齐度均优于单独用浓硫酸处理或沸水浴处理,而异状萌发率、腐烂率也较低。该处理方法对提高其它相思类的种子萌发率有参考价值。
The seeds of Acacia crassicarpa were hard and solid. In this experiment the treatments of thick vitriol and hot water were used for breaking seed dormancy. The results indicated that the highest germination rate of 95% occurred by the treatment of thick vitriol for 25 min with boiled water for20 min, which was better than the treatment of thick vitriol or hot water in germination rate and regularity, and which was also lower in abnormal germination rate and putridity rate. The method was of great value for promoting germination rate of seeds in other species of Acacia.
