摘要
华盖木种子透水性良好,据此推断种子休眠不是种皮的不透水性造成的;种子各部分抑制物质的生物测定结果显示,种子不同部位都不同程度地含有发芽抑制物质;100、300、500 mg·L^(-1)GA_3浸泡24 h可以解除其种子休眠,促进萌发。
The seeds of Manglietiastrum sinicum had good water：absorption and it could be inferred that the seed dormancy was not caused by the water-impermeability of seed coat. The results of biological measurements on components of seeds showed that inhibitory substances with different degrees existed in different seed parts. The seed dormancy could be broken and the seed germination could be accelerated when the seeds were soaked in different GA3 concentrations of 100, 300 and 500 mg·L^-1 for 24 h.
