摘　　要：探究浙江省野生蜡梅种子的生物学特性,提高种子萌发率,为其保护和利用提供参考。研究结果表明:野生蜡梅种子千粒重约为396.98 g,含水量约为15.66%,生活力约为91%。萌发抑制物主要存在于种仁中,醇溶性活性强于水溶性物质,有吸水性障碍的坚硬种皮和萌发抑制物使种子最高发芽率不能达到种子批活力的数值,并影响了其出苗整齐度。种子进行刺破种皮后浸水处理能改善种子结构,有利于种子萌发。To investigate the seed biological character/stics of wild Chimonanthus praecox of Zhejiang Province and improve germination rate, which provided the reference for conservation and utilization. The result showed that the 1 000-seed weight was about 396.98 g, water content of the seed was about 15.66%, the viability was about 91%. The germination inhibitor of Ch. praecox mainly exist in kernel, the inhibitory methanol crude extracts was stronger than aqueous crude extracts. The exist of dense and hard seed coat and germination inhibitor make the highest seed germination rate is less than the seed lots viability and also influence the germination uniformity. Seed of soaking after pricked can improve the seed structure and in favor of germination.
