山茱萸种子种胚的石蜡切片表明其种胚已完成形态后熟,具有完整的子叶、胚轴,且有胚芽原基出现。山茱萸种子钳去两端种皮,以不伤胚为度,在35℃水中浸泡7天,发芽率可达58%,而在同样的条件下,未钳去种皮的种子不萌发。用皿唑定量法测得山茱萸休眠种子种皮中含有发芽抑制物,未发芽的种皮中含量高于发芽的。 Paraffin sections of the seed of the dogwood seed showed that the seed embryos had completed morphological ripening, had intact cotyledons and hypocotyls, and germ primordia appeared. Cornus seeds were tweezed to both ends of the seed coat to injure the embryo for the degree of soaking in water at 35 ℃ for 7 days, the germination rate was 58%. Under the same conditions, the seeds without the seed coat were not germinated. The content of germination was found in the seed coat of dormant seeds of Cornus officinalis Sieb.
