| 摘 要： | 对我国乌药自然分布区14个产地采集的乌药种子进行取样观测,分别测定其种子的长、宽、重,并进行播种试验,观测种子的出苗率;分析了乌药种子形态的产地差异、地理变异规律及种子形态对种子出苗率和苗木生长的影响.分析表明:乌药种子形态存在显著的产地差异,种子的大小存在一定的经向变异,种形指数(宽)与经度呈显著的负相关.种形指数与苗期生长有密切的关系.

| Abstract: | The seed length, width and weight of Lindera aggregate from 14 producing areas were measured for investigating their genetic varieties. Experiment on seed germination was carried out to research the relationship between the seed germination and seed characters. The results showed that morphology had difference among areas, and the differences made the seed germination variant. |
