摘要
目的明确滇重楼种子适宜采收期,为滇重楼的科学采种提供参考。方法通过室内分析、发芽和播种试验,分别比较了两个滇重楼种植基地采收的橙色、红色和深红色外种皮种子的大小、千粒重、发芽率、成苗率及种苗农艺性状。结果深红色外种皮种子大小和千粒重的数据高于其它两种颜色外种皮种子;深红色外种皮种子的发芽率和成苗率明显高于其它两种颜色外种皮的种子,且差异有统计学意义;深红色外种皮种子繁殖种苗的主要农艺性状优于其它两种颜色外种皮种子的种苗。结论滇重楼种子的最适宜采收期为果实裂开后外种皮为深红色时。
Objective To study the best harvest time of Paris polyphylla var. yunnanensis seeds. MethodS Seeds of orange testa,red testa and dark red testa were harvested respectively in two planting bases of Paris polyphylla vat. yunnanensis ,and their size, 1000-grain weight,germination rate,seedling rate,and seedling agronomic traits were determined in laboratory. Results Dark red testa seeds were bigger in size and heavier than other color seeds, their germination rate and seedling rate was significantly higher as well, seedling sprouted from dark red testa seeds showed the best agronomic traits. Conclusion It is the best time to harvest seed of Paris polyphylla var. yunnanensis when its testa color become dark red.
