摘要: 关龙胆系中药材商品名,原植物为龙胆属三种植物(东北龙胆、粗糙龙胆、三花龙胆)。本文对关龙胆从花蕾至果实发育全过程进行了观察与讨论。明确了它们有15天左右的花期相遇,可进行杂交;繁育行为属兼性自交;花期较长导致种子胚发育不整齐。

关键词: 龙胆属, 开花, 结实, 生物学特性

Abstract: Guanlongdan is a commercial name of Chinese drug.The original plants contain 3 species of Gentiana(G. manshuricaG. scabraG. triflora).The developmental process from flower bud to fruit was observed and discussed in this paper.It was clear that the 3 specise of Gentiana are able to hybrize each other.the breeding behavior belongs to facultative selfing and the developing of the seed embryo is irregular.
