摘要
目的 :了解北柴胡生长发育规律 ,为栽培技术制定提供依据。方法 :用植物生长分析方法调查各器官数量。结果 :北柴胡植株由根、根颈、主茎、基生叶、主茎叶、各级分枝和叶、顶花序和各级侧生花序组成 ;1、2级分枝干物质占全部分枝的 93 8% ,3、4级分枝弱小但数量多 ,根 冠比只有 0 19;植株具 3～ 4级侧生花序 ,以 1级和 2级为主要构成部分 ;繁殖器官消耗了全部干物质的 38 1% ;主根长度只有 17 2cm ,与侧根的干物质重约各占 5 0 %。结论 :北柴胡家种时间短 ,野生性强 ,很多性状不符合以根为收获物的要求 ,应加以合理调控和选育。
Objective:To learn the development characteristics of Bupleurum chinense DC. for the cultivation fundament.Method:Mature and intact plant samples of different growing periods are studied by the method of plant growth analysis.Results:The plant organs are composed of root,root crown,stalk,basal leaves,stem leaves,branches and leaves, apical and lateral inflorescences. Dry substance in the branches of the first and second level was 93.8% of that in all branches.Though the branches of third or fourth level were relatively weak,their amount was large.The root-shoot ratio with the value 0.19 was especially low.Lateral inflorescences of third or fourth level were found commonly in the population,but the first and second ones were the majors part.About 38.1% dry substance was used for the development of propagation organ.The length of main root was only 17.2cm,its weight was nearly same as that in the lateral roots.Conclusion:Short cultivated history of B.chinense are still maintained some significant wild characteristics,so they don't accord with the demand of the objective gathering in the root. It may be resolved with artifical regulation and breeding.
