北柴胡移栽试管植株生长关键期主要遗传参数分析

Study on Main Inheritable Parameters of Test-tube Plants Population of Bupleurum chinense in Different Growing Periods

目的:确定北柴胡移栽试管植株群体的生长状态及药材品质。方法:植株返青后标记植株并定期测量植株的株高、分蘖数、叶片数等田间性状,利用统计学方法对所测数据进行分析。结果:北柴胡移栽试管植株在营养生长期、花期、种子成熟期各性状的标准差和相对标准偏差均不大,植株群体生长一致,整齐度高,变异性低;根长、根重的相对标准偏差小,平均根长、根重较普通种子植株有优势,有效成分含量高,药学性状优良,药材质量均一;植株的分枝数多、有效果序数大,种子产量高;植株的冠重大,经济价值高;移栽试管植株在不同生长期各性状间的相关性与普通种子植株有一定的差异。结论:北柴胡移栽试管植株具有优良的植物学和药学性状。

Objective： To determining the growth status and medicine quality of test-tube plants of Bupleurum chinense.Methods： Measuring the field characters of the labeled plants at fixed period after turning green,such as plant height,number of tiller,number of leaves.Using statistical methods to analyse the measured data.Results： Each genetic characters standard deviation and relative standard deviation are all smaller at vegetative growth phase,bud forming phase and seed ripening phase.The test-tube plants population of Bupleurum chinense grows consistently.Its uniformity is higher,variability is low.Bupleurum chinense length and weight of root relative standard deviation are all low.The average root length and weight are more predominant than ordinary seed plants.The roots have high content of effective components.Bupleurum chinense population pharmaceutical character is excellent,The medicinal quality is consistent.The number of branch stem and effective fruit bunch is bigger,The seed production is higher.The aerial part yield is large,The economic value of test-tube plants of Bupleurum chinense is higher.The correlation between each characters of test-tube plants of Bupleurum chinense is different from the ordinary seed plants in diferent growing periods.Conclusion： The botanical and pharmacognostic characters of test-tube plants of Bupleurum chinense are excellent.
