摘要(Abstract):

目的:研究不同寄主对百蕊草生长发育和药材活性成分含量的影响,筛选百蕊草优良寄主。方法:测定寄生于不同寄主的百蕊草的形态指标和药材活性成分含量,运用指数和法对寄主进行综合评价。结果:寄主可以显著促进百蕊草株高、单株重、茎粗、叶面积、种子数和吸器数量的增加及根重/茎重比的降低。不同寄主对百蕊草生长的促进和药材各活性成分含量的影响存在显著差异。综合得分鼠曲草最高(37分),其次是白茅和夏枯草(36分),它们均可作为百蕊草药材生产的优良寄主;小麦(25分)和假俭草(17分)得分较低,不适合作为百蕊草药材生产的寄主。结论:寄主可以显著促进百蕊草生长发育,寄生于不同寄主的百蕊草,其生长发育和药材各活性成分含量存在差异。鼠曲草、白茅和夏枯草均可作为百蕊草药材生产的优良寄主;小麦和假俭草不适合作为百蕊草药材生产的寄主。
Objective: To study the influence of host species on growth and development and active component content of Thesium chinense.Method: Plant morphology and active component content of T.chinense grown with different hosts were measured.The hosts were evaluated by using index-sum method.Result: Hosts significantly promoted the growth of T.chinense by increasing height,per plant weight,stem diameter,leaf area,the number of seed and haustorium,and decreased RW/SW ratio compared to without host treatment.Considerable differences existed among the effect of different host species treatments.Synthetical evaluation score of Gnaphlium affine was the highest(37),followed by Imperata cylindrical and Prunella vulgaris(36).It is suggested that they were superior hosts for T.chinense.But the scores of Triticum aestivum(25) and Eremochloa ophiuroides(17) were lower,so they were unsuited hosts for T.chinense.Conclusion: Hosts significantly promoted the growth of T.chinense.Considerable differences existed among the growth and development of T.chinense grown with different hosts,as well as active component content.Gnaphlium affine,Imperata cylindrical and Prunella vulgaris were superior hosts for T.chinense.While Triticum aestivum and Eremochloa ophiuroides were unsuited hosts for T.chinense.
