摘要
采用不同遮阴处理(全光照、73%全光照、55%全光照、30%全光照)研究遮阴条件下白花败酱[Patrinia villosa(Thunb.)Juss.]叶片的形态、解剖结构及生理特性的差异,并探讨其在夏季环境条件下的产量及药用成分。结果表明,随着遮阴程度的增大,白花败酱叶宽、单叶面积、单叶鲜重和叶绿素含量呈增大的趋势,气孔密度、比叶重、可溶性糖、可溶性蛋白质、脯氨酸和丙二醛含量呈降低的趋势,单株产量呈先增后减的趋势,而总皂苷和总黄酮含量则呈先减后增的趋势。综合考虑,在夏季给予55%全光照的遮阴,白花败酱的产量及药用成分含量均较高。
Four levels of artificial shade （100％,73％,55％ and 30％ full sunlight） were used to study the morphological,anatomical and physiological properties of Patrinia villosa （Thunb.） Juss.leaves.The results showed that with the increase of shade density,the leaf width,leaf area,leaf fresh weight and chlorophyll content increased gradually.The stomatal density,specific leaf weight（SLW）,the content of soluble sugar,soluble protein,proline and malonaldehyde decreased.The yield per plant and the content of total saponins and flavonoids increased firstly and then decreased.55％ full sunlight in summer can be used to cultivate Patrinia villosa（Thunb.） Juss due to its high yield and the accumulation of medicinal components.
