摘要:
对怀菊花(Chrysanthemum morifolium Ramat.)脱毒苗与非脱毒苗的生长发育、产量和品质进行了比较研究.结果显示:脱毒株系的株高、冠幅、分枝数、叶绿素含量、产量和有效药用成分含量均高于非脱毒苗,其中脱毒株系YD5J6最优,与非脱毒株系相比,产量增加25.17%,绿原酸、木樨草苷、3,5-O-二咖啡酰基奎宁酸的含量分别提高2.784%、19.374%和25.662%.脱除病毒可显著地改善怀菊花的生长发育,使其光合能力增强、产量提高、品质改善.筛选出的高产优质脱毒株系对怀菊花脱毒种苗的规模化生产及大面积推广应用具有重要的意义.
In this study,the growth and the flower yields and quality were detected among the TAV-free and the control seedlings.The results showed that the plant height,crown width,branch number,chlorophyll contents,flower yields and effective medicinal ingredients in the TAV-free strains were higher than those in the controls.YD5 J6 was the best among the TAV-free strains as indicated by the flower yields,contents of chlorogenic acid,luteoloside,3,5-dicaffeoylquinic acid increasing by 25.17%,2.784%,19.374% and 25.662% compared to the controls,respectively.Removing TAV could obviously enhance the growth and photosynthetic capacity of C.morifolium Ramat resulting in increase of flower yields and quality.The results are of great significance for the large-scale production and application of C.morifolium Ramat.
