| 摘 要： | 用不同浓度的GA3、NAA和CTK等3种外源激素处理当归大、中、小苗,研究种苗大小和外源激素对当归的抽薹率、产量及产量构成的影响。结果表明,未经外源激素处理的小苗抽薹率显著低于其他处理,抽薹率为14%;未经外源激素处理的中苗是主根长、收获株数和产量的最优处理,但种苗大小和外源激素对当归主根长影响差异不显著;50 mg/L CTK处理可促进大苗根部的膨大和伸长生长,有利于根部干物质的积累;50 mg/L GA3处理有利于中苗侧根数的减少。 |
| 关 键 词： | 当归 种苗大小 外源激素 抽薹率 产量 |

| Abstract: | In this study,different concentrations of GA3,NAA and CTK on Angelica sinensis large,medium and small seedling were introduced for study the effects of seedling size and exogenous hormones on Angelica sinensis bolting rate,yield and yield component factors.The results showed that the optimal treatment of Angelica sinensis bolting rate is small seedling,up to 14%,which was significantly lower than other treatments.The optimal treatment of Angelica sinensis root length,harvest number and yield is medium seedl... |
