| 摘 要： | 在马铃脱毒试管苗培养过程中 ,对其生长发育特性进行观察及对内源激素进行测定 ,结果表明 :在培养的 30d内 ,随着植株高度、数、根长、根数、茎叶干重及根干重的不断增加 ,内源激素也呈现有规律变化 ,ABA在培养至 2 0d达峰值 ,以后均保较高含量水平 ;CTK在培养前 2 0d含量基本不变 ,2 0～ 30d含量剧增 ;而IAA在培养的 30d内 ,含量是不断增加的

| Abstract: | During the course of virus free plantlet culture of potato,the dynamics of endogenous hormones was investigated.Plant height,number of leaves,length of roots,number of roots,dry weight of stem and leaves,and dry weight of roots were increased with culture.At the same time,the endogenous hormones changed with plantlet growth.The content of ABA reached peak when virus free plantlet had been cultured for 20 days,then the content held high for another 10 days.The content of CTK was low for 20 days,but it increased quickly form the 20th to 30th day.The content of IAA increased continuously in the course of culture. |
