| 摘 要： | 实验以早熟马铃薯品种费乌瑞它(Favorita)和中熟品种夏波蒂(Shepody)的脱毒试管苗为材料,诱导结薯,研究离体块茎在休眠与萌芽过程中不同时期的内源激素GA3,KT,IAA和ABA含量的变化。结果表明:①KT,GA3,IAA,三种激素含量随着休眠的解除呈明显上升趋势;②ABA的含量甚微,品种费乌瑞它仅在第一时期及品种夏波蒂仅在第一和第二时期检测出微量,此后均未检出,可见ABA的含量呈下降趋势。

| Abstract: | Virus free plantlets in vitro of potato cvs.Favorita and Shepody were used for the experi-ment.The changes of endohormones GA 3 ,KT,IAA,and ABA during the dormancy and sprouting of microtu-bers in vitro were investigated.The results showed that the contents of GA 3 ,KT,and IAA in dormant microtubers were much lower than those in dormancy re leased ones;the content of ABA was detected only in the first stage,and therefo re it may be conclude that ABA decreased abruptly in dormancy released microtube rs. |
