采用ＨＰＬＣ法分析比较了榨菜胞质雄性不育系和保持系花器发育过程中内源ＩＡＡ、ＺＴ和ＡＢＡ的变化．结果表明：不育系雄蕊内源ＩＡＡ和ＺＴ含量随花器发育而缓慢增长，在大花蕾和盛花时期，每枚雄蕊ＩＡＡ含量为１．８ｎｇ和８．０ｎｇ；ＺＴ含量为１９．２ｎｇ和２２．４ｎｇ，分别为同期保持系雄蕊的１７％、４１％和４０％、１５％，ＩＡＡ和ＺＴ出现明显亏损．从小花蕾→大花蕾→盛开花，不育系雄蕊中ＡＢＡ含量分别为同期保持系的４７％、１２％和１５％．随着花粉的发育和成熟，不育系雄蕊内ＡＢＡ亏损更明显．两系雌蕊中内源ＩＡＡ含量均极低，ＺＴ和ＡＢＡ含量差异也不及雄蕊明显
The changes of endogenous IAA, ZT and ABA in the cytoplasmic male sterile line and maintainer line of Tuber mustard were analyzed by HPLC. The results showed that the contents of IAA and ZT in the stamens increased slowly with the development of the floral organs. The IAA content of each stamen was 1.8 ng and 8.0 ng in the bud and flowering stage, respectively. The ZT content was 19.2 ng and 22, respectively. 4ng, which were 17%, 41% and 40%, 15% of the stamens of the same period, respectively. Significant losses were found in IAA and ZT. The ABA content of the stamens in the sterile lines was 47%, 12% and 15% of that of the maintainer lines in the buds from bud → bud → bud. With the development and maturation of pollen, ABA loss in the sterile stamens became more pronounced. The content of endogenous IAA in two lines of pistils was extremely low, and the difference of ZT and ABA contents was not as obvious as that of stamens
