摘　　要：对燕子掌叶片内源激素ZRs(玉米素核苷)、IAA(吲哚乙酸)、iPA(异戊烯基腺苷)、ABA(脱落酸)的含量变化进行研究,结果表明:具有相对低浓度的IAA、ABA,相对高浓度的iPA,ZRs和高浓度的CTK/ABA利于花的诱导,其中CTK/ABA起关键性作用;相对高浓度的IAA、ZRs、ABA和高浓度的CTK/IAA利于花茅的分化,其中CTK/IAA起关键性作用。The endogenous hormone ZRs, IAA, iPA and ABA contents were studied, the results showed that the lower IAA, AI3A contents and higher iPA, ZRs contents were required, meanwhile the high ratio of CTK to ABA probably dominated during floral induction; the higher IAA, ZRs and ABA contents were required during flower bud differentiation, meanwhile the ratio of CTK to IAA probably dominated.
