摘要:

以‘冠军’芦笋为试材,研究雌花、雄花发育过程中内源激素和多胺含量的变化,结果表
明,在芦笋雌花发育过程中,GA3 含量始终高于雄花,ABA、ZR 和IAA 含量从两性发育期到单性发育期
呈降低趋势;而雄花中的ABA、ZR 和IAA 含量则从两性发育期到单性发育期迅速上升。雌花GA3/ABA、
GA3/IAA、GA3/ZR 比值在两性发育期较雄花低,到单性发育期迅速升高,表明较高水平的GA3 和低水平
的ABA、IAA、ZR 与雌性器官选择性发育有关,而较高水平的ABA、ZR 和IAA 与雄性器官选择性发育
有关。雌花发育过程中多胺Spd、Put 和Spm 含量均呈先迅速升高后又下降的趋势,而雄花中3 种多胺的
含量相对稳定,高水平的Spm、Spd 和Put 与雌性器官发育有关。

Abstract:

Content change was studied on endogenous hormones and polyamine during development
of male and female flowers of Asparagus officinalis L.‘Champion’. The results showed that GA3 content
in female flowers was constantly higher than that in male. ABA,ZR and IAA contents decreased in female
flowers from hermaphroditic stage to unisexual stage,while ABA,ZR and IAA contents in male flowers
increased rapidly from hermaphroditic stage to unisexual stage. Ratios of GA3/ABA,GA3/IAA and
GA3/ZR at hermaphroditic stage were lower in female flowers than that in male flowers,however they
increased rapidly at unisexual stage. These results indicated that higher level of GA3 and lower level of
ABA,IAA and ZR were related to the development of female organ and higher level of ABA,ZR and IAA
were related to the development of male organ in asparagus. Spd,Put and Spm contents increased rapidly
and then decreased during development of female flowers,but they remained stable in male flowers.
Higher level of Spm,Spd and Put might be related to the development of female organ.

Key words: Asparagus officinalis, sex differentiation, endogenous hormones, polyamine
