摘要/Abstract

摘要： 为了探究黄檗雌雄植株的形态学及生理学差异，对黄檗成树雌雄植株的形态学、叶片抗氧化防御酶活性及内源激素含量等指标开展对比研究，结果表明：黄檗雌雄植株形态存在显著差异，雌株叶宽比雄株大1.66±0.148 cm（P<0.05）、雌株枝间夹角比雄株大17.5±1.21°（P<0.001）；雌雄株叶片颜色存在差异，但叶绿素含量差异不显著；黄檗雌雄株超氧化物歧化酶（SOD）、过氧化物酶（POD）、过氧化氢酶活性（CAT）酶活性存在显著差异，CAT酶活性在7月最高，雌株含量大雄株；POD酶活性6月含量最高，雄株大于雌株；SOD酶活性8月最高，雄株大于雌株。内源激素赤霉素（GA3）含量雄株大于雌株；吲哚乙酸（IAA）含量为雌株大于雄株；玉米素（ZA）含量为雄株大于雌株，差异显著（P<0.05）；内源脱落酸（ABA）性别间无显著差异。黄檗雌雄植株在形态及生理学等指标上存在一定差异，说明黄檗雌雄植株为维持自身生长需要，在形态和生理方面都做出不同调整以适应生存环境。

Abstract: The morphology, antioxidant enzyme activity and endogenous hormone content index were contrasted to study the differences of morphology and physiology of male and female plants of Phellodendron amurense. The results show that there were significant difference inmorphology of male and female plant, leaves width in females was large 1.66±0.148 cm than males(P<0.05), branch angle were 17.5±1.21 biggerthan that male strains(P<0.001). There was difference in leaf color between male and female, but no significant difference in chlorophyll content. The activity of superoxide dismutase(SOD), peroxidase(POD) and catalase(CAT) were significantly different between the male and female plant. POD enzyme activity was the highest in June, the male was higher than the female. The activity of SOD activitywas the highest in August. The content of GA3 was higher in male than that in female. The content of indoleacetic acid(IAA) was higher in female than that in male. The content of zein(ZA) was higher in male than that in female(P<0.05). There was no significant difference in abscisic acid(ABA) between genders. There were some differences in morphological and physiological between male and female of P.amurense indicating that female and male plants made adjust ments in morphological and physiological to adapt to the living environment for maintain their own growth.
