| 摘 要： | 对刺梨系列品种小孢子发育时期的特点及其与花器外部形态的关系进行研究。结果表明,刺梨小孢子发育经四分体时期、单核期和双核期,各时期特征差异明显。刺梨小孢子发育时期与花蕾的外部形态特征、花药颜色密切相关,尤其与花蕾的大小关系密切。根据花器形态特征可以判断小孢子的发育时期,从而为刺梨花药离体培养接种外植体的选择提供科学依据。

| Abstract: | The correlation between microspore development stage and morphological characteristic of flower organ in Rose roxburghii was studied the results showed that there were tetrad phase,uni-nuclear phase and binuclear phase and there was significant difference in cytological characteristics of microspore development and microspore development period was closely related to morphological characteristics of buds and color of anthers,especially the size of buds. The research results could provide a scientific basis ... |
