【摘要】 用扫描电镜对黑荆树花药及花粉微观形态进行观察,其形态结构与以往报道的花药形态结构有差异。绒毡层以外是由结构块交错排列而成;花药纵裂的两侧及两花药片之间的结构块比较规则。每一个花药产生8个花粉复合体,每个复合体由16个花粉粒组成,复合体花粉的纹饰与绒毡层的形态结构吻合。更多还原

【Abstract】 An observational experiment has been made on the micro-morphology of the anther and pollen of black wattle (Acacia meansii) with the scanning electron microscope.The result indicates that the morphological structure of the anther turns out to be somewhat different from the previous reports. The structure of anther wall, with the exception of tapetum, consists of a series of structural constituents. Each individual anther produces 8 polliniums, while one pollinium is composed of IQ pollen particles. In addition, the pollinium pattern is in correspondence with the morphological structure of the tapetum.更多还原
