摘　　要：报道满江红三膘亚属(Euazolla)4个种——蕨状满江红(Azolla filiculoides)、小叶满江红(A.microphylla)、墨西哥满江红(A.mexicana)和卡洲满江红(A.Caroliniana)小孢子育性特点;卡洲满江红2个品种,其它3个种及种间杂种F1代小孢子育性特点。影响小孢子育性的两个主要因素是外界环境条件和遗传因素。讨论了小孢子育性研究对满江红物种划分的意义。The features of fertility in microspore of 4 species of Azolla in Euazolla were reported. The environmental condition and inhertance were the two factors affecting the fertility of microspore. The significance of study on the fertility in Azolla microspore to Azolla taxonomy was also discussed.
