摘　　要：通过细绿萍（Ａｚｏｌｌａ ｆｉｌｉｃｕｌｏｉｄｅｓ）×小叶萍（Ａ．ｍ ｉｃｒｏｐｈｙｌｌａ）、细绿萍×墨西哥萍（Ａ．ｍ ｅｘｉｃａｎａ）种间，以及细绿萍×印度萍（Ａ．ｉｍ ｂｒｉｃａｔａ）亚属间正反交杂种Ｆ１ 代叶色变化，揭示杂种一代白化性状是母本细绿萍细胞质遗传的变异。电镜观察发现，白化苗质体结构异常，且淡绿苗组织细胞中含有正常叶绿体和异常质体。推测二者均可能和质体基因变异有关。不同杂交类型苗的白化程度和白化机率存在明显差异，且随着核基因变化呈现规律的变化。据此推测。By investigating the variance of Azolla leaf colour of F 1 generation obtained from negative and positive crossing of Azolla between two species (Azolla filiculoides×Azolla leaf colour of F 1 generation obtained from negative and positive crossing of Azolla between two species (Azolla filiculoides× leaf colour of F 1 generation obtained from negative and positive crossing of Azolla between two species (Azolla filiculoides×Azolla between two species (Azolla filiculoides× between two species (Azolla filiculoides×Azolla filiculoides××A.microphylla,A.filiculoides×A.mexicana)and two subgenus (A.filiculoides×A.imbricata),it was revealed that the albinism of the hybrid F 1 generation was variation resulting from maternal cytoplasmic inheritance,when A.filiculoide was used as female parent.Electron microscopic observation demonstrated abnormal development of plastid in the albino sporeling.The cell of light green seedling contained both normal and abnormal plastid.Both were probably related to variation in the plastid genotype.Significant difference occurred in the degree and freguency of albinism from various crossing forms ,and such change had its vegularity in accord with the variation of the nuclear genotype.The results speculated that albinism were also closely related to the nuclear genotype.
