摘    要:月月竹(Menstruocalamus sichuanensis)作为优良的园林绿化竹种,近几年在南京林业大学竹种园中出现开花现象。以月月竹为研究对象,运用石蜡切片技术对其大、小孢子的发生和雌、雄配子体的发育过程进行了研究。结果表明:月月竹花药具4个药室,花药壁由表皮、药室内壁、中层、绒毡层4层结构组成,花药壁发育为单子叶型,绒毡层为腺质型,小孢子母细胞减数分裂中的胞质分裂为连续型,产生左右对称型小孢子。成熟花粉大多二细胞型,具1个萌发孔。月月竹子房为2心皮1室,侧膜胎座,1个倒生胚珠,双珠被,薄珠心。大孢子母细胞由一个雌性孢原细胞直接发育而成,大孢子四分体呈线型,合点端一个大孢子分化为功能大孢子,由功能大孢子发育为蓼型成熟胚囊。

关 键 词:月月竹  大孢子发生  小孢子发生  雄配子体  雌配子体

Abstract:As one of the good ornamental bamboo species,Menstruocalamus sichuanensis has been flowering in the bamboo garden of Nanjing Forestry University in recent years.The research on the megasporogenesis,microsporogenesis and the development of their female and male gametophyte in M.sichuanensis were made in this paper.The anther wall was consisted of four layers,they were epidermis,endothecium,middle layer and tapetum.The development of anther wall belonged to the monocotyledonous type.The tapetum was typical gl...
Keywords:Menstruocalamus sichuanensis  megasporogenesis  microsporogenesis  male gametophyte  female gametophyte
