摘　　要：观察研究表明 ,不育花药绒毡层细胞异常 ,造成花粉母细胞不能进行正常减数分裂 ,败育发生于四分体形成之前 ,无花粉粒形成。雄性不育花药组织内的不溶性多糖和蛋白质含量较可育花药低。The cytological and histochemical observation on the male sterile anther in watermelon G 17 AB line was made,it showed,the tapetum of the male sterile anther was abnormal,consequently,the meiosis of the microspore mother cells was abnormal,the abortion occurred before the tetrads formation,there was no any pollen formation in the anther chambers.The contents of polysaccharide and protein in the male sterile anther were lower.

关 键 词：西瓜 雄性不育 花药发育 不溶性多糖 蛋白质
