通过对华中五味子雄花发育特征的研究,旨在为遗传育种和栽培管理提供参考.采用SMZ—168体视显微镜对华中五味子不同发育时期雄花形态特征进行观察,采用石蜡切片法对其细胞结构特征进行研究,采用蒽酮乙酸乙酯比色法测量其花部可溶性糖的含量,采用考马斯亮蓝法测量其花部可溶性蛋白的含量.不同发育时期花柄细胞结构无明显差异,由内至外分别为维管柱、皮层和表皮;不同发育时期花瓣细胞结构无差异,随着花的发育,薄壁细胞不断分裂,花瓣增厚,花瓣上存在气孔;花药及花粉在Ⅴ(花冠展开期)发育成熟,外部形态表现为内侧花瓣全部变红,外侧花瓣绿色,花蕾顶部露出红色,花瓣逐渐展开.不同发育时期,雄花花柄、花...

In order to provide basis for its genetic breeding studies and cultivation management, growth and developmental characteristics of its male flower were studied. At different development stages of S.sphenanthera male flowers, the morphological characteristics were observed by using SMZ-168 stereomicroscope, the cell structure characteristics were studied by paraffin method, the solubility sugar of S.sphenanthera male flowers were measured by anthrone- ethyl acetate acid colorimetry, the soluble protein were measured by coomassie Brilliant blue G...
