【摘要】 本试验对6个品种及20个野生材料的葡萄花粉形态及外壁纹饰进行了观察,结果表明:葡萄花粉在NPC分类系统中属N3P4C3型,不同种间花粉形态有细微差异,而且这种差异较稳定,可用于不同种间的鉴定研究;雌株花粉明显地小于雄株花粉,雌株花粉外壁纹饰为网状, 而雄株花粉外壁为穴状,因此葡萄花粉外壁纹饰可用于性别鉴定;葡萄属的花粉外壁具有连续覆盖层,上有穴状雕纹(foveolate),穴多为不规则形状,穴的大小、深度及密度种间有差异,依据外壁纹饰的进化趋势推测华东葡萄、秋葡萄、圆叶葡萄等较为原始,而蘡薁葡萄、燕山葡萄、小叶葛藟; 巨峰、沙地葡萄等为较进化的种类。更多还原

【Abstract】 The morphology and extine sculpture of 6 cultivars and 20 species of pollen in Vitis were studied. The results indicated that the morphology of pollen is different in Vitis. It can be used to idendify the species. There were great differences in the pollen feature of male and female of dioecious. The extine sculpture of pollen was foveolate or reticulate. On the basis of extine sculpture we infered that V. pseudoreticulata W. T. Wang, V. romanetii Roman., V. rotundifolia Michx. were primitive species; V. adstricta Hance, V. amurensis Rupr. var. yanshanensis, V. flexuosa var. parvifolia Gagn., V. rupestris Scheele were the most evolutionary species of all materials tested.更多还原
