摘要
对人工诱变的两个同源四倍体玫瑰香葡萄单株———四玫Ⅰ和四玫Ⅱ进行细胞组织学和遗传稳定性研究 ,结果表明 :(1)经过连续 3代的扦插 ,其组织发生层倍性结构没有变 ,四玫Ⅰ仍然是 4 4 4型 ,四玫Ⅱ仍然是 2 4 4型 ;(2 )四玫Ⅰ和四玫Ⅱ的实生苗均为 4 4
Cytohistology and genetic stability on three cutting progenices and seedlings of Simei I and Simei Ⅱ which are artifical induced tetraploid grapes were studied.The results were as follows:Their histological structures didn’t changed after three successive cutting progenies.Simei I was still 4 4 4 type and Simei Ⅱ was still 2 4 4 type.Their seedling were both 4 4 4 type.
