摘要
在试验的基础上 ,比较了甘蔗腋芽苗亚无性系 2代、3代与原种在大田性状上的差异。结果表明 :腋芽苗亚无性系在生长势、株高、出苗率、分蘖率、成茎率等性状上优于原种 ;亚无性系茎径和前期糖分低于原种 ,并在腋芽苗无性世代中逐渐得到恢复 ,在 3代左右完全达到原种水平。
The experimental results showed that the traits of subclones from axillary buds micropropagation were different from the donor. Of all of them, growth vigor, plant height, germination rate, tiller rate, millable stalk rate increased, while stalk diameter and sugar content in the early growing stage decreased. However, these differences diminished with the increasing of subclones' generation, and disappeared in the third generation.
