- 摘要:
- 以秋水仙素0、0.1、0.2、0.5、1.0、2.0 g/L 6个浓度梯度，分别处理大蒜根尖12、24、36、48和60 h，研究不同浓度的秋水仙素及不同处理时间对诱导大蒜根尖产生多倍体的效果。结果表明：在0.5 g/L处理浓度下，从24～48 h，大蒜根尖的膨大率均在82%以上，综合效果较好。
- Abstract:
- Colchicine under concentration of 0,0.1,0.2,0.5,1.0 and 2.0 g/L and garlic root tip were cultured 12,24,36,48 and 60 h separately，the effect of morphological changes of garlic root tip induced by different concentrations of colchicine at different periods were studied.The results showed that under 0.5 g/L treatment dealing with from 24 to 48 hours，the expansion rate was more than 82%，the comprehensive effect was better.
