在MS培养基中加入毒素的试验结果表明:毒素浓度和处理时间对芽块生长有较大的影响,毒素浓度为30%的处理和用100%浓度的毒素处理2天再转到正常MS培养基上的处理,均能保留一定比例受影响较少的芽块,因而MS培养基中加入毒素在西瓜抗枯萎病突变体离体筛选中是较适宜的处理方法。
The results of adding toxins in MS medium showed that the toxin concentration and the treatment time had a great influence on the growth of buds, and the treatment with 30% toxin and 100% toxin for 2 days and then to the normal MS culture All of the treatments could retain a certain proportion of buds that were less affected. Therefore, adding toxin in MS medium was an appropriate treatment method in vitro screening of watermelon Fusarium wilt mutants.
