摘要
利用镰刀菌酸（FA）为胁迫剂，以节瓜不定芽为筛选材料，进行节瓜抗枯萎病变异体离体筛选技术的研究，初步试验结果表明FA胁迫的适宜浓度为75～100mg／L。经过筛选的细胞系对FA的抗性较未经筛选的细胞系明显增强。初步建立了节瓜抗性变异体离体筛选体系，获得了抗FA变异体再生植株的自交种子。
Selection in vitro for the mutants with Fusarium acid （FA） resistance in chieh- qua was carried out. The result showed that the suitable concentration of FA for selection was 75～100 mg/L. The resistance to FA of the selected - colonies was higher than that of tile un-selected. The systcm of sclcetion in vitro for the resistant mutants in Chieh-qua was established. The inbreeding seeds of mutants were obtained.
