以欧亚旋覆花(Inula britannica L.)无菌苗为材料,研究了不同浓度调吡脲(CPPU)对其叶片、根愈伤组织诱导的影响。结果显示,CPPU的浓度为0.10 mg/L时,叶片的愈伤组织诱导率为82.9%,且诱导出的愈伤组织生长好。CPPU的浓度为0.50 mg/L时,...以欧亚旋覆花(Inula britannica L.)无菌苗为材料,研究了不同浓度调吡脲(CPPU)对其叶片、根愈伤组织诱导的影响。结果显示,CPPU的浓度为0.10 mg/L时,叶片的愈伤组织诱导率为82.9%,且诱导出的愈伤组织生长好。CPPU的浓度为0.50 mg/L时,根的愈伤组织诱导率最高,达100.0%,愈伤组织生长最好,呈浅黄绿色,部分带有红色斑点,质地疏松,具光泽。展开更多
