同时以松叶牡丹的叶片和愈伤组织为感染材料，也进行了遗传转化研究。 - 2 ~ 4s sonication and co - cultured 6 days can enhance the efficienty of transformation of portulaca grandiflora hook . the concentration of agrobacterium and time of infection can distinctly affect the frequency of resistant tissues
进行6d的共培养可明显的提高二者的转化效率，同时采用适当的伤口处理如超声波处理2 4s对二者的转化也有很大的影响。 - The main factors influencing agrobacterium - mediated genetic transformation of portulaca grandiflora hook , are as follows . the concentration of kanamycin of devision leaves and the calli were 100mg / l and 200mg / l , respectively . calli infection can gain more gus gene transient expression and resistant tissuses than devision leaves
对松叶牡丹进行遗传转化研究发现，采用叶片作为外植体时， kan的浓度100mg / l就可抑制愈伤的诱导，而用愈伤组织作为材料感染时浓度要达到200mg / l才可。
