Abstract: The stem of Armeniaca vulgaris ‘Badou’ was used as explants and MS as basic substrate to induce plant regeneration and select salt-tolerant plant. The results showed that the stem of ‘Badou’ in April and May sterilized by 0.1% mercury for 8min was suitable, the stem in MS culture medium with 1.0mg/L 6-BA and 0.1 mg/L IBA proliferated quickly and grew rushingly, the perfect rooting medium was MS+0.1 mg/L NAA + 0.2 mg/L IBA, with its rooting rate of 46.3%, and the optimum salt concentration in selection of salt-tolerant tissue culture seedlings was 0.4~0.8, there were also significant difference between plants selected and their contrast.

摘要： 以淮北黄里‘巴斗杏’茎段为外植体，MS为基本培养基，通过茎段诱导植株再生及进行耐盐筛选。结果表明：采用4、5月‘巴斗杏’茎段用0.1%升汞灭菌8 min较适宜；在含有1.0 mg/L 6-BA和0.1 mg/L IBA的MS培养基上茎段增殖较快，生长旺盛；较理想的生根培养基为MS + NAA 0.1 mg/L + IBA 0.2 mg/L，生根率达46.3%；‘巴斗杏’组培苗进行耐盐筛选的适宜盐浓度为0.4%～0.8%，筛选植株与对照相比差异显著。
