摘　　要：利用X射线对东方百合组织培养形成的不定芽进行慢性照射,观察不同辐照剂量对不定芽生长的影响,并对不定芽过氧化物同工酶酶谱进行分析。结果表明:X射线对东方百合不定芽的生长有显著抑制作用,对不定芽增殖影响不明显,随着辐照剂量的增大,不定芽死亡率增大,X射线慢性辐照引起了POD同工酶酶带数目的改变,活性增强。X-ray chronic irradiation was added to the adventitious bud by the tissue culture of oriental lily. Effects of different doses of radiation on the adventitious bud were observed and POD isozyme patterns of the adventitious bud were analyzed. X-ray obviously inhibites the growth of the adventitious bud while shows little effect on its multiplication. With the increase of the dose of radiation, the death rate rises. X-ray chronic irradiation leads to the change of POD isozyme patterns＇ number and enhances the activity of these isozymes.
