摘　　要：以麻风树无菌苗下胚轴、子叶和叶柄为外植体,在含有不同浓度的BA和IAA MS培养基上进行麻风树再生芽的研究.结果表明,最佳外植体为下胚轴;最佳不定芽诱导培养基为MS+1.0 mg/L BA+2.0 mg/L IAA,不定芽诱导率达100%;最佳不定根诱导培养基为MS+1.0 mg/L IAA,生根率达100%.The cotyledons, petioles and hypocotyls of Jatropha curcas were used as explants and grown on MS media containing different concentrations of BA and IAA. The results showed that the hypocotyl explants on MS ＋1 mg/L BA＋2.0 mg/L IAA sucrose was the best for bud regeneration, the adventitious bud differentiation frequency being 100%. MS ＋1.0 mg/L was the best for the formation and growth of adventitious roots, with a rooting freqnency of 100%.
