摘　　要：以灰楸茎段为试验材料,进行了灰楸的植株再生研究。结果表明:灰楸茎段愈伤组织和芽诱导最适培养基为MS+0.3 mg/LIBA+5 mg/LBA,丛生芽诱导最适培养基为MS+0.1 mg/LNAA+12 mg/LBA,根诱导最适培养基为1/2MS+0.5mg/L NAA。Taking the stem segment as the explant,the in vitro plant regeneration of Catalpa bungei was studied.The results showed that the optimum medium for the inducement of callus and buds from the stem segment of Catalpa bungei was MS+0.3 mg/L IBA+5 mg/L BA,the optimum medium for the inducement of tufty adventitious buds was MS+0.1 mg/L NAA+12 mg/L BA,and the optimum medium for the root inducement was 1/2MS+0.5 mg/L NAA.
