摘　　要：对红冠桉10个无性系组培快繁的关键因子即增殖和生根的激素配比进行研究,结果表明:在相同条件下不同无性系的增殖倍数和生根率差异明显,增殖倍数最高的H14-1为5.5倍,最低的H11-1为2.2倍;生根率最高的H06-2为91.1%,最低的H11-1为40.4%。同一无性系H08-1在不同的激素配比中,继代增殖的最佳组合为6-BA 1.0mg·L-1+NAA 0.1mg·L-1,最差组合是6-BA 1.5mg·L-1+NAA 0.2mg·L-1,生根的最佳组合为IBA 1.5mg·L-1+NAA 0.2mg·L-1,最差组合为IBA 1.0mg·L-1+NAA 0.1mg·L-1。The key factors of hormone combination in propagation and rooting of C orymbia ptychocarpa tissue culture were studied.There were remarkable differenc es in the speed of propagation and rate of rooting between 10 clones of Corymbia ptychocarpa on the same hormone combination.The highest propagation speed was up to 5.5 times of clone H14-1,and the slowest clone H14-1 is only 2.2 times . For clone H08-1,the propagation speed was the highest in 6-BA 1.0 mg·L-1 ＋ NAA 0.1 mg·L-1 medium, and the lowest in 6-BA 1.5 mg·L-1 ＋ NAA 0.2 mg ·L-1. The effect of rooting from rebuilt stem was in IBA 1.5 mg·L-1＋ NAA 0. 2 mg·L-1 and the worst was in IBA1.0 mg·L-1＋ NAA 0.1 mg·L-1.
