摘　　要：用植物生长调节剂多效唑、乙烯利、矮壮素、B9对澳洲坚果幼树进行控梢处理,结果表明:多效唑对澳洲坚果幼树的生长有极显著的抑制作用,其中3和2.5g/L处理的幼树营养生长受到严重抑制;乙烯利对澳洲坚果幼树新梢的抽发、梢长、节间长有显著影响,1.5和2g/L处理后幼树的新梢表现出乙烯的"三重效应"。矮壮素和B9对澳洲坚果幼树新梢抽发抑制作用极显著,矮壮素1.5、2g/L处理的幼树在喷药后2个月没有抽发新梢;B9处理的幼树新梢抽发量很少,对照的新梢数是其它处理新梢数的数十倍。Plant growth regulators were applied to control branch of macadamia integrifolia. Results indicated that multi-effect Triazole could inhibite the growth of young tree significantly.Among the different concentrations, ifs obvious that the growth would be effected in 3g/L and 2.5g/L, It had remarkable effect on sprouting,shoot length and internode length of young macadamia tender shoot and showed the Triple Effect obviously while spraying ethephon in 1.5g/L and 2g/L.Besides, there was no sprouting for young tree after treated with Chormequat in 1.5g/ L and 2g/L in two month.B9 had the similar effect, but it had more tender shoots in control than that of in all other treated trees.
