摘　　要：为探究不同生长调节剂对降香黄檀心材形成的影响,以6年生降香黄檀为研究对象,采用不同浓度的赤霉素(GA)、6-苄氨基腺嘌呤(6-BA)和吲哚乙酸(IAA)进行处理,以期为降香黄檀人工林的培育提供参考。结果表明,浓度为2%、3%、4%的GA和浓度2%、4%的6-BA和0.6%的IAA对降香黄檀心材形成有积极作用,浓度3%的6-BA和浓度为0.4%、0.8%的IAA部分指标低于对照(CK)组,浓度为0.6%的IAA处理效果最好。To explore the effect of different growth regulators on the formation of heartwood,this study used 6-year-old Dalbergia odorifera trees as the research material and treated them with various concentrations of gibberellin(GA),6-benzylamino adenine(6-BA)and indoleacetic acid(IAA),to provide a reference for plantation cultivation.The results showed that 2%,3%,4%GA,2%,4%6-BA,and 0.6%IAA had positive effects on the formation of the heartwood.The concentrations of 3%6-BA and 0.4%and 0.8%IAA were lower for some indicators than those of the control treatment(CK),and the treatment effect of 0.6%indoleacetic acid was the greatest.
