The Effect of Regulator Application on Heartwood Formation in Dalbergia odorifera Trees
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 con-centrations 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.
