Effects of Three Plant Growth Regulators on Cutting Propagation of Dalbergia tsoi
[Objective]The aim was to explore the effect of plant growth regulators on cutting propagation of Dalbergia tsoi.[Method]Taking D.tsoi as the research object,the cuttings of D.tsoi were soaked with different concentrations of IAA,IBA and NAA for different time,and the survival rate was counted after 45 days.[Result]Under different concentrations and soaking time treatments,three plant growth regulators had significant effects on the cutting propagation of D.tsoi.The best treatment for the three plant growth regulators was soaking for 30 min at a concentration of 500 mg/L IBA.[Conclusion]It could be applied in actual production.
