Comparison on Propagation Technique of Different Softwood Cutting for Eucalyptus cloeziana
A single-factor experimental method was employed to investigate the effects of different rooting agents,cutting containers,and substrates on the rooting rate of softwood cuttings of Eucalyptus cloeziana,and to provide reference for cutting propagation technique of E.cloeziana.The results indicated that treatment with general-purpose rooting agents led to the formation of callus-like structures but resulted in a relatively low rooting rate.The use of anti-phenolic agents combined with indolebutyric acid(IAA)significantly reduced the formation of callus-like structures and promoted bark rooting.Cutting containers and substrates were found to have significant effects on the rooting rate of softwood cuttings.The combination of anti-phenolic agents,1 000 mg·L‒1 IAA,yellow clay loam,and non-woven fabric containers demonstrated the best rooting performance,which could achieve a high rooting rate of 72.1%.In August,the 30-day rooting rate of softwood cuttings reached 52.4%,accounting for 78.0%of the total rooting rate,However,prolonged rainy weather significantly reduced the rooting rate.
