Abstract:: The annual hardwood of Corylus heterophylla×Corylus avellana was selected as cuttings，the effects of different concentrations of IBA and ABT 1 on cuttings individually or combinedly for 3 hours on rooting of cutting container were investigated.The results showed that ABT 1 with 100 mg?L-1 was the best in all the treatments，the rooting percentage was 77.22%，average primary lateral root number of cuttings was 10.33，average root length was 8.25 cm，the thickest root diameter was 1.91 mm，compared with the control significantly increased by 22.19 times，2.87 times，2.99 times，3.55 times;the suitable concentration of IBA was 400 mg?L-1，the rooting percentage was 25.00%;the suitable concentration of the combined treatment of IBA and ABT 1 was 100 mg?L-1 IBA+25 mg?L-1 ABT 1，the rooting percentage was 20.00%.In addition，the suitable treatment was steeping the cuttings for 3 hours with 100 mg?L-1 ABT 1 for Corylus heterophylla×Corylus avellana hardwood on rooting of cutting container.
