Abstract：Through an orthogonal experiment,the influence of two different hormone combinations of IBA and NAA on the cuttings of Carya illinoensis was studied.An orthogonal design experiment with five levels was carried out from different types of hormones,different concentrations,and different treatment times.The results showed that factors such as different concentrations,different types of hormones,and different hormone treatment times all had an impact on the rooting rate of the cuttings.The optimal combination was obtained.When the external environmental temperature was controlled at about 15 ℃ and the temperature of the cutting substrate was controlled at 25 ℃,the rooting rate was the highest after being treated with NAA at a concentration of 1 000 mg/L alone for 1 minute,which could reach 68.89％.For the cuttings that have successfully rooted,only the hormone concentration has a significant relationship with their average adventitious root length.
