In this paper, an orthogonal experiment was conducted to investigate the effects of the hormone type, hormone concentration, and cutting type on the rooting characteristics and rooting rate of one-year-old cuttings of C. heterophylla × C. avellana in the garden soil. The result showed that the maximal rooting rate was 79.33% and the optimal treatment was that using the low portion of the suckers as cuttings treated with 200×10^-6 IBA for 6 h or using up-middle current year branches as cuttings treated with 200×10^-6 ABT₃ for 6 h. Roots were mainly induced from the bark and some roots also developed from the callus tissues in hardwood cuttings of C. heterophylla × C. avellana.
