A Study on the Effects of Growth Regulators on Cutting Techniques of Cyclocarya paliurus

The effects of four growth regulators,namely,GGR6,SJCL,IAA and NAA on rooting of Cyclocarya paliurus cuttings were investigated.The results showed that dipping the cuttings in SJCL growth regulators 500 mg/L for 0.5 h showed the best result for rooting and the rooting rate was up to 64.57%.Different growth regulators had extremely significant effects on rooting number,rooting length of cuttings,SJCL had better effect than IAA and NAA on rooting numbers,GGR6 had better than IAA and NAA on rooting length.
