Effects of Various Growth Regulators on Raising Seedlings of Lonicera japonica Thund. by Hardwood Cuttings

Objective: To improve the survival rate of Lonicera japonica by hardwood cutting propagation. Methods:Four growth regulators were used to study the effect of raising seedlings of L.japonica by hardwood cuttings. Results: The different types of growth regulators treatment showed effect of raising seedling of L.japonica by hardwood cutting,and the concentration of the growth regulators had also influences,300 mg·L-1 IAA showed the best effect,the survival rate was increased by 96.16% compared with the CK. Conclusion: In the actual production,300 mg·L-1 IAA can be used to promote the growth of roots and branches,improve survival rate and to speed up the breeding of L.japonica by hardwood cuttings.
