Effects of Different Rooting Reagents on Rooting of Miniature Potted Rose Cuttings
Miniature potted rose has great ornamental value.At present,the industrialized production of miniature potted rose seedlings is low and the quality is uneven in the domestic cultivation and production,which seriously affects the commercial value of subsequent rose flowers.It is of great significance to study the cutting propagation technology of miniature potted roses to improve the quality of seedlings.To study the effects of different rooting reagent treatment on the growth and development of cutting seedling from 4 miniature potted rose varieties,different levels of Zhongshugenbao 201,indole-3-butyric acid(IBA),1-naphthlcetic acid(NAA),2,4-dichlorophenoxyacetic acid(2,4-D)solution and combinations of reagents were set as treatments,and the water(CK1)and the company's usual reagent(CK2,the rooting powder provided by Ziyu Flower Industry Co.,Ltd.)were used as controls.The root traits of cutting seedlings from 4 varieties were analyzed using principal component analysis,and the optimal rooting reagents treatment for cuttings was selected.The results showed that CK2 treatment had the best effect on promoting the growth and development of cutting seedling roots,and IBA and Zhongshugenbao 201 were followed.It was worth mentioning that most of the combination treatments of Zhongshugenbao 201 and IBA solution had good effects on the growth and development of cutting roots of 4 varieties,which were better than CK2,especially the combination of the 0.67 mL·L-1 Zhongshugenbao 201 and 1 500 mg·L-1 IBA,the root growth of cuttings in all tested varieties was excellent under this combination treatment.
