Effects of Different Hormone Treatments on Cutting Effect of Actinidia arguta Siet.et Zucc.
In order to explore the scientific and efficient cutting seedling technology of A.arguta,the effects of IAA,IBA and NAA growth hormones and their concentrations on its cutting rooting were studied in this paper.The re-sults showed that the three hormones significantly promoted the rooting rate,root growth and new branch growth,and the synergistic effect of IAA hormone was the best.Among the treatments with different concentrations,the roo-ting rate of IAA(200 mg/L)was 86.67％,the number of lateral roots was 13.8,the root quality was the best,the root length and root diameter were 18.60 cm and 1.83 mm,the growth of new branches was the best,the length of new branches was 5.82 cm,and the number of bud holes was 11.0.There were significant differences in rooting rate,number of lateral roots,root length,root diameter,new branch length and number of bud holes among different hor-mone and concentration treatments.To sum up,IAA(200 mg/L)was the most suitable hormone treatment and the rooting effect was the best.
