| Abstract: | Effects experiment of cutting propagation of Rhododendron rivulare were studied with different root-inducing regulator and cutting time.The results showed that R.rivulare began to root 60 d later after cutting.The rooting rates were significant difference among different root-inducing regulator and cutting time.Taking indolebutyric acid as root-inducing regulator with concentration of 150 mg/L,the average rooting rate was 55% as cutting in October and 82% in July,and the highest rooting rate in July was 85%.Taking ABT as root-inducing regulator with concentration of 100 mg/L,the average rooting rate was 67% and the highest survival rate was 70%.Taking α-Naphthylacetic acid as root-inducing regulator with concentration of 100 mg/L,the average rooting rate was 58% and the highest rooting rate was 65%; |
