Effect of plant growth regulators on the cutting propagation of Camellia azalea
The effect of cutting period and plant growth regulators on the cutting propagation of Camellia azalea was studied in this paper. The results showed that there was no significant difference between spring cuttings and summer cuttings of C.azalea, while the plant growth regulators caused significant difference among the survival rate, average root number and average root length as well as the steckling height of C. azalea' s cuttings (p <0.05 ). Among the thirteen plant growth regulators treatment, the optimal one was mixed plant growth regulators (80% IBA + 20% NAA) treatment with concentration of 0.5 g/L, which was better than that of NAA and IBA alone.
