Abstract:
Taking aseptic rose stem segments as materials and MS as basal medium,effect of exogenous 6-BA,TDZ on rose stem proliferation,TDZ and NAA on plant height and internode,active carbon concentration on rooting were explored.The results showed that 6-BA 4.0 mg/L had a maximum bud proliferation,so MS+6-BA 4.0 mg/L+active carbon 0.6 g/L was the optical proliferation medium.When TDZ was 1.0 mg/L,NAA was 0.05 mg/L,seedling had the maxium height of 5.02 cm and internode 0.40 cm.The optimum rooting medium was 1/2 MS+active carbon 1.0 g/L with a 92.9 rooting rate.
