Aseptic germination and rhizome differentiation ofCymbidium kanranMakino
Taking mature seeds of Cymbidium kanranMakino as material, the biological characteristics, vitality, asepticgermination characteristics and the differentiation of rhizomes were discussed. The result showed that the seed vitality ofC. kanran is relatively high with the value of 78.22%; the optimum medium for germination is 1/4 MS+NAA 0.2 mg/L+6-BA 3 mg/L (pH 5.8), with the germination rate of 86.87%; the optimum medium for rhizome differentiation is 1/2 MS+NAA 0.2 mg/L+6-BA 2 mg/L (Ph 5.8), with the differentiation rate of 93.33%.
