Abstract: 【OBJECTIVE】Taking the rootstocks of Cymbidium goeringii as test pieces, Cymbidium faberi ’ chun he ding’ and common Cymbidium faberi were employ as parents, study on Multiplication and differentiation of rhizomes in vitro of Cymbidium goeringii. 【METHOD】 Four factors of medium ,6-BA and NAA、IBA were design to study the effects on differentiation of rhizome. 【RESULTS】 The result show that the growth rate was affected evidently by media,The 1/2 MS was used as basal medium,The optimal Multiplication Conditions For therootstocks were that 1/2MS +BA0.1 +NAA0.1, The best differentiation medium was1/2 MS+BA1.0+IBA1.0,Firstly using 1/2MS + BA1.0 + IBA1.0 and then using B5 + BA1.0 +IBA1.0 could gain a higher differentiation rate of the rootstocks to 76 Percentage. 【CONCLUSION】Rapid Multiplication Techniques were Cultivation Cymbidium faberi variety import technological means .
