Effects of Fungal Elicitors on the Growth of the Tissue Culture of Cymbidium Goeringii

Four different fungus strains that were isolated from the roots of Cymbidium goeringii are made of dry mycelial elicitor.Tissue cultures of Cymbidium goeringii were induced on basal culture medium of 1/2 MS with the fungal elicitor.The result showed that different fungual elicitor promoted the growth and differentiation of adventitious bud of tissue culture in different degree,the inducing effects were in the order of CF11CF3CF1CF8CK.CF11 and CF3 did the best,and the fresh weight have increased by 74.38%and 73.93%compared to the control.In addition,the fresh weight of tissue culture increased with adding fungal elicitor of CF1,the inducing effects were in the order of 20 g/L10 g/L5 g/L0 g/L.The fresh weight had significant difference compared with those in control when the fungal elicitor added to 20g/L.
