【摘要】 以1/2MS为基本培养基,加入华石斛内生菌根真菌的菌丝提取物,对华石斛无根小苗进行诱导培养。结果表明:R5～R9号真菌诱导子均可不同程度地促进华石斛的生长,在5种真菌诱导子中,R6的诱导效果最好;R3和R4对华石斛生长和分化无明显的促进效果。7种不同菌株对华石斛组培苗的促进作用依次为:R6>R8>R9>R7>R5>R3>R4。更多还原

【Abstract】 The effects of fungal elicitors from Dendrobium sinense on its shoot growth in vitro were investigated. Plantlets were induced on the basal medium of 1/2 MS with the extraction of entophytic mycorrhizal fungi of Dendrobium sinense. The result shows that fungal elicitors of R5~R9 considerably promoted the growth of the plantlets. R6 did the best. Both R3 and R4 had no significant effect on enhancing the growth and differentiation of D. sinense. The effects of 7 fungal elicitors on the growth of the plantlets were in the order of R6>R8>R9>R7>R5>R3>R4.更多还原
