微量元素对鸡油菌菌丝体生长的影响

Effect of Microelements on Mycelium Growth of Cantharelles cibarius

为探讨鸡油菌菌丝体生长的关键调控因素,研究了Zn、Mn、B对鸡油菌菌丝体培养生长的影响。结果表明,硫酸锰(MnSO4)对鸡油菌菌丝体生长具有明显的促进作用,当MnSO4浓度为0.05%时,鸡油菌菌丝体的干重、萌发率和活力指数分别比对照高16.2 mg、17%和0.96,呈极显著差异;ZnSO4比MnSO4更能促进鸡油菌菌丝体生长,0.07%浓度时,菌丝体干重、萌发率及活力指数等分别比对照高18.2 mg、22%和1.27,且表现出极显著差异。硼砂对鸡油菌菌丝体的生长影响不明显,在高浓度时还会抑制其生长。

The effect of Zn,Mn and B on mycelium growth of Cantharelles cibarius was studied to probe key factors regulating mycelium growth of Cantharelles cibarius.The results showed that MnSO4 and ZnSO4 could obviously promote mycelium growth of Cantharelles cibarius,the mycelium dry weight,germination rate and vigor index of 0.05% MnSO4 treatment was 16.2mg、17% and 0.96,significantly higher than CK respectively（P0.01）,the mycelium dry weight,germination rate and vigor index of 0.07% ZnSO4 treatment was 18.2mg、22% and 1.27,significantly higher than CK respectively（P0.01）,B had no obvious effect on mycelium growth of Cantharelles cibarius and high B concentration could inhibit mycelium growth of Cantharelles cibarius.
