外源钙离子对香菇菌丝生长的影响

- Effect of Exogenous Calcium on Lentinula edodes Mycelium Growth

- 摘要:
- 以香菇66# 、236#和808#菌株为试材，采用统计分析及荧光显微镜观察等方法，将富钙和无钙培养基与对照培养基对比，分析了钙离子对香菇菌丝生长速度、菌丝尖端分支和菌丝生物量的影响。结果表明：与对照相比，香菇菌丝在富钙和无钙平板培养基中满板时间分别减少或增加1 d。显微观察发现富钙培养基生长的菌丝尖端长势旺盛，分枝减少；无钙培养基生长的菌丝尖端长势较弱，分枝增多。生物量统计表明，钙离子对香菇菌丝生物积累具有促进作用,且在不同香菇品种中钙离子对香菇菌丝生长的影响趋势相同。
- Abstract:
- Statistical analysis and fluorescence microscopy were used to analysis the effect of calcium on the mycelium growth rate，mycelium tip growth and mycelium weight of L.edodes 66#、236# and 808# which were cultured in calcium-enriched，calcium-free and control culture medium.The results showed that compared with the control，the time of the full plate in the calcium-enriched and calcium-free plate culture medium was decreased or increased by one day.Microscopic observation showed that the medium tip of cultured on calcium rich medium was growing vigorously，fewer branches.Medium tip of cultured on calcium free medium was growing weaker，more branches.The biomass statistics showed that the calcium could promote the accumulation of the mycelium.Moreover，the effect of calcium on the medium growth was the same in different L.edodes strains.
