不同木屑培养料栽培香菇菌丝生长盛期、原基形成期和子实体成熟期胞外Cx酶(羧甲基纤维素酶)和C_2酶(β-葡萄糖苷酶)的活性是逐渐增强的,以确保碳素营养的充分供应。不同木屑培养料的成分只影响酶活性的相对大小,而不影响酶活性的变化规律。纤维素酶活性对子实体形成不起决定作用。磷酸二酯酶活性先渐增,至菇蕾形成才急剧下降,抑制其活性是诱导香菇子实体和产量形成的关键因素。
The activity of extracellular Cx enzyme (carboxymethylcellulase) and C_2 enzyme (β-glucosidase) was gradually increased during the primordium formation and fruiting body maturation with different sawdust culture materials, Ensure adequate supply of carbon nutrients. Different components of sawdust culture only affect the relative size of enzyme activity, without affecting the variation of enzyme activity. Cellulase activity can not play a decisive role in the formation of fruiting bodies. Phosphodiesterase activity first increased gradually to Gulei Lei sharp decline in the formation, inhibition of its activity is the key factor inducing mushroom fruiting bodies and yield formation.
