优良纯化的菌种,是食用菌栽培成功的根本保证。如何对常见食用菌试管母种外观进行鉴别,是每个制种工作者应该掌握的技术,现就这个问题作一简介:(一)双孢蘑菇菌丝在PDA 培养基上,菌丝纤细、稀疏,灰白色绒毛状或银白色绒毛状。根据菌丝着生方式可分三种类型:①气生型(绒毛型)菌株,孢子萌发7—9天出现星芒状菌落,菌丝健壮、细密、尖端粗直清晰,整齐一致,呈扇形伸展,气生菌丝似绒 Fine purified bacteria, is the fundamental guarantee for the success of edible cultivation. How to identify the appearance of common edible fungus tube mother is that each seed production workers should master the technology, is to make a brief introduction to this issue: (A) Agaricus bisporus mycelium in PDA medium, mycelium slender, Sparse, gray fluff or silvery white fluffy.
