食用菌的交配系统和育种技术相当复杂。只有了解它的繁殖方式和生活史,才能把握主要环节,采取有效措施。一、菌丝发育和核行为食用菌大部分属于担子菌纲,它们的特点是能形成担子,有双核期,有桶状横隔,有的还有锁状连合。菌丝由孢子萌发而来,呈分枝状细丝,由菌丝细胞组成,许多菌丝聚集为菌丝体,它能穿入基质吸取营养,并通过细胞分裂不断生长发育,最后形成子实体。菌丝在整个生命过程中,经历三个发育阶段:①初生菌丝体,也叫同核体。由孢子萌发形成,每个菌丝细胞有一个核,细胞有不同配合型。②次生菌丝
Mating systems and breeding techniques are complicated. Only by understanding its mode of reproduction and life history can we grasp the major aspects and take effective measures. First, the mycelium development and nuclear behavior Most of the edible fungi belong to Basidiomycetes, they are characterized by the burden can be formed, a binuclear phase, a barrel-shaped diaphragm, and some even lock-like joint. Mycelium germination from the spores, were branched filaments, composed of mycelial cells, many mycelium gathered as mycelium, it can penetrate the matrix to absorb nutrients and continue to grow through cell division and development, and finally the formation of fruiting bodies . Mycelium throughout the course of life, through three developmental stages: ① myeloid, also known as the nucleus. By the spore germination, each hyphae cells have a nuclear, cells have different types. ② secondary mycelium
