我国的食用菌有360多种,多数是野生的。如何在分离培养中确定是担子菌,这是获得纯种的关键。担子菌一般具有担孢子、双核菌丝体和锁状联合等三个典型特征。在担子菌亚门约半数的菌种中,作为双核化菌丝的最常见的特征是形成锁状联合。那么,锁状联合的形成过程、形态特征及其来龙去脉是怎样的呢?这就要从担子菌的营养体谈起了。 There are 360 ​​kinds of edible mushrooms in our country, most are wild. How to determine in isolation culture is basidiomycete, which is the key to access to purebred. Basidiomycetes generally have three typical characteristics of basidiospore, binuclear mycelium and lock-like combination. In about half of the basidiomycetes, the most common feature as binucleated mycelium is the formation of a lock-like association. So, the formation of the lock-like shape, morphological characteristics and its ins and outs are what? From the nourishment of basidiomycetes talk about it.
