平菇新菌株“棕顶81”是我们从引进的紫孢侧耳(Pleurotus Sapidus)变异菌株中选育得到的,现将初步研究结果总结于后,供参考。一、选育经过1981年秋在紫孢侧耳瓶栽菇体中发现该变异菌株,遂采用菇组织分离法进行了分离保存。1982年10月将保存的原种扩大转接为栽培种,并通过瓶栽出菇试验,证明了该菌株变异性状能稳定遗传。以后又多次与其亲株(原菌株紫孢侧耳)和当地一些推广菌株进行比较试验和试种示范,进一步观察和测定了该菌株的发菌出菇动态、菇体经济性状和鲜菇产量。
The new Pleurotus ostreatus “brown top 81” is from the introduction of Pleurotus Pleurotus Pleurotus (Pleurotus Sapidus) mutant strains of breeding, the preliminary results are summarized below, for reference. First, breeding After the fall of 1981, the fungus Arborophore ear mushrooms found in the mutant strain, then the use of mushroom tissue separation was isolated and preserved. In October 1982, the preserved original species were expanded and transformed into cultivated species. The mushroom cultivation experiment was conducted to prove that the variation characteristics of the strain can be stably inherited. After many times with its pro-strain (the former strain of Pistia stratiotes) and some of the local promotion of strains to compare the test and test demonstration, further observation and determination of the strains of bacteria activity, mushroom economic performance and fresh mushroom production.
