176蘑菇菌株,具有产量高,出菇早,转潮快,耐高温,容易管理等优良特性。正常的176菌株是匍匐型种,在试管斜面上长成较粗的线状菌索,贴生在培养基表面。但是,该菌株不易保藏,试管种经4～8℃冰箱保藏后会出现退化现象,菌丝变细或成粉状,并有少量黄色团状的气生菌丝间生,长成形状不纯的菌落,而且长速极慢,需40天以上才能长满试管。为此,我们于1982年对该菌株进行了复壮实验,其方法如下: 将冰箱保藏的176菌种接到综合PDA试管斜面上,25℃培养5～10天,待菌种萌发并开始延伸时, 176 mushroom strains, with high yield, fruiting early, fast tide, high temperature, easy to manage and other excellent features. The normal 176 strain is a creeping species that grows into a coarser linear strain on the tube’s bevel and adheres to the surface of the medium. However, the strain was not easy to be preserved. After being stored in the refrigerator at 4 ~ 8 ℃, the test tube degenerated. The mycelium became thinner or powdery, and a small amount of yellow mycelial aerial mycelium was born. Of the colonies, but also very slow speed, take more than 40 days to fill the test tube. To this end, we carried out the rejuvenation test of the strain in 1982, the method is as follows: The 176 strains of the refrigerator are connected to the integrated PDA tube slant, and cultured for 5 to 10 days at 25 DEG C, until the germination of the strain begins to extend ,
