食用菌种一般分为母种、原种、栽培种。 母种是经孢子分离,组织分离,或寄居分离获得的菌种。目前通常用马铃薯——葡萄糖——琼脂作培养基。一般的食用菌在这种培养基上都能生长,也易于保存。保存的基本条件是:低温、干燥、无氧。母种保存有低温、液体石蜡、砂土等多种疗法。一般是将快要长满菌丝的试管放入4℃的冰箱内,此法可保存母种2—3个月,多则3—5个月。但草菇母种要在15(以上的温度中保存。在无冰箱时,可将斜面试管棉塞换上无菌的橡皮塞,
Edible mushrooms are generally divided into mother species, original species, cultivated species. The mother species is spore separation, tissue separation, or colonization obtained isolated strains. Currently, potato-glucose-agar is commonly used as a medium. Common mushrooms grow on this medium and are easy to preserve. The preservation of the basic conditions are: low temperature, dry, anaerobic. Mother species stored in a variety of low temperature, liquid paraffin, sand and other treatments. Generally, the test tube covered with mycelium will be placed in a refrigerator at 4 ° C. This method can save the mother species for 2-3 months, as many as 3-5 months. However, mushroom mother species to be stored at 15 (more than the temperature in the refrigerator, the bevel test tube can be replaced with a sterile rubber stopper,
