PDA 是指由马铃薯,蔗糖和琼脂配制而成的培养基。常规配制法,马铃薯必须削皮。然而,作者发现用不削皮马铃薯制作的培养基对菌种萌发生长有利,为证实这个问题,作了如下试验。(一)培养基A.常规培养基:去皮马铃薯200克(取熬汁),蔗糖20克,琼脂18克,水1000毫升。B.试验培养基:去皮马铃薯100克,马铃薯皮100克(取熬汁)蔗糖20克,琼脂18克,水1000毫升。
PDA refers to a medium made of potato, sucrose and agar. Conventional preparation, the potato must be peeled. However, the authors found that using a medium made of peeled potato is advantageous for the germination and growth of the strain, and in order to confirm this problem, the following experiment was carried out. (A) medium A. conventional medium: peeled potato 200 grams (boil juice), 20 grams of sucrose, 18 grams of agar, 1000 ml of water. B. Test medium: peeled potato 100 grams, 100 grams of potato peel (boil juice) 20 grams of sucrose, 18 grams of agar, 1000 ml of water.
