在制作食用菌母种的PDA培养基过程中,对马铃薯一般都要去皮,不去皮行不行?去皮与不去皮有什么区别?去皮的程度又是如何?为了探讨这些问题,做了以下试验,现简报如下: (一)供试材料 菌株为洛平1号,广温型,由我校培育而成。马铃薯(要求色泽淡黄无青皮,果形好,未发芽),琼脂,葡萄糖。 (二)试验方法 将马铃薯清洗后,挖去芽眼后按以下三种处理:A.不去皮,直接切成小块,按一定配比熬制成PDA培养基。D.用刀轻轻刮去外层皮,按一定配比熬制成PDA培养基。C.用刀削去外层皮,以稍带薯肉为宜,按一定配比熬制成PDA培养基。各处理 In the process of making edible fungi mother PDA medium, the potato generally have to peel, not peeled okay? What is the difference between peeled and non-peeled? The extent of peeled? In order to explore these issues, The following tests were made, are briefings are as follows: (A) The test material strain Luoping 1, wide temperature type, nurtured by our school. Potato (yellowish green color is not required), agar, glucose. (B) Test Method After cleaning the potato, dig the eye after the shoot according to the following three treatments: A. Non-peeled, cut directly into small pieces, according to a certain ratio boiled into a PDA medium. D. gently scrape the outer skin with a knife, according to a certain ratio boiled made of PDA medium. C. cut with a knife to the outer skin, with a little sweet potato is appropriate, according to a certain ratio brewed into a PDA medium. Each treatment
