氮源对番茄灰霉病菌菌丝生长的影响

Effect of Different Nitrogen Source on the Mucelium Growth of Botrytis Cinerea

选用15种常见氮源,应用固体和液体培养方法,筛选适宜番茄灰霉病菌生长的氮源营养物质。结果表明:在固体培养中,病菌对氮源的利用以蛋白胨为最好,其次为酵母膏。在液体培养中,病菌对氮源的利用以酵母膏为最好,其次为(NH4)2SO4。

Used 15 nitrogen sources to select the fittest nitrogen source by solid culturate and liquid culturate. The results of the experiments showed ： Peptone was the best nitrogen source in solid culturate,the second was yeast extract. Yeast extract was the best nitrogen source in liquid eulturate,the second was （NH4）2SO4.
