A soil bacterivorous nematode feeding on bacteria B1 and B2 was isolated from rhizosphere soil of wheat and cultured on potato sucrose agar medium(PSA).
从小麦根际土中分离得到一种能取食B1和B2两种细菌的土壤食细菌线虫，并在马铃薯蔗糖培养基上富化培养成功。
B5 as basic medium appended with different concentrations of sucrose, AGAR and different hormone combinations was used to optimize the culture technique for DH line in Brassica napus l.
以B5培养基为基础培养基，添加不同浓度的蔗糖、琼脂及不同激素组合进行试验，对油菜DH系的组培技术进行优化。
The experimental results showed that the actions of all the five factors to the bio wave growth were extremely remarkable, and the order was agar, peptone, sucrose, beef extract, yeast extract.
方差分析结果显示，各因子对菌落直径的影响都极显著，它们的作用大小依次为：琼脂，蛋白胨，蔗糖，牛肉浸膏，酵母浸出汁；
