中文摘要: |
应用人工接菌方法,小麦叶锈菌能在含有6-苄基氨基嘌呤洋菜培养基中的感病离体小麦叶段上产生夏孢子堆。它在药剂生物活性测定中反应较为灵敏,与室内活体生物测定有较高的相关性,但也存在一定差异。如果两者结合使用,则可取长补短,避免漏筛。 |
英文摘要: |
Wheat leaf rust urediospores were successfully produced on the infected wheat leaf segments cultured in 6 BA agar medium. It was very sensitive for the bioassay of candidate chemicals. Although differences existed. the result was highly correlated with that tested in vivo. |
