我们试用稻叶离体接种法鉴定品种的抗瘟能力。此法可以随时随地采集各种不同品种的叶片测定其抗性,可重复多次进行,并可用来筛选防治稻瘟病的新农药和鉴别病菌的生理小种。 We tried rice in vitro inoculation method to identify varieties of blast-resistant ability. This method can collect leaves of all varieties at any time to measure its resistance, which can be repeated for many times. It can also be used to screen new pesticides for preventing and controlling rice blast and identify the germs of bacteria.
