由此说明离体筛选的水稻抗纹枯病突变体的抗病机制与一般抗性品种类似。
These results suggested that in vitro screened rice somatic mutants resistant to sheath blight had the similar resistant mechanism as general resistant varieties.
由于缺乏理想的抗源、有效的鉴定方法，致使水稻纹枯病抗性遗传研究相对滞后。
Genetic studies on rice resistance to sheath blight were slow in that ideal resistant resources and effective method to identify resistance to rice sheath blight were short.
经过比较这四种诱导因子的诱导抗病性效果，确定了BTH和壳寡糖具有较好的诱导抗病效果，可作为水稻抗纹枯病的诱导因子。
We compared the induction effects of them against the rice sheath blight. The result shows that BTH and COS have the stronge inducing effects against the pathogen.
