水稻不同品种对白叶枯病的抗病性不同。用人工接种的方法测定1209个品种,未发现有完全不发生白叶枯病的品种,但是发病较轻可列为抗病的,约占23%左右。高度抗病的品种26个,占2.15%。(禾山)稻和粳稻品种都有发病很重的,但是,粳稻抗病品种比(禾山)稻多。晚稻此早稻和中稻多。抗病品种叶片的有机物成分和含量与感病品种不同,抗病品种的多元酚和糖的含量高于感病的品种,游离氨基酸中的谷氨酸和门参氨酸的含量低于感病的品种。
The resistance of different rice varieties to bacterial blight is different. The method of artificial inoculation was used to determine 1209 cultivars. No cultivars were found which did not occur bacterial blight at all. However, the less severe ones were resistant to disease, accounting for about 23%. 26 highly resistant varieties accounted for 2.15%. (Heshan) rice and japonica varieties have a heavy incidence, however, japonica resistant varieties more than (Heshan) rice. Late rice This early rice and more rice. The content and composition of organic matter in leaves of resistant varieties were different from those of susceptible varieties. The contents of polyphenols and sugars in resistant varieties were higher than those in susceptible varieties, and the content of glutamic acid and ghreonine in free amino acids was lower than those in susceptible varieties Variety.
