摘要
用紫外光吸收法测定不同种根结线虫侵染的核酸含量,结果表明:在植物体内根结中核酸含量显著高于同株健部根及健株健根;病株除根结外,不同部位核酸含量均显著低于健株对应部位,全株也显著较健株含量低。这一趋势在根结内线虫核酸量低的情况下也存在。
Contents of nucleic acid in host plant infected by different root--knotnematodes were tested by means of UV absorption. The result shows thatthe content in root--knots is significantly higher than those in healthyroots of both the same plant and healthy plant. In addition to root--knots,the content in different parts of diseased plants is all significantly lowerthan the respective parts of healthy plant, and that of the total diseasedplant is lower than of healthy one, too. There exists the same trends inthe case of low content in Meloidogyne.
