Increase of catalase activity after inoculation could be an useful assistant index for early selection of eucalypt materials resistant to Pseudomonas solanacearum. 苗期接种青枯病菌后,杂种桉过氧化氢酶活性上升的幅度可作为早期抗病选育的一个重要的辅助依据。
If there are relationship between the catalase activity or the changes of catalase activity and the resistance, it can be regarded as physiological index to identify disease resistance, and that can conquer the defeats of conventional disease identification. 如果烟草不同抗感品种在感染CMV前后体内CAT酶活或其变化与抗病性之间存在相关关系的话,应可能作为鉴定抗病性的指标,并克服以前鉴定中的缺点。
