小麦初生叶接种条锈菌后，亲和反应寄主叶片ＲＮａｓｅ活性，分别在潜育期和产孢期呈双峰型增长；不亲和反应叶片ＲＮａｓｅ活性在侵染初期高于健康对照，但低于亲和性反应，其后随着病程发展，近免疫反应叶片ＲＮａｓｅ活性与对照相同，而中度抗病反应叶片也呈双峰增长，峰高及峰延续时间不同于亲和性反应。条锈菌侵染对ＤＮａｓｅ活性影响较小，亲和反应叶片仅在产孢阶段ＤＮａｓｅ活性有所增强，中度抗病反应叶片在显症时活性增强。
After inoculation of P. rust, the RNase activity of the host plants in the affinity reaction showed a bimodal increase in the stages of incubation and sporulation respectively. The RNase activity of the non-reactive leaves was higher than that of the healthy controls in the early stage of infection, In the affinity reaction, the RNase activity of near-immune-reaction leaves was the same as that of the control, and then the moderate-disease-resistant leaves showed bimodal growth with peak duration and peak duration different from the affinity reaction. Stripe rust infection had little effect on the activity of DNase, but the activity of DNase in the affinity reaction leaves only increased during the sporulation stage.
