英文摘要The effects of nano-ZnO on the inhibition efficiency of the activity of wheat Fusarium head blight pathogen, wheat seed germination, and seedling growth were investigated, and the feasibility of using it as a novel seed treatment agent was determined. Results showed that (1) the survival rate of pathogenic conidia was significantly reduced when the nano-ZnO concentration was 50 mg L-1. The survival rate was dropped to the lowest when the nano-ZnO concentration was 100 mg L-1, and the growth of the mycelium of Fusarium head blight pathogen was significantly inhibited when 100 mg L-1 was applied. (2) Nano-ZnO treatment increased germination rate, seedling length, root length, and dry matter weight to different degrees. When treated with nano-ZnO at a concentration of 50 mg L-1, nano-ZnO significantly improved infested wheat seedlings, while the superoxide dismutase (SOD) and catalase (CAT) in vivo activities and malondialdehyde (MDA) content were decreased. (3) Nano-ZnO had no adverse effects on the seed germination and seedling growth of healthy wheat. It also increased SOD and CAT activities in early seedlings and decreased MDA content. Therefore, nano-ZnO not only inhibits pathogen activity and increases seed germination rate but also has a certain role in promoting the growth of healthy seeds. These results show an important application prospect for nano-ZnO that can be applied to crop seed treatment to prevent seed diseases.
