In order to explore the effects and mechanism of climate warming on the growth and yield of strong-gluten and high-quality wheat variety, Jimai 229 was used as the experimental material, and the effects of whole-growth warming on the growth and development, flag leaf senescence characteristics, and yield of Jimai 229 were investigated with the wheat grown at natural temperature in the field as control. The results showed that warming during the whole growth period increased the number of tillers, plant height, leaf area of the top leaf, SPAD value and above ground dry matter accumulation of Jimai 229 during the vegetative growth stage. However, it accelerated the decrease rate of leaf area and SPAD value of flag leaves after anthesis, and reduced dry matter translocation to spike. Warming had little effect on SOD, POD and CAT activities of flag leaves of Jimai 229 at the booting stage and anthesis stages, and MDA content and Pro content in flag leaves were at low level, which resulted in significant increase in the SOD activity of flag leaves, and reduced the POD and CAT activities to different degrees after anthesis, leading to the increase in MDA and Pro contents and the relative electrolytic leakage. Warming reduced the number of spikes and the thousand-grain weight of Jimai 229 by 20.3% and 10.0%, and the yield by 24.1%, with insignificant effect on the number of grains per spike. In conclusion, warming during the whole growth period can promote the vegetative growth of Jimai 229, which is not conductive to the photosynthesis and antioxidant action of wheat flag leaves during the reproductive growth stage, leading to accelerated senescence of the flag leaves and lower yield.
