Abstract:

In this paper, the effects of high temperature stress on maize production were analyzed from six aspects including yield and dry matter accumulation, photosynthesis, pollen, pollination and fertilization, seed grout, seed quality and endogenous hormones. The results showed that high temperature affected pollination and seed production, dry matter accumulation and endogenous hormone content of maize, decreased the photosynthetic rate and seed filling rate, thus decreased the seed yield. In addition, high temperature increased the protein content in the seeds, so that the starch and fat content decreased, affecting the quality of the seeds. Through breeding and selection of resistant varieties to high temperature, with the use of exogenous hormones and micro fertilizer, and the adoption of appropriate late sowing and appropriate water and fertilizer cultivation measures, corn efficient production with high temperature resistance could be achieved.
