Effects of high field temperature on summer maize grain yield and quality

Abstract

Abstract: A field study with two summer maize cultivars ND108 and YD13 showed that increased field temperature (3 ℃) at the stage from male tetrad to maturity had significant effects on their grain yield and quality. The grain yield of ND108 and YD13 decreased by 46.6% and 45.1%, grain crude protein content increased by 11.6% and 2.02%, ether extract content decreased by 38.9% and 9.6%, starch (mainly amylopection) content decreased by 7.0% and 8.4%, and lysine content decreased by 58.9% and 51.2%, respectively.

Key words: Black earth, CH₄ emission, Microbial biomass, Soil respiration
