The purpose of this study was to identify the physiological mechanism underlying effects high temperature and waterlogging on summer maize. stem development yield maize hybrid Denghai 605 in response high-temperature stress, their combination applied for six days at third-leaf, sixth-leaf, tasseling stages were recorded. combined stresses reduced lignin biosynthetic enzyme activity accumulation, leading abnormal development. Reduction area number vascular bundles stems led dry matter accumulation allocation. Decreased grain weight all three relative a control. In summary, temperature, waterlogging, stress impaired more damaging than either alone.
