High temperature effects on maize photosynthesis during stress and recovery phase at the seed setting stage.

ABSTRACT: With the climate change, high temperature (HT) stress will have more serious impacts on maize production. Photosynthesis is the basis of maize yield, which is also sensitive to HT. HT effects are not only occurred during the stress periods, but also lasted after the stress is removed, but with few attention. To explore the maize photosynthesis after HT removal, two maize varieties with different heat sensitivity (Jinhai 5 (JH) in 2021; JH and Xianyu 335 (XY) in 2022) were exposed to HT using the pot experiment in environment-controlled greenhouses. Photosynthesis and relevant physiological parameters were measured during stress periods and at the recovery phase. Results showed that at the ending of HT, maize photosynthesis were all significantly inhibited of the two maize varieties in the
