Elevated Respiration-to-Photosynthesis Ratio Under High Nighttime Temperature Constrains Mungbean Yield and Identifies Genotypic Targets for Climate Adaptation in Subtropical Farming Systems
Mungbean is a nitrogen-fixing break crop in subtropical broadacre cereal rotation, yet how high nighttime temperatures (HNTs) threaten its agronomic contributions remain poorly characterized. A controlled environment (CE) experiment (low nighttime temperature, LNT: 20 °C vs. high nighttime temperature, HNT: 25 °C) and...
