Wheat plants were studied in Mediterranean conditions to understand how they use sunlight and water to grow. The researchers found that wheat's photosynthesis and water use efficiency stayed consistent across different sites. The amount of sunlight and water available affected how well the plants could grow. The best time for photosynthesis was in the morning, with a dip in the middle of the day when it was very hot. By studying how wheat plants respond to their environment, scientists can better prepare for changes in climate and develop ways to keep crops healthy for food security.
