Hydraulic differences between flowers and leaves are driven primarily by pressure-volume traits and water loss

open access: yesFrontiers in Plant Science, 2023
Flowers are critical for successful reproduction and have been a major axis of diversification among angiosperms. As the frequency and severity of droughts are increasing globally, maintaining water balance of flowers is crucial for food security and ...
