Leaf gas exchange and evaporation are governed by the water vapor pressure gradient and resistances, including stomatal and boundary layers. Wind speed plays a critical role in modifying these processes, yet the effects of natural wind variability on photosynthesis and stomatal behavior remain understudied. We used a variable boundary layer method to simulate natural wind variability and compared its effects with constant high wind conditions, commonly employed in gas exchange research. Our results showed that angiosperms were highly sensitive to changes in wind. Grapevines benefitted from increased wind, with photosynthesis improving by 14% and stomatal conductance increasing by 20% under high wind. Wheat displayed extreme sensitivity, with stomatal conductance increasing by 15% as wind intensified and decreasing similarly as it weakened, driven by mechanical interactions between guard and epidermal cells. In banana, stomatal conductance under constant high wind was 36% lower than under variable wind. In contrast, gymnosperms and ferns exhibited minimal responses, maintaining stable gas exchange due to structural adaptations like sunken stomata and limited guard-epidermal cell interactions. These findings emphasize the need to incorporate realistic wind dynamics in gas exchange studies. Ignoring wind variability can lead to inaccurate measurements, especially in sensitive angiosperms, and misinterpretation of their physiological performance.
