Stomatal size in Populus trichocarpa is related to climate and exhibits plasticity across growing environments.

As climate change continues to alter environments around the world, plants exhibit phenotypic plasticity that allows them to acclimate to the changing environment around them.The environment impacts plant physiology in many ways and assessing key physiological traits (such aspects of stomata, leaf pores) in broadly distributed species allows for an in-depth investigation into the impacts of climate. Forty-seven unique genotypes of the species Populus trichocarpa were collected from across Canada and planted in multiple common gardens, including one site in Eau Claire, Wisconsin (UWEC), and a second in Fargo, North Dakota (NDSU). The purpose of this experiment was to evaluate the associations between stomatal pore length and precipitation and humidity, two climate characteristics that are rapidly changing. By comparing the UWEC and NDSU data, we conclude that mean annual precipitation and relative humidity of the climate of origin have a significant association with stomatal pore length, and that pore length also demonstrates plasticity between gardens. While these findings demonstrate that climate has a direct impact on stomatal morphology, the extent to which these patterns will persist in the future remains unknown. Future research is needed to investigate how stomatal morphology will adapt to the changing climate.
