Contrasting stomatal sensitivity to temperature and soil drought in mature alpine conifers

Popis výsledku v původním jazyce

Conifers growing at high elevations need to optimize their stomatal conductance, gs, for maximizing photosynthetic yield while minimizing water loss under less favourable thermal conditions. Yet the ability of high elevation conifers to adjust their gs sensitivity to environmental drivers remains largely unexplored. We used 4 years of sap flow measurements to elucidate intraspecific and interspecific variability of gs in Larix decidua Mill. and Picea abies L. Karst along an elevational gradient and contrasting soil moisture conditions. Site and species specific gs response to main environmental drivers were examined, including vapour pressure deficit, air temperature, solar irradiance, and soil water potential. Our results indicate that maximum gs of L. decidua is moe than 2 times higher, shows a more plastic response to temperature, and down regulates gs stronger during atmospheric drought compared to P. abies. These differences allow L. decidua to exert more efficient water use, adjust to site spec
