Název v původním jazyce

Plasticity in hydraulic architecture of Scots pine across Eurasia

Popis výsledku v původním jazyce

Widespread tree species must show physiological and structural plasticity to deal with contrasting water balance conditions. To investigate these plasticity mechanisms, a meta-analysis of Pinus sylvestris L. sap flow and its response to environmental variables was conducted using datasets from across its whole geographical range. For each site, a Jarvis-type, multiplicative model was used to fit the relationship between sap flow and PAR, vapour pressure deficit (D) and soil moisture deficit (SMD); and alogarithmic function was used to characterize the response of stomatal conductance (Gs) to D. The fitted parameters of those models were regressed against climatic parameters to study the plasticity of Scots pine with regard to dry/warm conditions. Theabsolute value of sap flow and its sensitivity to D and SMD increased with the average summer evaporative demand. However, relative sensitivity of Gs to D (m/Gs,ref) did not increase with evaporative demand across populations, and transpi
