Model analysis of the effects of atmospheric drivers of storage water use in Scots pine

Popis výsledku v původním jazyce

In this study we determined the microclimatic drivers of storage water use in Scots pine (Pinus sylvestris L.) growing in a temperate climate. The storage water use was modeled using the ANAFORE model, integrating a dynamic water flow and -- storage model with a process-based transpiration model. The model was calibrated and validated with sap flow measurements. Because soil water was never limiting during the study period, we were able to study atmospheric effects. Incoming radiation was the main driver of storage water use. The general trends of sap flow and storage water use are similar, and follow more or less the pattern of incoming radiation. Nevertheless, considerable differences in the day-to-day pattern of sap flow and storage water use were observed, mainly driven by VPD. During dry atmospheric conditions (high temperature and VPD) storage water use was reduced by closing stomata. This reduction was disproportionally higher than the reduction in measured sap flow.
