| 英文摘要 | In the face of ongoing climatic changes, understanding the species' sap flow responses is of crucial importance for adaptation and resilience of ecosystems. This study investigated diurnal variability and radial sap flux density (Js) in a natural Juniperus drupacea forest on Mt Parnon and determined the climatic factors affecting its total sap flow (Qs). Between July 2021 and March 2022, Granier-type sensors and automatic weather stations monitored Js of J. drupacea trees and environmental factors. Utilizing a multi-point sensor for Js radial profile variability, correction factors were applied to calculate (Qs), ranging from 4.78 to 16.18 L day(-1). In drier months of the study period (July-September), Qs progressively increased with increasing PAR and soil temperature, reaching a plateau at maximum values (app. 600 mu mol m(-2) s(-1) and 26 degrees C respectively) indicating partial stomatal closure. Whereas, during the wetter period (October-March), when water was no longer a limiting factor, VPD and PAR emerged as significant controllers of stand transpiration. In this period, Qs responded positively to increasing soil water content (theta) only on days with high VPD (>0.5 kPa). The studied J. drupacea stand demonstrated adaptability to varying environmental conditions, crucial for the species' survival, considering anticipated climate change scenarios. |
