Abstract

To clarify the relationships among water dynamics, soil water content and vapor pressure deficit (VPD) in a Larix gmelinii stand, eastern boreal Siberia, seasonal fluctuation of the stand water use (SF) and environmental factors were measured. SF increased rapidly after the needle flushing and reached the maximum value (2.7 mm d-1) around the middle of June, when needle expansion ceased. Thereafter, it decreased sharply and was maintained at about 75% level of the peak value till the end of July. The tendency for SF to level off at high VPD could be observed. From the analysis of the effect of soil water content (SWC) on canopy stomatal conductance, a close linear relation could be found between stomatal conductance and SWC at VPD
