Temporal variation in measured values of precipitation (a), soil volumetric water content (0–1 m) (b), daily stand transpiration (c), and monthly stand transpiration (d) at the study site between June 2015 and November 2016 in the drought and ambient plots. Significant differences between drought and ambient plots within the same time are denoted by different lowercase letters. Values of monthly stand transpiration represent the mean ± SD for a sample size of n = 6. In June 2015, sap flow density was measured from June 10 to June 25, so the monthly stand transpiration in June was estimated proportionately. The total precipitation is 815 and 556 mm in 2015 and 2016, respectively. In the drought treatment, the throughfall is 326 and 222 mm in 2015 and 2016, respectively.
