Table 2 Average values of each environmental factor (net radiation (Rn), air temperature (Ta), vapor pressure deficit (VPD), soil water content (SWC) at 5 cm depth) and maximum photosynthetic capacity (GPPmax) under the optimum value of the given environmental factor (Rnopt, Taopt, and VPDopt), which are marked in bold for both pre- and post-thinning.
From: Thinning altered the optimum photosynthetic environment in a subtropical coniferous plantation
