In this study, gswas measured as the conductance to H2O fromthe Li-Cor 6400 system. For the future convenience, gswas con-verted to the conductance to CO2, by dividing by 1.57 according tothe differences of diffusion rates of CO2and H2O across stomata. Forcomparison of the two years, and to other studies, we referred themeasuring dates as days after the irrigation of reviving stage (Dari).Thereafter, the two measuring dates in 2013 were correspondingto Dari 22 and Dari 55, respectively, and the three measuring dateswere corresponding to Dari 31–32, Dari 48–50 and Dari 60–61,respectively.
