SPAD, leaf color value; Ci, intercellular carbon dioxide concentration; A, net photosynthetic rate; gs, stomatal conductance; E, transpiration rate; VPD, atmospheric vapor pressure deficit;WUE, water use efficiency; F, F-test value; n, degrees of freedom. Superscript** indicates that the differences among treatments were significant at the level of 0.01; and superscript * indicates that the differences among treatments were significant at the level of 0.05.
