Acceptor sides parameters M o and (1- V i )/(1- V j ) in leaves of grape plants sprayed with H 2 O ( filled circles ) and SA ( open circles ) at normal growth temperature (NT, 25°C), and treated with H 2 O ( filled triangles ) and SA ( open triangles ) under heat stress (HT, 43°C) and recovery. Each value is the mean ± SE of 4 replicates. Treatment conditions are described in Fig. 1. At the same time point, numerical values with different letters are significantly different (P < 0.05).
