Effects of DCPTA on theFv/Fm(a), ΦPSII (b), qP (c), and NPQ (d) of the leaves of non-stressed and salinity-stressed maize seedlings. The plants were grown in a hydroponic solution that contained 0, 20, 100, or 400 μM DCPTA with or without 150 mM NaCl. The data are the means ± SEs (n = 5). The different letters on the bars indicate significant differences according to Duncan’s test (P = 0.05)
