Table 1. Chlorophyll-a fluorescence induction parameters in plants grown from seeds soaked in distilled water (DW) or NaSA seed-soaked (SS) or sprayed with 0.5 mM NaSA, and before (20°C) and after 4 h heat treatment at 35°C.

Mean values ± SD; n = 5. The different letters indicate statistically significant differences at the p<0.05 level.
