Effects of Alethea components upon photosynthetic performance in salinity-stressed tomato plants. Values show net photosynthesis in salt-stressed tomato seedlings as a percentage of non-salt treated plants 8 d following salinity treatment (100 mM), with a pre-treatment of Alethea components 24 h prior to salt application. Potassium dihydrojasmonate (‘J’), sodium benzoate (‘S’), and the α-amino acid L-arginine (‘A’) were applied at the same concentrations as found in the Alethea compound and in exactly the same manner as all other experiments, either singly, or in combination with all other components (‘JSA’). Means shown are of 5 replicate plants per treatment ± 1 S.E.
