Chlorophyll a (Chl a), Chlorophyll b (Chl b), Total Chlorophyll (Total Chl) and Total carotenoids (Total Car) contents in the leaf of 28 days old hydroponically grown water spinach plants at different growth conditions. The vertical bars represent SEM (n = 3). Treatment means with different letters imply significant at 5% levels of probability. Treatment description: Cd10 = 10 µM Cd; Cd20 = 20 µM Cd; Cd10MJ2.5 = 10 µM Cd + 2.5 µM MeJA, Cd10MJ5 = 10 µM Cd + 5 µM MeJA; Cd20MJ2.5 = 20 µM Cd + 2.5 µM MeJA, Cd20MJ5 = 20 µM Cd + 5 µM MeJA.
