I've grown kenaf plants at four different Cd concentrations: 0, 100, 250, and 400 uM. Using SPAD, I measured the content of chlorophyll in the third leaf from the top. Even though there is a noticeable decrease in plant growth under Cd stress compared to the control, I have noticed an increase in chlorophyll content under all Cd treatments compared to the control. Please assist me in interpreting these results. I grew plants in a hydroponic culture tray with three replicates, each tray containing 12 plants. I chose three plants from each tray to test the chlorophyll content.
May be priming with metal treatments increase the chlorophyll Biosynthesis in the leaves just like seed priming with any biotic stress or abiotic stress improve the seed germination percentage
