Exciting iron toxicity experiment commenced

Two BSc thesis student have commenced their experimental work on iron toxicity, Fe(II), in wheat growing under waterlogging-simulated conditions in nutrient solution. The pilot experiments showed substantial toxicity of Fe(II) but also a stunning ability to recover as soon as Fe(II) was removed from the solution.

Only hours after Fe(II) was added to the nutrient solution, the roots appeared rusty with heavy deposition of iron plaques. One week of treatment almost killed the plants but a subsequent week of recovery revealed excellent growth of new adventitious roots and even from the seminal roots growth of new fine laterals was observed.

So, what was the Fe(II) concentration? You will have to stay tuned to learn more as I cannot reveals such details at this point in time…
