Do all plants produce antioxidants on their own? I need one type of plant that doesn't if there is one. It doesn't have to be a vegetable or fruit, just a plant. Thanks for your help.

Thanks for the replies. Would paraquat be able to be used in this situation though, where tissue isn't used? I'm using water, the free radical, an antioxidant, and the seeds. John, so I can use any free radicals such as galvinoxyl and it will create oxygen free radicals? Will the free radicals stay in the solution so they'll effect the seeds? Thanks for all the help.

I was planning on using the oxygen free radical, but how would I make it present so that it would affect the seeds and solution?

Can everyone please add their thoughts on how to supply free radicals to an artificial environment. The experiment is the effects of antioxidants and free radicals on seed germination. I had 10 mL of hydrogen peroxide (free radical), the antioxidant, and thirty radish seeds in a petri dish, and observed the amount of seeds that germinated. Would there be an alternate way to supplying a free radical for this experiment? Doesn't matter if I have to change the environment (petri dish) to something else, as long as I get the free radical. I was thinking possibly electrolysis to obtain the oxygen free radical, but how would I maintain the oxygen free radical in the petri dish with the antioxidant (liquid form) and radish seeds? Thanks everyone.
