A study looked at how different types of selenium affect a plant called Cardamine violifolia. They found that selenate was the best at helping the plant accumulate selenium, with selenite coming next, and Se yeast being the least effective. The plant could accumulate a lot of selenium, mostly in an organic form. The best concentration of selenate for the plant was 200 mg/L, while selenite at the same concentration could help produce more organic selenium. Overall, selenate was the most efficient at helping the plant grow and maintain its nutrient quality.
