The stimulative action and detoxifying effect of selenium on garlic growth under cadmium stress were investigated. Selenite treatment can promote mitosis of garlic root-tip cells and growth of roots and seedlings. Garlic has a strong ability to accumulate the selenium from soil, and selenium content was greatest in garlic seedlings. Addition of selenite at a concentration of 2.0 μg kg−1 in soil could decrease cadmium content in garlic and protect the seedling growth. The selenium has been shown to have an effective protective role on garlic growth under cadmium stress.
