The morphometric and biochemical parameters of the test object (Allium cepa L.) in a single 24-hour treatment with salts of heavy metals (CuSO??? ?? 5H???O and Pb(NO???)???) and aqueous extract of oak silkworm pupae were studied. It was found that in the leaves of treated with salt solutions of copper and lead bulbs, content of TBA-positive substances increased and contents of photosynthetic pigments in leaves decreased. It was revealed that treatment of bubls with salt solution of copper and lead in the entire range of concentrations leads to the inhibition of root growth, reduction of ??-amino nitrogen, and increased content of phenolic compounds. When adding a hydrophilic components of oak silkworm pupae to solutions of salts of copper and lead their toxicity decreased and the studied parameters in many cases have reached the range of control values. The studies can serve as grounds for the investigation of the protective action of an aqueous extract of oak silkworm pupae on plant objects.
