Abstract:
Effects of root exudates (benzoic acid, cinnamic acid, fumaric acid, succinic acid and nicotine) on growth of tobacco seedlings and seed germination was researched by house culture and biological assay. The result showed that, the root exudates could inhibit the growth of tobacco seedlings and seed germination. Different concentrations of benzoic acid, cinnamic acid, fumaric acid, succinic acid and nicotine could inhibit the growth of tobacco seedlings and seed germination too, and the higher the concentration the better effect of the inhibition. There were great differences in the extent of inhibition between the 5 root exudates, benzoic acid> cinnamic acid> succinic acid> fumaric acid> nicotine.
