Abstract:
In order to explore allelopathic effects of garlic bulb aqueous extracts on soybean,the germination rate, germination potential, germination index, root length, hypocotyl length, plant fresh weight, POD activity, SOD activity, CAT activity and MDA content of soybean under different contertrations((0,20,40,80,100 g?L-1 ) treatment of garlic bulb aqueous extracts were determined. Allelopathic effect index and synthetic allelopathic effect were calculated. The results showed that:The garlic bulb aqueous extracts had double allelopathic effects on seed germination and seedling growth of soybean, that promoted it at low concentration and inhibited it at high concentration. When the concentration of the garlic bulb aqueous extracts was 20~40 g?L-1,the seed germination and seedling growth of soybean could be promoted, SOD activity and CAT activity were significantly increased, but MDA content had no obvious change. Under the concentration of extracts of 80~100 g?L-1, it showed obvious inhibitory effect on seed germination and seedling growth, the activity of SOD and POD began to decreased, and MDA content was increased significantly. Besides, indexes of seed germination and seedling growth of soybean showed different sensitivity to garlic allelochemicals. Root length was more sensitive to garlic bulb aqueous extracts, which could be used as an index to measure the allelopathy of garlic to soybean.
