Allelopathic effects of decomposed garlic stalk on different receiver vegetable crops

摘要：

The experiment was carried out to examine the allelopathic effects of decomposed stalk of three garlic cultivars on the growth of the receiver vegetable crops: namely tomato, Chinese cabbage, lettuce, carrot, cucumber and hot pepper in a pot trial. The results showed that the three garlic cultivars showed different allelopathic effects and the same cultivar also showed various results upon different receiver vegetable crops. The activities of protective enzyme SOD in receiver vegetable crops appeared first increased and later on decreased with the increasing content of decomposed garlic stalk. The MDA contents in the receiver vegetable crops showed an increasing trend. There was no apparent regularity on POD and CAT contents. In general, the decomposed stalk of three garlic cultivars showed allelopathic inhibitory effects on all the index of carrot and lettuce, but promotion effects on Chinese cabbage. Therefore, the optimal successive crop for garlic was thought Chinese cabbage among all the receiver vegetable crops in this experiment.
