The cabbage-leaf water extract can inhibit the germination and seedling growth of three receptor crops.

ABSTRACT: Cabbage cultivation has been observed to significantly hinder the growth of subsequent crops in the cold, arid regions of Shanxi Province. To investigate the allelopathic effects of cabbage (Brassica oleracea L. var. Capitata L.) on seed germination and seedling growth of three crops commonly cultivated in such areas, we studied the effects of water extracts from air-dried cabbage leaves on cocozelle, kidney bean, and corn. Experiments were conducted using both petri dish filter paper and pot culture methods to simulate natural conditions. The results indicated that cabbage leaf water extracts at concentrations of 0.01-0.04 g·mL-1 significantly inhibited seed germination. At higher concentrations (0.06-0.08 g·mL-1), the extract markedly suppressed seedling growth in all three crops (p < 0.
