Abstract In order to study the effects of different concentrations of garland chrysanthemum organ water extract on seed germination characteristics of watermelon（Citrullus lanatus）, 0.001, 0.01 and 0.1 g?mL-1 organ water extracts from garland chrysanthemum root, stem and leaf, flower were used to treat watermelon seeds and to test seed germination characteristics. The results showed that different concentrations of garland chrysanthemum root, stem and leaf, flower water extracts could inhibit seed germination of watermelon. The inhibitory effect increased along with the concentration rise. The germinability, germination percentage, radicle quality were all lower than the control. Therefore, 0.001-0.1 g?mL-1 garland chrysanthemum organ water extracts has distinct allelopathy effect on watermelon germination.
