Abstract
To explore the allelopathic effects of Koelreuteria bipinnata Franch. Var. integrifoliola (Merr.) T. Chen leaf aqueous extracts on the four turf grasses (Festuca arundinaces, Trifolium repens, Lolium perenne and Agrostis tenuis), the indoor petri dish method was used to study the effects of water extracts from K. bipinnata leaves with different concentrations (12.50, 25.00, 50.00, 100.00 mg/mL) on seed germination rate and seedling growth of the 4 turf grasses. The results showed that the leaf aqueous extracts with the increasing concentrations exhibited inhibitory effects on the seed germination rate, germination index, vigor index, seedling height, root length and fresh weight of four kinds of turf grasses. High concentration (100.00 mg/mL) of leaf aqueous extracts significantly inhibited seed germination and seedling growth of receptor plants. Sensitivities of different turf grass species on K. Bipinnata leaf aqueous extracts were different, T. repens is the most sensitive, but L. perenne is the most insensitive.关键词
