摘要：

The influence of osmotic effects of aqueous plant extracts on the results of allelopathy bioassays was investigated for four pasture grass species. It was found that allelopathic effects were substantially overestimated when osmotic effects were not taken into account. It is concluded that bioassays using aqueous plant extracts are more realistic when osmotically adjusted control values (with the same osmotic potential as the plant extract being tested) are used.
