以4种牧草为试材，研究了植物浸提液的渗透效应对化感作用生物测定结果的影响。结果发现，化感作用被大大高估时，渗透效应不考虑在内。它的结论是，使用含水植物提取物的生物测定是更现实的，当使用经调整的控制值（具有相同的渗透势的植物提取物被测试）。
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.
