ABSTRACT
A mathematical model is presented to estimate the effects of phytochemicals on seed germination. According to the model, phytochemicals tend to prevent germination at low seed densities. The model predicts that at high seed densities they may increase the probability of seed germination and the number of germinating seeds. Hence, the effects are reminiscent of the density-dependent effects of allelochemicals on plant growth, but the involved variables are germination probability and seedling number. The results imply that it should be possible to bypass inhibitory effects of allelopathy in certain agricultural practices and to increase the efficiency of nature conservation in several plant communities.

    Many plant communities are recruitment limited, which may occur because there are either too few seeds to fill available microsites, too few available microsites, or both. In a recruitment-limited, Minnesota, USA old field, we tested among these alternatives in a three-phase study. In phase 1,...

    While goldenrod species are often found to be allelopathic in laboratory settings, its importance in controlling plant community dynamics has been much more difficult to assess. We designed a study to determine whether allelopathy is related to the success of goldenrods in abandoned agricultural...

    This article focuses on the difference between native plants and non-native plants. Non-native plants come from outside the local plant community, unlike native plants. These non-native plants are being grown because of their hardiness. Their seeds can germinate quicke compared to native plants.

    The allelopathic potential of leaf extracts (0.8, 0.1 and 1.2%) of Calotropis procera and Citrullus colosynthis, were studied in laboratory and pot in culture on germination and seedlings growth of maize. The aqueous leaf extracts of C. procera enhanced the germination, but all concentrations of...
