The impact of competition and allelopathy on the trade-off between plant defense and growth in two contrasting tree species

Frontiers in Plant Science, 2016
In contrast to plant-animal interactions, the conceptual framework regarding the impact of secondary metabolites in mediating plant-plant interference is currently less well defined. Here, we address hypotheses about the role of chemically-mediated plant-
