Abstract
Premise of research. Ailanthus altissima, an invasive Asiatic tree, is notable for its rapid growth rate (particularly in nutrient-poor soils), root-based cloning, and allelopathy. We investigated whether root exudates from A. altissima stimulate nodulation of red clover, Trifolium pratense, as a mechanism by which the former species may increase nitrogen availability and facilitate its own rapid growth and reproduction.Methodology. To test this possibility and account for the effects of nutrient availability, we conducted a greenhouse experiment that included a full factorial design with 30 T. pratense in each of the following treatments: (1) presence versus absence of A. altissima in leachate source pots, (2) fertilization versus nonfertilization of leachate source pots, and (3) fertilization versus nonfertilization of pots containing T. pratense. Soil leachates acquired from source pots (half of which contained 8-wk-old A. altissima) were applied to pots containing 1-wk-old T. pratense for 7 wk and har...
