摘要：

American beech (Fagus grandifolia Ehrh.) has two modes of reproduction, propagating both by sexual seedlings and by vegetative suckers. We compare natural levels of parasite-induced leaf damage in the two types of progeny to test the hypothesis that seed reproduction ameliorates losses to various biotic antagonists. As predicted by the parasite-escape hypothesis, we find that seedlings suffer less damage than suckers and that this advantage declines with increasing size of the young tree.
