BREEDING SYSTEMS AND FECUNDITY IN THE AMERICAN GINSENG, PANAX QUINQUEFOLIUM (ARALIACEAE)

Abstract

American ginseng is self‐compatible with fecundity among bagged inflorescences equivalent to (Missouri) or greater (New York) than that observed for nonbagged inflorescences. Population differences in flowering time and synchrony, protandry, autogamy, xenogamy, and fecundity, imply major genetic divergence in the species.
