Abstract
BONASERA, J., J. LYNCH, anid M. A. LECK. (Biol. Dept., Rider Coll., Lawreiieeville, New Jersey 08648). Comparison of the allelopathic potential of four miiarsh species. Bull. Torrey Bot. Club 106: 217-222. 1979.-A study of allelopathic potential of four species and three soils frolmi a New Jersey freshwater tidal mnarsh was imiade using four bioassay species. Ambrosia trifida leafancd Peltandra virginica leafancd petiole-extracts almost universally decreased germiiination and root growth of lettuce, radish, tomato, and cucumber. Ambrosia stern-extract inhibited growth but not germination. Bidens llaevis leafextract was generally inihibitory, but Bidens stemii-extract only inhibited germnination and growth of lettuce. Typha latifolia leaf-extract was inhibitory to growth, and to radish germination at 24 hrs. Typha rootancd rhizonme-extracts were the least inhibitory. The marsh soils from cattail, ragwveed, anld mnixed vegetation sites at 0 to 5 anid 5 to 10 cm had no effect onl germination of radish or cueumber. Cattail 0 to 5 em soil-extract enhanced cucumber growth at 72 hr aiid radish growvth at 48 hr. Of the bioassay species, lettuce was the most sensitive, radish ancd tomato someewhat less seiisitive, and cucumber the least sensitive.
