Effects of Sediment Nitrogen Availability and Plant Density on Interactionsbetween the Growth of Hydrilla Verticillata and Potamogeton Americanus. Aquatic Plant Control Research Program

摘要

This study examines the growth of Hydrilla verticillata (L.f) Royle andPotamogeton americanus C. and S. on both nitrogen-poor and nitrogen-rich sediments and assesses the nature and degree of interspecific interactions between the two species. Extensive greenhouse experiments conducted from May through July 1989 employed sediments differing initially only in sediment
