摘要

Beach pea (Lathyrus maritimus (L.) Bigelow) is a lush green legume which grows along the shores of the island of Newfoundland. It is a circumpolar plant found on both sea shores and the shores of freshwater lakes. Beach pea is a fleshy perennial with an extensive rhizome system. The roots form nodules that contain bacteria (Rhizobium sp.) which provide fixed nitrogen to the legume for incorporation into proteins of the host plant. Beach pea form large persistent stands on beaches and has been studied for its potential as an alternate forage crop. The plants that grow on salt water beaches are exposed to salt water spray inferring some level of salt tolerance in the plant. The objectives of the thesis were to compare salinity effects on beach pea germination relative to other forage crops and to study salinity effects on growth. (Abstract shortened by UMI.)
