Description

Saline environments occupy about 15 millions ha in the Mediterranean basin (Le Houerou, 1986). Many of those areas have been traditionally devoted to grazing. Native salt tolerant ecotypes of forage legumes and grasses are increasingly menaced. Overgrazing may lead to local extinction of the most palatable races ; on the other hand, their habitats are decreasing in salt marshes by drainage and farm­land reclamation. Therefore, a coordinated program of survey, evaluation and conservation of salt tolerant plant genetic resources would be desirable in the Mediterranean basin. A project to study the ecology, physiology and nutritive value of salt tolerant annual legumes in the Guadalquivir delta (S.W. Spain) is currently undertaken. In this paper we report preliminary results.
