Germination Characteristics of Broadscale: A Possible Saline Alkaline Site Stabilizer

Abstract

Germination of broadscale (Atriplex obovata Moq.), aperennial saltbush, was optimum when the seeds were exposed to light at 10 to 20 degrees C. Germination was suppressed in the absence of light, although very brief exposure to light will overcome this inhibition. Seeds of intermediate size germinate best; gray seeds germinate better than tan seeds. Because of its growth on excessively alkaline, saline sand, and shale soils of the Southwest, as well as its nutritive value and palatability to livestock, broadscale has potential for stabilization of a variety of disturbed sites.
