Seed germination studies in Atriplex confertifolia (Torr. & Frem.) Wats

Seed gennination of Atriplex confertifolia (shadscale) has been studied sporadically since 1900, with little progress in understanding the mechanisms responsible for seed donnancy or in overcoming these obstacles for the purpose of successfully seeding shadscale in restoration projects. Most work has concentrated on the indurated bracteoles and their role in inhibiting gennination, but no conclusive evidence has been presented to show that the bracts must disintegrate to allow germination. Experiments show that moist chilling offresh seeds for 12 weeks allowed gennination of up to 66 percent offresh fruits and up to 85 percent of 3 year old fruits. No gennination occurred in unchilled fruit. A preliminary trial...
