Abstract:

Atriplex prostrata (Chenopodiaceae) is a salt tolerant plant species that is widely distributed in inland and coastal marshes of the Unites States and Europe. Atriplex prostrata (Chenopodiaceae) seed germination decreased with an increase in salinity and few seeds germinated at 300 mM NaCl. Fusicoccin (5 mM), ethephon (10 mM), and nitrogenous compounds (nitrate 20 mM and thiourea 10mM) were able to counteract the inhibition produced by salinity treatements. Thiourea was most effective in reversing the inhibitory effects of salinity on the germination of A. prostrata seeds.
