This study was conducted in order to determine the role of the two seed morphs, observed for the first time in a desert population of the widespread Atriplex canescens (Amaranthaceae), in regard to their germination requirements, salinity tolerance and recovery after salt exposure during the seed germination stage. Seeds of the two produced colours (brown and black) were germinated in laboratory conditions under two photoperiods (12/12-h light and continuous dark), three alternating temperature regimes (15/25,...
