Billy Sale, Califonia Botanic Garden California Botanic Garden (CalBG) is in the process of seed bulking three rare species of Atriplex from populations originating in southern California. Atriplex coronata var. notatior (G4T1), Atriplex parishii (G2G3) and Atriplex serenana var. davidsonii (G5T1). To better inform the project, propagation trials were performed prior to seed bulking in order to examine germination pretreatments. Gibberellic acid was identified as the most effective […]
