Abstract

Sclerocactus glaucus (K.Schum) L.D.Benson (Cactaceae) may have a very low germination rate (2–3%) in the wild. The seeds of this cactus species might need cold stratification and/or scarification to trigger germination. It has been suggested that chipping off a portion of the seed coat or soaking the seed in a bleach solution might increase germination rates for Sclerocactus spp. The purpose of our study was to determine if chipping off the pointed tip of the seed coat of Sclerocactus glaucus seeds and soaking them in a bleach solution would increase germination rates when compared to germination rates of untreated seeds.
