Only 24% of black seed of halogeton (Halogeton glomeratus (M. Bieb.) C. A. Mey.) germinated 2 weeks after collection in October. After 11 weeks of dry storage germination had increased to 60%. During the additional 12 weeks of pregermination treatment, germination did not vary significantly from 60% except for seed stored moist at low temperatures. Ninety to 95% of moist seeds stored at −6 C for 6 weeks or longer germinated within 48 hr; this rate of germination was superior to that of seed collected in December.
