Winterfat (Ceratoides lanata (Pursh) J.T. Howell, syn. Eurotia lanata (Pursh) Moq., syn. Krascheninnikovia lanata Gueldenstaedt) seeds possess an after-ripening requirement to break dormancy. Germination responses of winterfat seeds to ethanol, gibberellic acid (GA3), citric acid and sodium nitrate (NaNO3) were tested in the laboratory to determine their ability to break dormancy. Ethanol, GA3 and citric acid promoted, while NaNO3 inhibited germination. Ethanol promoted fast and synchronous germination. Promotion of germination by GA3 or citric acid was weak during the test period. Citric acid damaged the radicles of seedlings. Soaking winterfat seeds in 600 to 1,000 mM ethanol for 4 to 8 hours is recommended, as...

Sodium content of utricles, utricle bracts, testa, and embryo was determined for Sarcobatus vermiculatus. Immediately after germination, seedlins were grown in H2O, 330 mM NaCl, or 225 mM Na2SO4 solutions, and Na+ content was determined. Sodium content of utricles averaged 38 900 [mu]g[middle dot]g-1, with highest concentrations in bracts (53 100 [mu]g[middle dot]g-1), and lowest concentrations (1843 [mu]g[middle dot]g-1) in embryos. Sodium concentration of washed embryos averaged 954 [mu]g[middle dot]g-1. Seedlings germinated from debracted utricles and grown 24 h in distilled H2O contained 2965 [mu]g[middle dot]g-1 Na+. The Na+ content of seedlings germinated and grown 24 h in NaCl or Na2SO4 solutions averaged...
