Synopsis A laboratory technique is described for evaluating the winter‐hardiness of alfalfa. Seeds were germinated in solutions of sodium chloride and sucrose having known osmotic pressures. As osmotic pressures were increased the rapidity and amount of germination decreased, however, the decrease was more marked in the seed of hardy varieties.
