Summary

Wheat grains (Triticum vulgare L. var. Lemhi 53) were pretreated for about 6 hours with various solutions. They were then rinsed and planted on filter paper moistened with NaCl solution in petri dishes. Percent germination was measured after 3 days. Germination of water pretreated seeds on 1% NaCl was 8 per cent, while pretreatment with 1% CaCl2. 2H2O resulted in 90 per cent germination on 1% NaCl. Pretreatment with sodium and potassium chlorides enhanced germination only slightly. The beneficial effects of calcium pretreatment could be duplicated only partially by increments of CaCl2 to the NaCl germination medium. Preatreatment concentrations ranging from 1 to 5% CaCl2. 2H2O, and times ranging from 3 to 24 hours were about equally effective. The beneficial effect of pretreatment persisted even though the seeds were subsequently dried and planted several months later. Pretreatment with calcium resulted in about a 25 per cent reduction in Na22 uptake from the germination medium.
