Influence of Nitrates on Germination of Seeds under Oxygen Supply of Various Concentrations

[摘要] Seeds were treated with nitrate solution and were germinated on moist filter paper in a dark thermostat kept at 25°C. The germination of seeds was found to be affected by suppling nitrate from outside. Tomato, tabacco, lettuce and radish seeds could be accelerated in germination under the ordinary air and the air with lowerered oxygen concentration when presoaked in 0.02∼0.005 M potassium nitrate solution. The effect of nitrate, however, was not decisive on barley and maize seeds.
