Germination of Sweetgum in Response to Temperature, Moisture Stress, and Length of Stratification
Both total germination and rate of germination of sweetgum seed increased as temperatures were raised from 60-75 to 85-100°F. Increases in osmotic stress lessened total germination and rate of germination and 15 atmospheres of stress completely inhibited germination. Raising the temperatures decreased the influence of osmotic stress, and lengthening the stratification time diminished both temperature and osmotic effects.
