Cold Soaking Reduces the Stratification Requirement of Sugar Maple Seeds

Under current laboratory procedures sugar maple seeds are soaked in water overnight and then stratified (stored under cold, moist conditions) for 90 days. Germination is spread throughout the stratification period with initial germination beginning after about 35 days and maximal germination taking place during the period (55 days) between 35 and 90 days of stratification. Webb and Dumbroff (3) showed that most of the stratification period is required for an adequate uptake of water. This study was conducted to see if soaking sugar maple seeds in water for extended periods would reduce their stratification requirement.
