Physiological Characteristics of Sugar Maple and Implications for Successful Planting

Investigations of the physiology of sugar maple seedlings have partially defined the phenological patterns associated with (1) root growth, (2) dormancy and budbreak, (3) changes in carbohydrate reserves and (4) the activity of endogenous hormones. Results are interpreted and discussed in relation to the problem of establishment of sugar maple seedlings on openfield sites in southern Ontario. The need to produce seedlings with the physiological characteristics, and in the developmental stage, most favorable to growth of a vigorous root system at time of planting is stressed. Future research is suggested.
