Sugar maple seeds were soaked in 0.5 percent (w/v) aqueous solutions of acidic and basic compounds varying in molecular weight from 100 to 880. In general, only basic compounds penetrated the seeds. The effects of growth regulators on germination was also tested by soaking seeds and fruits ...
While sugar maple germinated successfully at 7掳 C in the lab, field results suggest that other environmental variables may limit its future establishment as climate changes. Germination of seeds from sugar maple's northern range limit was significantly reduced under warmer conditions, and subsequent ...
Changes in the anatomy, morphology, and stored food reserves of stratifying (5 °C) sugar maple embryos were followed from a strongly dormant state through germination. The correlation of cell division and cell elongation with radicle protrusion was also investigated. No morphological or anatomical ch...

We examined stand structure, sugar maple seed abundance and germination, and sugar maple seedling density and age structure.ResultsSugar maple regeneration was uneven-aged and similar between continuous (south) and discontinuous (north) zones. For the western transect, more filled seeds and more ...
