Aromatic compounds and their antioxidant activity of Acer saccharum
Journal of Natural Medicines, 2010A new lignan glycoside, 5-(3″,4″-dimethoxy-phenyl)-3-hydroxy-3-(4'-hydroxy-3'-methoxybenzyl)-4-hydroxymethyl-dihydrofuran-2-one 4'-O-α-L: -rhamnopyranoside (1), with seven known compounds, compound 2, koaburside, icariside E(4), cleomiscosin C, cleomiscosin D, scopoletin, and 5'-demethylaquillochin, were isolated from the EtOH extract of the wood of ...

This chapter describes the sugar maple, which is extraordinarily shade tolerant as it develops layer after layer of thick leafy canopy that casts a dense shade on the forest floor beneath. Unlike less shade-tolerant trees, sugar maples do not self-prune much and retains lower branches.

American Midland Naturalist, 1934
Mr. Mackenzie seems to place undue reliance upon the introductory paragraph of Marshall's Arbustum Americanum, which he quotes. If Marshall intended to merely enumerate the Linnaean species of maples in eastern America he certainly made a mess of the subject and on is forced to the conclusion, here as well as in certain other of his genera, that ...

Botanical Gazette, 1968
A study of dichogamy in Acer saccharum Marsh. (sugar maple) has shown that both protandry and protogyny occur in this species. The two conditions were represented equally in the population investigated. Synchronization of blooming periods of flowers of opposite sexes resulted in reciprocal pollination between trees with different dichogamous conditions.

Herb Distribution in an Acer saccharum Forest
American Midland Naturalist, 1962Plant distribution patterns in a mesic forest in southern Wisconsin were sampled within a 1.71-hectare area and related to ecologic amplitude, microenvironmental differences and species aut- ecology. Of 30 important herb species, seven were significantly non-homoge- neous.

Leaf Tatter in Acer saccharum: An Anatomical Link
International Journal of Plant Sciences, 1995"Leaf tatter" is a type of leaf injury associated with Acer saccharum. The goals of this research were to define symptoms of leaf tatter in A saccharum and to describe morphological and anatomical differences among cultivars exhibiting varying degrees of injury.

The effect of stratification on endogenous cytokinin levels in seeds of Acer saccharum
Planta, 1972Stratification of sugar maple seed resulted in high levels of cytokinins after 20 days. A further increase in the chilling period led to a decrease in cytokinins. Most of the cytokinin activity detected was due to compound(s) that co-chromatographed with zeatin.It is concluded that this increase in cytokinins may result in the breaking of dormancy ...

THE IN VITRO GROWTH OF ACER SACCHARUM AND ACER PENNSYLVANICUM CALLUS TISSUE
Canadian Journal of Botany, 1967The media and conditions for the growth of isolated maple tissues were determined. Tissues isolated from Acer pennsylvanicum and Acer saccharum were grown on a medium containing 25% coconut milk, 2 p.p.m. naphthalene-acetic acid, 2% sucrose, and 2 times the salt concentrations suggested by White and Nitsch.
