Proteomic Evaluation and Cytotoxicity of Red Maple (Acer rubrum) Leaves
<p>Red maple (<em>Acer rubrum</em>), also known as swamp, water or soft maple, is endemic to eastern and central North America and was widely used as traditional medicine by the first peoples. Commercially, its well-known products include maple syrup and high-quality lumber. The potential medicinal …

A Physiological Investigation of Adventitious Root Initiation in the Genus Acer
… root initiation among species in the genus Acer were investigated. Acer ginnala, A. rubrum and A. saccharinum were easily rooted from softwood stem cuttings. Acer saccharum was moderately difficult to root from cuttings. Acer griseum was the most difficult-to-root species in this study. …

Evaluation of the Antiretroviral Community education and referral (ACER) project - Ng'ombe project site
… Antiretroviral Community Education and Referral (ACER) project was conceptually designed on the basis of the findings from the community consultations, to improve health seeking behaviour, equity of access, adherence to Anti-Retroviral Treatment, prevention for people living with HIV and how to …

The Hormonal Regulation of Growth of Suspension Cultures of Acer pseudoulatanus L. cells
The auxin economy of cell suspension cultures of Acer pseudoplatanus L. has been investigated using physiological and physicochemical techniques. Experiments on the intra- and extra-cellular concentrations of auxins in an auxin-dependent line (OS) of sycamore cells have suggested that endogenous …

Characterization of water stress during cold storage and establishment for Acer platanoides and Crataegus phaenopyrum
… growth, and marketability of bare-root Acer platanoides (Norway maple), Crataegus phaenopyrum (Washington hawthorn) and Prunus x yedoensis (Yoshino cherry). Histological examination of Acer and Crataegus stems was also conducted. Maple and cherry trees were transplanted into pine …

Effects of nitrogen and calcium on photosynthesis and metabolic activity in Acer saccharum in the Catskill Mountains
… other ions that can be harmful to sugar maple (Acer saccharum) rooting systems. The effects of fertilizers on the metabolism and photosynthesis rates of sugar maple are of great interest to both farmers and ecologists. In this study, 12 plots in a 60-year-old sugar maple dominated forest were …

The effects of stress on biomass, soluble sugar concentrations and VA mycorrhizal colonization in sugar maple seedlings (Acer saccharum Marsh.)
Increasing ozone levels (0, 50, 100, 150, 200, 300 ppb) coupled with 80% shading and 50% defoliation were examined for two year-old sugar maple seedlings for one growing season (June-September). Biomass, soluble root carbohydrates and mycorrhizal colonization progressively decreased with increasing …

Signature spectrale des feuilles d'érable à sucre (Acer saccharum Marsh.) en fonction des angles d'éclairement et de visée, 500-800 nanomètres
Le dépérissement des érablières est un problème qui prend beaucoup d'ampleur; on a observé des cas de dépérissement dans toute la zone bioclimatique de l'érablière. L'utilisation de la télédétection est souhaitée pour le suivi et l'étude du dépérissement de l'érablière. L'objectif de cette …

Assessment of Genetic Variation of Acer rubrum L. and Liriodendron tulipifera L. Populations in Unmanaged Forests of the Southeast United States
Acer rubrum L. and Liriodendron tulipifera L. are prolific throughout their ranges in the Southeastern U.S. and also have increasingly important roles in forestry and wood products in this region. The relatively low density and intermediate strength of the wood makes them versatile for use in many …

Acer, a homologue of the human angiotensin-1 converting enzyme, modulates the response of sleep, glycogen storage, lifespan, fecundity and stress resistance to diet in Drosophila melanogaster
… therefore the study of the Drosophila homolog ACER, which is expressed within the fly fat body which is similar in structure to human adipose cells, may highlight a role for ACE in adipose tissue. To investigate the role of ACE-like enzymes in dietary effects on ageing-related and circadian …

The effects of rhizosphere inundation on the growth and physiology of red maple (Acer rubrum L.) seedlings derived from wet and dry sites
Red maple seedlings grown from fruits collected from matched wet and dry sites from three physiographic regions of Virginia were flooded to test whether red maple seedlings derived from wet sites are affected differently by flooding than are seedlings derived from dry sites. Thirteen weeks of soil …

AN INVESTIGATION OF HYDROGEOLOGIC, STRATIGRAPHIC, AND STRUCTURAL CONTROLS ON ACER GRANDIDENTATUM COMMUNITIES IN A KARST LANDSCAPE, OWL MOUNTAIN PROVINCE, FORT HOOD MILITARY INSTALLATION, TEXAS
… communities, including Pleistocene relicts <em>Acer grandidentatum</em>, within karst terrains. These systems exhibit complexly overprinted speleogenetic evolutions within a dynamic groundwater regime resulting from regional climate shifts throughout the Neogene that have been complicated by …

Effects of Experimental Flooding Regimes on the Seasonal Carbon and Nitrogen Budgets of Silver Maple (Acer Saccharinum) and Speckled Alder (Alnus Incana Ssp. Rugosa)
… understand this process, I exposed silver maple (Acer saccharinum L.) seedlings to summer, fall, and continuous (summer + fall) root flooding. Seedlings of speckled alder [Alnus incana ssp. rugosa (DuRoi) Clausen], a dominant N-fixing woody species in northern wetlands, received late spring, …

Site quality factors affecting Acer saccharum, Quercus rubra and Quercus alba abundance and height growth rates in young even-aged stands located in central Missouri
Sugar maple importance has been increasing in Missouri's forest for the previous several decades. Managers have little information to guide them with selecting silviculture treatments for managing this increasingly important species. I examined the effects that soil water, soil nutrients, and …
