Dormant stem sections from three individuals each of Acer rubrum (red maple) and A. saccharium (sugar maple), and three clones of Juglans nigra (eastern black walnut) were collected from lower lateral branches of trees at least 30 years old. The stem sections were cut into 50-cm-long segments and placed horizontally in soilless media in a greenhouse. Two experiments were conducted to determine which treatments were most efficient for the production and elongation of epicormic shoots from latent buds below the bark. The first experiment consisted of a factorial arrangement of two levels of shading (not shaded or covered with 48% Saran shade cloth) and two levels of flooding (not flooded or flooded to a depth of 1/3 to 1/2 the diameter of the stem sections). Flooded treatments contained 0.025% NaClO to control microbial growth. The second experiment consisted of three media treatments: perlite, vermiculite, or a 1 perlite: 1 vermiculite (by volume) medium. No stem segments of any species in flooded treatments produced softwood shoots. Neither shading nor media treatments affected shoot number or length for any of the species. Additional sugar maple segments collected after budbreak produced more and longer shoots than those collected while dormant.

Relative water demand, RWD, of 2-year-old containerized seedlings of red maple (Acer rubrum L.), sugar maple (A. saccharum Marsh.), silver maple (A. saccharinum L.), Norway Maple (A. platanoides L.) and boxelder (A. negundo L.) was determined by comparing potential evapotranspiration rates and actual water consumption values with growth rates for each species. Based on differences in growth rate, each species was determined to be either fast growing (red maple, silver maple, boxelder) or slow growing (sugar maple, Norway maple). Fast growing species used the most water over the 3-month experimental period (June-August), and had the higher RWD. The actual irrigation demand for each species was closely correlated with monthly potential evapotranspiration rates as determined by the Thornthwaite equation.

Vegetative shoots were forced in the greenhouse from excised stem (branch) sections of dormant Japanese maple (Acer palmatum Thunb.), red maple (Acer rubrum L.), and sugar maple (Acer saccharum Marsh.). Softwood shoots generated in this way were used as stem cuttings in a subsequent adventitious rooting study. Data indicate that maple shoots can be forced using this technique, but that both the percentage of stem sections forming shoots and the number of shoots produced are highly variable among both species and clones. Whereas Japanese and red maple formed shoots on >50% of stem sections, shoots were generated on only 20% of sugar maple stem sections. Significant variability was also observed in rooting response, with red maple shoots rooting at much higher percentages (60%) than either Japanese maple (26%) or sugar maple (15%).

Abstract Red maple (Acer rubrum L. ‘Franksred’) and sugar maple (Acer saccharum Marsh. ‘Green Mountain’) trees were grown in a 56 liter (15 gal) pot-in-pot system for two years. During the second year of production, root growth was observed through observation plates fitted into the container sidewalls, and shoot extension was periodically measured. Root growth began in early March, approximately one month before budbreak for both species. Root growth dramatically slowed down at the onset of budbreak, but quickly resumed and was concurrent with shoot elongation. Root growth slowed dramatically in the fall when substrate temperatures dropped to 5–7C (40–45F). Root growth stopped during the winter for red maple, but some nominal root growth continued throughout the winter for sugar maple. Red maples had over 5 times more total root length against observation plates at the end of the experiment than sugar maples.

Sapling Density

Shade-tolerant mesophytic tree species tend to dominate the understories of present-day oak–hickory and mixed-hardwood forests in the eastern United States. We quantified the sapling density associations with abiotic and biotic variables for three important mesophytic species: red maple (Acer rubrum L.), sugar maple (Acer saccharum Marsh.), and American beech (Fagus grandifolia Ehrh.) in southeastern Ohio. In this study, we sampled 165 permanent plots in oak-dominated, topographically diverse, mature (>90 years old), second-growth forests following a time span of 21–25 years (1993–1995 and 2016–2018) between samples on the Athens and Marietta units of the Wayne National Forest. Our models showed that sugar maple was strongly associated with high pH soils and red maple was strongly associated with low pH soils. Additionally, red maple was associated with upper slope positions and older stands, while American beech was associated with lower slopes, northeasterly aspects, and northeast-facing upper slopes. Basal area of competing species, solum depth, and management unit were not significantly related to sapling density for our focal species. American beech sapling density doubled between the two sampling periods, while densities of both maple species declined by half. Our results will help scientists and managers by providing insight into potential future composition of currently oak-dominated forests in areas without active management intervention.

Micropropagation studies were conducted to determine the best methods to achieve axillary shoot proliferation for adult Acer rubrum (red maple) and A. saccharium (sugar maple). The first experiment was conducted to compare the effects of 0.001, 0.01, 0.1 μM, 1 μM, and 10 μM thidiazuron (TDZ) using Driver-Kuniyuki-Walnut medium (DKW). The second experiment was conducted to examine the effects of DKW, Woody Plant Medium (WPM) and Long and Preece (LP) media in factorial combination with 0.01 and 0.1 μM TDZ. The third experiment was conducted to study the transfer timing (14 or 28 days) and the media solidification (agar-solidified or stationary liquid) on sugar maple. Both red maple and sugar maple explants on DKW with 0.1 μM TDZ produced the most and longest axillary shoots; however, sugar maple produced fewer axillary shoots than red maple. Red maple explants produced the most callus on DKW with 10 μM TDZ and the least on DKW with 0.001 μM TDZ. Sugar maple explants produced more shoots when explants were placed horizontally and transferred every 14 days than when placed vertically or transferred less frequently.

In southern Quebec, red maple (Acer rubrum. L.) constitutes more than a third of the merchantable wood in certain administrative private forest units. Dendrometrical and ecological surveys of red maple stands were conducted in Drummondville plain area. The study has shown that the phytosociological association criteria contributed significantly to the prediction of dominant height (the dendrometrical variable used as an indice of site quality) in relation to age at breast height (1.3 m). The three studied associations, the red maple-sugar maple association (humid mesotrophic sites), the red maple-black ash association (mesic sites) and the red maple-wild holly association (oligotroph humid sites) differ significantly as to their height growth pattern. On the basis of these associations, three empiric production tables where produced. The yield at 50 years (breast height age) in the three sites qualities amount respectively to 179, 148 and 108 m3 per hectare. Key words: Acer rubrum.

Stem Quality

Northern hardwood trees display a wide variety of stem forms and defects, which can substantially reduce their financial value and also complicate their silviculture. While attributes of stem form and defect have been incorporated into tree classification systems, their ability to assess product value and recovery in standing trees has not been adequately tested. To address this issue, we classified stem form and risk using a system developed by the Northern Hardwoods Research Institute (NHRI) for four species across several locations in Maine, New Hampshire, and New Brunswick: sugar maple (Acer saccharum Marsh.), red maple (Acer rubrum L.), yellow birch (Betula alleghaniensis Britton), and northern red oak (Quercus rubra L.). Using these data, we (i) quantified interspecific and regional variation in stem form and damage, (ii) related potential sawlog recovery to tree size, form, and risk, and (iii) compared the efficacy of the NHRI system with a commonly used classification system and a continuous measure of stem quality. High variation in both stem form and damage among the species was found, with red maple showing the largest range. A simplified NHRI system including three form classes proved to be sufficient in differentiating sawlog potential in individual trees, while a model using a continuous measure of stem quality (estimated merchantable sawlog height) performed best.
