Growth response of two red maple cultivars (Acer rubrum L. `October Glory' and `Northwood') to styrene lining or copper hydroxide coating of 23.3-liter black plastic containers was evaluated. After the first growing season, plants were left in their original container, repotted into 51.2-liter nontreated containers, or transplanted into the landscape. Copper hydroxide effectively reduced circling of roots of both cultivars at the medium–container interface during the first year of production, but was less effective during the second growing season. Repotting from copper-treated containers into 51.2-liter containers or transplanting into the landscape resulted in more fibrous root development and enhanced root regeneration outside the original rootball relative to transplanting from nontreated containers. However, when copper hydroxide was applied to styrene lining, root regeneration after transplanting was reduced. Roots of plants grown in styrene-lined containers covered the medium–container interface more thoroughly than those in nonlined containers, but height, trunk diameter, and root regeneration were similar. `October Glory' had a larger trunk diameter, more branching, and better root regeneration than `Northwood'.

The influence of N rates and irrigation on shoot growth and trunk diameter were evaluated for red maple (Acer rubrum, L. ‘October Glory’), pin oak (Quercus palustris Muenchh) and dogwood (Cornus florida L. ‘Barton’). Irrigation increased shoot growth and trunk diameter for all 3 species during the first 2 growing seasons. Tree height and trunk diameter at the end of the third growing season were also greater for irrigated trees. Increasing the N levels from 168 to 329 Kg N/ha (150 to 300 lb N/A) resulted in a decrease in trunk diameter the first year and a decrease in shoot growth the second year in ‘October Glory’ maple. No significant differences in oak growth due to N rate were observed. Shoot growth and trunk diameter for dogwood were greater at 329 kg N/ha (300 lb N/A) than at 168 kg N/ha (150 lb N/A) only the first year. Neither height or trunk diameter at end of the third year were significantly increased from applying the higher level of N for any of the genera.

Abstract Two studies were conducted to determine container size and liner (young bare root trees) trunk diameter effects on growth of Acer rubrum L. ‘Franksred’, Red Sunset™ red maple. In experiment 1, maples liners with initial mean trunk diameters of 12.2 mm (0.5 in), 15.9 mm (0.6 in), and 22.3 mm (0.9 in) were potted in 26.5 liter (#7), 37.8 liter (#10), and 56.8 liter (#15) containers and grown for 18 months (2 growing seasons). Height and trunk diameter growth at the end of each growing season were affected by both the initial liner trunk diameter and container size. During year 1, liners with an initial trunk diameter of 12.2 mm (0.5 in) increased 28 and 70% more in height growth compared to liners initially 15.9 mm (0.6 in) and 22.3 mm (0.9) in trunk diameter, respectively. Twenty three percent more height growth occurred with maples in 37.8 liter (#10) and 56.8 liter (#15) containers compared to those in 26.5 liter (#7) containers. Trunk diameter growth increased 50% more with 12.2 mm (0.5 in) liners compared to 22.3 mm (0.9 in) liners. A 25% increase in trunk diameter growth occurred with liners potted in 56.8 liter (#15) compared to 26.5 liter (#7) containers. At the end of the second growing season, final tree size was similar with liners that were initially 12.2 mm (0.5 in) and 15.9 mm (0.6 in) liners in trunk diameter to those initially 22.3 mm (0.9 in) when potted into 37.8 liter (#10) and 56.8 liter (#15) containers. In experiment 2, maple liners with trunk diameters 17.5 mm (0.7 in), 20.5 mm (0.8 in), and 29.0 mm (1.1 in) were potted in container sizes 26.5 liter (#7), 37.8 liter (#10), and 56.8 liter (#15) and grown for 18 months (2 growing seasons). Liners grown in 56.8 liter (#15) containers had 92% more height growth and 48% more trunk diameter growth than with liners in 26.5 liter (#7) containers. At termination, the shoot dry weight was 41% larger with maples in 56.8 liter (#15) containers compared to those grown in 26.5 liter (#7) containers.

Abstract Response of dogwood cultivars (Cornus florida ‘Barton's White’ and ‘Weaver's White’) to styrene lining and copper hydroxide coating of 10.3 liter (#3) black plastic containers was evaluated in 1993 and 1994. After the first growing season, dogwoods were either left in their original containers or repotted into untreated 23.3 liter (#7) containers. Copper hydroxide reduced root circling of both cultivars in containers; however, root dry weight of plants grown in copper-treated containers was reduced during the first season. Copper-treated containers resulted in less growth in height when plants were left in their original container during the second growing season and less trunk diameter growth of plants repotted into 23.3 liter (#7) containers. In the absence of copper, more surface root coverage and less surface root dieback occurred with plants grown in styrene-lined containers. Both cultivars grown the second season in their original styrene-lined containers had greater height increase than those in unlined containers. After being repotted into 23.3 liter (#7) containers, both cultivars originally grown in styrene-lined containers had greater trunk diameter growth than those in unlined containers.

Effects of two post-transplant environments were tested on trees grown in five nursery container sizes to determine differences in initial post-transplant growth. Vitex agnus-castus L., Acer rubrum L. var. drummondii (Hook. & Arn. ex Nutt.) Sarg., and Taxodium distichum (L.) Rich. grown in 3.5 L (#1), 11.7 L (#3), 23.3 L (#7), 97.8 L (#25), and 175.0 L (#45) containers were transplanted in early summer into field plots in College Station, Texas, and Starkville, Mississippi, U.S. Height, trunk diameter, and canopy width measurements were recorded after nursery production and the end of the first growing season to determine initial growth during landscape establishment. Growth of A. rubrum and T. distichum were significantly (P ≤ 0.05) affected by interactions among container sizes and environments, while V. agnus-castus did not demonstrate a difference between environments but were affected by container sizes. Across all species and locations, trees transplanted from smaller container sizes exhibited a greater percent change in growth than the larger container-size trees. Greater percent change in growth measures in the smaller container-size trees during the first growing season may indicate a more rapid establishment time compared to trees from larger containers. Where differential responses to environments occurred, predominantly the beneficial effects of smaller container sizes on post-transplant establishment were accentuated with more stressful establishment conditions.

Abstract Growth of Rhododendron L. ‘Hershey's Red’ (azalea), Magnolia grandiflora L. (magnolia), Ilex × meserveae S.Y. Hu. ‘Blue Princess’ (holly), Pittosporum tobira (Thunb.) Ait. (pittosporum), Gardenia jasminoides Ellis ‘August Beauty’ (gardenia), and Nerium oleander L. (oleander) were evaluated for 8 months in 3.8 liter (#1) containers treated with (+) or without (−) copper hydroxide (Cu) and with (+) or without (−) a styrene lining. Plants were then repotted into 10.3 liter (#3) untreated containers to determine treatment effects on root regeneration and shoot growth. In addition, azalea, gardenia, and holly were planted in the ground to evaluate root regeneration and shoot growth during landscape establishment. All species tested had less root growth at the substrate-container interface at the end of the first growing season when grown in Cu-treated containers. Other growth parameters measured (height, trunk diameter, growth index) varied among species in response to Cu treatment. One growing season (11 months) after repotting into 10.3 liter (#3) containers, all species had less surface root coverage when the original 3.8 liter (#1) container was Cu-treated. Dry weights of newly generated roots outside the original rootball of repotted or transplanted plants were not affected by Cu or styrene treatment, except for a lower root dry weight of holly when previously grown in +Cu containers. After repotting into larger containers, shoot growth in response to Cu was species-dependent. Transplanted azaleas had a lower growth index after transplanting from +Cu containers than from −Cu containers. Growth index of gardenia was increased after repotting into 10.3 liter (#3) containers from 3.8 liter (#1), styrene-lined containers; surface root coverage 5 months after repotting also was increased when plants were previously grown in styrene-lined containers. Oleander, holly, and magnolia previously grown for 8 months in 3.8 liter (#1), styrene-lined containers without Cu all had more surface root coverage after being grown for 11 months in 10.3 liter (#3) containers compared to plants grown in unlined containers.

Abstract Two trials evaluated insecticides for flatheaded borer control and effect on red maple (Acer rubrum L.) cultivar growth over 4 years. Chrysobothris femorata (Olivier) was the only species reared from borer damaged maples during the study. Soil-applied systemic insecticides (acephate, imidacloprid, clothianidin, dinotefuran, and thiamethoxam) and trunk-applied contact insecticides (chlorpyrifos and bifenthrin) were tested. In the 2005 trial, a one-time drench of Allectus (imidacloprid + bifenthrin) or Discus (imidacloprid + cyfluthrin) provided 2 to 4 years of protection with ‘Autumn Flame’ and ‘Franksred’ from C. femorata. Soil-applied experimental imidacloprid tablets prevented borer damage in the third and fourth post-treatment years, but were not as effective as imidacloprid drenches in the first two years. Soil applied acephate tablets, chlorpyrifos (Dursban 4E) trunk sprays, or untreated control plants had borer damage each year, which totaled up to 41.7% damage by year 4 in ‘Autumn Flame’. Trunk diameter growth and tree canopy size was greater with Discus drench or imidacloprid tablet treatments than other treatments. In the 2006 trial, drenches of Allectus, Discus, or Safari 20SG (dinotefuran) applied in May and Discus or Arena 50WDG (clothianidin) drenches applied in March provided complete protection from C. femorata the first year in ‘Fairview Flame’, ‘Franksred’, and ‘October Glory’. Discus (March) drench provided four years of complete protection among the three cultivars, while other neonicotinoid drenches had 3.7–6.3% (Arena March), 3.7–12.5% (Arena May), 0–6.3% (Discus May), 0–10.3% (Safari), and 12.5–20.5% (Flagship) total damage. Ineffective treatments included an experimental imidacloprid gel (7.4–18.8% damage), acephate tablets (18.5–75.0%), Onyx Pro Insecticide (5.1–18.8%), Dursban 2E (11.1–31.3%), one imidacloprid tablet (15.4–43.8%), or untreated plants (32.1–41.0%). This study demonstrates a single application of some neonicotinoid treatments can provide multi-year C. femorata prevention, increased maple trunk growth, and provide borer protection superior to trunk sprays.

Microhabitat environmental conditions are an important filter for seedling establishment, controlling the availability of optimal recruitment sites. Understanding how tree seedlings respond to warming soil temperature is critical for predicting population recruitment in the future hardwood forests of northeastern North America, particularly as environmental conditions and thus optimal microhabitat availabilities change. We examined the effect of soil warming of 5 °C during the first growing season on germination, survival, phenology, growth, and stem and root biomass allocation in Acer rubrum L. (red maple) seedlings. While there was no effect of soil warming on germination or survival, seedlings growing in warmer soils demonstrated significantly accelerated leaf expansion, delayed autumn leaf senescence, and an extended leaf production period. Further, seedlings growing in warmer soils showed larger leaf area and stem and root structures at the end of the first growing season, with no evidence of biomass allocation trade-offs. Results suggest that A. rubrum seedlings can capitalize on soil warming by adjusting leaf phenology and leaf production, resulting in a longer period of carbon uptake and leading to higher overall biomass. The absence of growth allocation trade-offs suggests that A. rubrum will respond positively to increasing soil temperatures in northeastern forests, at least in the early life stages.

Acer rubrum `October Glory' has grown well in field studies across the southeastern United States. However, there is limited information on container production for this cultivar. Our objective was to evaluate first-year growth of container-grown `October Glory' at three locations with dissimilar climates in Georgia and Alabama. Rooted cuttings were planted in no. 3 containers at one location in Apr. 1995. Trees were transported the second week of June to Blairsville, Ga.; Auburn, Ala.; and Tifton, Ga. Trees were grown for 6 months until dormant and were harvested at the end of December. Location had no impact on final plant height increase (Blairsville, Auburn, and Tifton, 59.8, 53.0, and 60.2 cm, respectively). Increases in stem diameter and shoot dry mass were greatest at Tifton (8.4 mm, 17.5 g) and least at Blairsville (6.3 mm, 9.2 g), with Auburn similar to both locations (6.8 mm, 12.2 g). Root dry masses and root: shoot ratios were greatest in Tifton (17.2 g, 0.967), with no differences between Blairsville (4.9 g, 0.508) and Auburn (7.0 g, 0.641). Despite climatic dissimilarities, among locations, producers of container-grown `October Glory' could expect similar growth during the first year throughout Georgia and Alabama.

Pruning Techniques

Branch diameter relative to the trunk diameter (aspect ratio) affected the extent of discolored and decayed wood in the trunk of seedling-propagated red maple (Acer rubrum L.) after branch removal. More discoloration resulted from removing codominant stems than removing branches that were small compared to the trunk. Removing limbs that originated from lateral buds resulted in the same amount of discoloration and decay as removing suppressed limbs that were once the leader. This result provides indirect evidence that a small codominant stem suppressed by pruning techniques designed to slow its growth rate can result in a branch protection zone at the union. There was no relation between the presence of a bark inclusion and decay 4 years after making pruning cuts.

Leaf Nutrient Concentrations

Foliar samples from green and chlorotic red maple trees (Acer rubrum L.) were collected during each of three periods of the growing season, and analyzed for nutrient element concentrations. Compared to green leaf nutrient concentrations, those in chlorotic leaves were statistically different as follows: high P and K, and low Mn in late spring; high N, P, K, Fe, and Zn, and low Mn in mid-summer; high K and Mg, and low Mn in late summer. Considering lowest individual nutrient concentrations per period in green leaves as critical values, most chlorotic leaves were deficient in Mn, a few were deficient in Cu or Zn, and none was deficient in Fe. Using a similar method for identifying excesses, most chlorotic leaves contained excessive K, accompanied by excessive P in mid-summer. Chlorotic leaves with no apparent micronutrient deficiencies were excessively high in some individual or combination of macronutrients, primarily K, but consistently accompanied by P in mid-summer.
