    Abstract: Stem cuttings of Buxus sinica var. insularis ‘Wintergreen’, Elaeagnus x ebbingei, Ficus benjamina, Gardenia augusta ‘Radicans’, Ilex glabra ‘Nigra’, Ilex vomitoria ‘Nana’, Juniperus conferta ‘Blue Pacific’, Ternstroemia gymnanthera, and Trachelospermum asiaticum were inserted into a stabilized organic rooting substrate (plugs comprised of peat and a polymer binder) that had been soaked in water, aqueous solutions of K-IBA (15 to 75 ppm), or K-IBA + K-NAA (15 ppm + 7.5 ppm to 60 ppm + 30 ppm). Rooting and initial shoot growth responses were compared with cuttings receiving a basal quick-dip in K-IBA (1000 ppm) or K-IBA + K-NAA (1000 ppm + 500 ppm). Rooting percentage, number of roots per rooted cutting, and total root length per rooted cutting for cuttings rooted in auxin-treated plugs were similar to or greater than cuttings receiving a basal quick-dip; lesser results were obtained in a few cases with K-IBA + K-NAA. Percent of rooted cuttings with new shoots and shoot length per rooted cutting for cuttings rooted in plugs treated with K-IBA were mostly similar to cuttings receiving a basal quick-dip in K-IBA, while cuttings rooted in plugs treated with K-IBA + K-NAA exhibited similar or lesser results compared to cuttings receiving a basal quick-dip in K-IBA + K-NAA.

    Abstract: 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.

    Details
    In: HortTechnology, American Society for Horticultural Science, Vol. 14, No. 4 ( 2004-01), p. 479-483
    Abstract: In five experiments, singlenode cuttings of `Red Cascade' miniature rose ( Rosa ) were treated with a basal quick-dip (prior to insertion into the rooting substrate) or sprayed to the drip point with a single foliar application (after insertion) of Dip `N Grow [indole-3-butyric acid (IBA) + 1-naphthaleneacetic acid (NAA)], the potassium salt of indole-3-butyric acid (K-IBA), or the potassium salt of 1-naphthaleneacetic acid (K-NAA); a single foliar spray application of Dip `N Grow with and without Kinetic surfactant; or multiple foliar spray applications of Dip `N Grow. Spray treatments were compared with their respective basal quick-dip controls {4920.4 μ m [1000 mg·L -1 (ppm)] IBA + 2685.2 μ m (500 mg·L -1 ) NAA, 4144.2 μ m (1000 mg·L -1 ) K-IBA, or 4458.3 μ m (1000 mg·L -1 ) K-NAA}. Cuttings sprayed with 0 to 246.0 μ m (50 mg·L -1 ) IBA + 134.3 μ m (25 mg·L -1 ) NAA, 0 to 207.2 μ m (50 mg·L -1 ) K-IBA, or 0 to 222.9 μ m (50 mg·L -1 ) K-NAA resulted in rooting percentages, total root length, percent rooted cuttings with shoots, and shoot length similar to or less than control cuttings. Exceptions were cuttings sprayed with 0 to 2.23 μ m (0.5 mg·L -1 ) K-NAA, which exhibited shoot length greater than the control cuttings. Addition of 1.0 mL·L -1 (1000 ppm) Kinetic organosilicone surfactant to spray treatments resulted in greater total root length and shoot length. Repeated sprays (daily up to seven consecutive days) had no or negative effects on root and shoot development.

    In: HortScience, American Society for Horticultural Science, Vol. 40, No. 3 ( 2005-06), p. 884d-884
    Abstract: Stem cuttings of golden euonymus ( Euonymus japonicus `Aureo-marginatus'), shore juniper ( Juniperus conferta `Blue Pacific'), white indian hawthorn ( Rhaphiolepis indica `Alba'), and `Red Cascade' miniature rose ( Rosa `Red Cascade') were successfully rooted in plugs of a stabilized organic substrate that had been soaked in aqueous solutions of the potassium salt of indole-3-butyric acid (K-IBA) at 0 to 75 mg·L –1 before inserting the cuttings. Cuttings were rooted under intermittent mist in polyethylene-covered greenhouses with rooting periods appropriate for each species. Rooting percentages showed some increase with increasing auxin concentration with juniper cuttings, but were similar among treatments for the other three species. Number of roots per rooted cutting increased with increasing auxin concentration with cuttings of juniper, Indian hawthorn, and rose, and was greatest using around 60 mg·L -1 K-IBA for cuttings of juniper and Indian hawthorn and 30 to 45 mg·L -1 K-IBA for cuttings of rose.

    Abstract: In an effort to compare yield and time required to remove substrate from roots of liners, Ophiopogon japonicus and Ophiopogon japonicus ‘Nana’ (lilyturf) bare root bibs were potted into 100% aged pine bark, 8: 2 (v: v) pine bark: peat moss, 100% perlite, 100% fine grade Profile™ porous ceramic (Profile™ products LLC, Buffalo Grove, IL), or 100% course grade Profile™ porous ceramic. In a second study Ophiopogon japonicus was potted into 100% aged pine bark, 100% 3/16-inch HydRocks® (Big River Industries Alpharetta, GA), fine grade 100% Profile™, 100% perlite, 100% sand, 8: 2 (v: v) pine bark: peat moss, and 3: 1 (v: v) 3/16 HydRocks®: sand. In the second study, fine grade Profile™ produced the highest number of total bibs per container and bib production was similar to 8: 2 pine bark: peat moss. HydRocks® was similar to pine bark in total bibs per container but was more efficiently removed from roots. Removal of the HydRocks® substrate from plant roots required 50% less time than removal of pine bark: peat moss substrate and 51% less time than removal of pine bark substrate. HydRocks® took 23% less time to remove from roots than fine grade Profile™. Results indicate that clay materials such as HydRocks® and Profile™, when compared to conventional substrates can provide suitable yields while also decreasing labor cost by decreasing time to bare-root.

    Abstract: Growth patterns of seven red maple (Acer rubrum L.) and three Freeman maple (Acer x freemanii E. Murray) cultivars grown in containers in Alabama were evaluated using monthly destructive harvests. The effectiveness of a growth modeling technique not previously described is demonstrated using the data presented for both the Freeman maple (red maple xsilver maple interspecific cross) and red maple categories. Freeman maple cultivars ‘Armstrong’, ‘Celzam’ (Celebration™), and ‘Jeffersred’ (Autumn Blaze™); and red maple cultivars ‘Autumn Flame’, ‘Fairview Flame’, ‘Landsburg’ (Firedance™), ‘Franksred’ (Red Sunset™), ‘Olson’ (Northfire™), ‘Northwood’, and ‘October Glory®’ were studied. Uniform liners of each cultivar were planted in 9.1-liter (#3) containers in March 1996. More than 75% of seasonal height and diameter growth was complete for most cultivars before mid-August, while only 25% of root growth had occurred by the end of August. The remaining 75% of root growth occurred from August through November. The greatest overall growth (based on height, diameter, and root growth increase) was for ‘Autumn Flame’ and ‘October Glory®’, both red maple cultivars; and Freeman maple cultivars ‘Celzam’ and ‘Jeffersred’. The least overall growth (based on height, diameter, and root growth increase), was for red maple cultivars ‘Northwood’ and ‘Landsburg’.

    In: Journal of Environmental Horticulture, Horticultural Research Institute, Vol. 28, No. 2 ( 2010-06-01), p. 107-116
    Abstract: WholeTree (WT) and clean chip residual (CCR) are potential new nursery substrates that are by-products of the forestry industry containing high wood content. Initial immobilization of nitrogen is one concern when using these new substrates; however the addition of composted poultry litter (CPL) to substrates containing high wood content could balance initial nitrogen immobilization and provide an inexpensive fertilizer source for growers. This study evaluated five woody nursery species being grown in WT, CCR, and pinebark (PB) with the addition of CPL or peat as a substrate amendment. Results indicate that these species can be grown successfully in WT and CCR substrates 6: 1 (by vol) with CPL. Use of CPL in WT and CCR substrates may provide an alternative to traditional PB plus peat based combinations in container plant production while providing poultry producers an environmentally sound means of waste disposal.

    In: Journal of Environmental Horticulture, Horticultural Research Institute, Vol. 21, No. 3 ( 2003-09-01), p. 131-136
    Abstract: Research was conducted to determine whether a foliar spray application of the commercial root-promoting formulation Dip 'N Grow® [10,000 ppm indole-3-butyric acid (IBA) and 5,000 ppm 1-naphthaleneacetic acid] or the potassium (K) salt of IBA (K-IBA) would be as effective as a basal quick-dip for rooting stem cuttings of selected ornamentals. Cuttings of Chrysanthemum pacficum sprayed with Dip 'N Grow® at 50 + 25 ppm IBA + NAA or K-IBA at 0 to 50 ppm showed generally similar root development measures compared to a basal quick-dip; an exception was 10 ppm K-IBA which produced greater total root length. Cuttings of Forsythia x intermedia ‘Lynwood Gold’ typically did not differ in root development under the two application methods, but cuttings sprayed with Dip 'N Grow® at 0 + 0 to 10 + 5 ppm IBA + NAA exhibited greater shoot growth 80 days after sticking (insertion into the rooting substrate) than cuttings receiving a basal quick-dip. Root and shoot development measures were similar or lower for cuttings of Abelia x grandiflora, Hydrangea paniculata, and Lagerstroemia (indica x fauriei) ‘Natchez’ sprayed with auxin compared to a basal quick-dip.

    Abstract: In 1991, a cooperative project with the U.S. National Arboretum in Washington, D.C., was initiated in Tifton, Ga. (USDA hardiness zone 8a) to evaluate red maples ( Acer rubrum L.) potentially suitable for the coastal plain region of the southeastern U.S. Greatest annual height growth across all cultivars over 6 years was for `Alapaha', a seedling selection from southern Georgia with annual height growth of 35 inches (88.0 cm), and several seedling selections from northern Florida with annual height increases in excess of 33 inches (86.0 cm). Selections showing the least average annual height growth were NA-56024 and NA-57772 (`Red Rocket'). For commercially available cultivars, the most dependable for fall color in Tifton was `October Glory'®. In addition, two new selections from the National Arboretum have also shown excellent fall color—`Somerset' and `Brandywine'.
