Abstract Terminal stem cuttings of ‘Brown Velvet’ Southern magnolia (Magnolia grandiflora L. ‘Brown Velvet’) were treated with 0.3% indole-3-butyric acid (IBA) in talc, or 0.5% naphthaleneacetic acid (NAA) quick dip + 0.3% IBA in talc, or 0.5% NAA + 1.0% IB A quick dip. Rooting media included pine bark, perlite, or combinations of bark and perlite at the following ratios: 3:1, 1:1, 1:3 (by vol). Cuttings were rooted in a greenhouse mist bed supplied with bottom heat. Rooting percentage was unaffected by media with the exception of a decreased response in perlite. Root length and secondary root formation was greater with pine bark than with perlite, while the bark/perlite blends provided an intermediate response. Increased auxin concentrations produced more primary roots but reduced formation of secondary roots. However, rooting percentage was not affected by auxin treatment. Results suggest that medium selection is more important than auxin source or delivery method in the rooting of ‘Brown Velvet’ Southern magnolia.

‘Dwarf Burford’ holly (Ilex cornuta ‘Dwarf Burford’) is a significant nursery crop and is widely used in landscapes in U.S. Department of Agriculture hardiness zones 7 to 9. Stem cuttings can be rooted at multiple times during the year, provided cutting wood is sufficiently mature, with auxin treatments traditionally used to encourage rooting. This study was conducted to determine if auxin treatment could be eliminated, thus reducing labor and chemical requirements in the cutting propagation process. In three experiments, terminal stem cuttings of ‘Dwarf Burford’ holly were taken in winter, prepared with and without use of a basal quick-dip in an auxin solution, and rooted in a warm, high-humidity environment. Rooting percentages for nontreated cuttings and cuttings treated with 2500 ppm indole-3-butyric acid (IBA) + 1250 ppm 1-naphthaleneacetic acid (NAA) were similar, while treatment of cuttings with 5000 ppm IBA + 2500 ppm NAA resulted in a decrease in rooting percentage. The number of primary roots and total root length were similar among the three treatments, except in one experiment where total root length was greater with auxin-treated cuttings than with nontreated cuttings. Initial shoot growth responses were variable among the three experiments. The treatment of cuttings with auxin was not required for successful rooting and can be eliminated from the process for winter stem cutting propagation of ‘Dwarf Burford’ holly.

Heller’s japanese holly [Ilex crenata ‘Helleri’ (synonym: Ilex crenata f. helleri)] is a popular landscape plant in U.S. Department of Agriculture hardiness zones 5b to 8a because of its dwarf habit, slow growth rate, and dark green leaves. Plants can be propagated readily by stem cuttings and use of an auxin treatment is generally recommended to promote rooting. This study was conducted to determine if auxin treatment could be eliminated, thus reducing labor and chemical requirements in the cutting propagation process. In three experiments, terminal stem cuttings of Heller’s japanese holly were taken in winter, prepared both with and without use of a basal quick-dip in an auxin solution [2500 ppm indole-3-butyric acid (IBA) + 1250 ppm 1-naphthaleneacetic acid (NAA)], and rooted in a warm, high-humidity environment. Both nontreated cuttings and cuttings receiving a 1-second basal quick-dip in the auxin solution rooted at, or near, 100%. However, treatment of cuttings with auxin resulted in larger root systems on the rooted cuttings, which could allow earlier transplanting into larger nursery containers. No inhibition of new spring growth was exhibited by cuttings treated with auxin in comparison with nontreated cuttings.

Jasminum parkeri Dunn is a narrowly endemic, critically endangered woody ornamental shrub confined to sub-temperate zone of Western Himalayas, and rediscovered from its type locality after a lapse of about 100 years. In the present study, a propagation technique of J. parkeri, using stem cuttings, was established for the first time through application of auxins, namely, indole-3-acetic acid (IAA), 1-naphthaleneacetic acid (NAA), and indole-3-butyric acid (IBA), at varying concentrations ranging from 1000 to 4000 ppm. The highest rooting percentage (98.33% (85.68% ± 4.32)), number of primary roots (36), root length (29.68 cm) and survival percentage (96.67% (83.85% ± 6.16)) were recorded for cuttings treated with 3000 ppm NAA. The phenological comparison between pot plants propagated through seeds and stem cuttings in a naturally ventilated polyhouse revealed a reduction in vegetative and flowering phases in cutting raised plants. Additionally, a noteworthy adaptive behavior of two weeks of early flowering and four weeks of extended flowering (February to October) was observed in plants raised under polyhouse conditions. This method will help in protecting the species from population decline, thereby significantly increasing its potential to be harnessed as an ornamental plant in India. Furthermore, plants grown ex situ will be reintroduced in natural populations.

Stem cuttings of Hydrangea paniculata Sieb., Rosa L. `Red Cascade', Salvia leucantha Cav., and Solenostemon scutellarioides (L.) Codd `Roseo' were inserted into six rooting substrates: monolithic slag [(MgFe)2Al4Si5O18], sand, perlite, vermiculite, Fafard 3B, or fine pine bark. Rooting, initial shoot growth, and ease of dislodging substrate particles from root systems upon bare-rooting by shaking and washing cuttings rooted in monolithic slag were compared to cuttings rooted in the five other substrates. Rooting percentage, number of primary roots per rooted cutting, and total root length per rooted cutting for cuttings rooted in monolithic slag were generally similar to the five other substrates. Particles of monolithic slag were dislodged more readily from root systems by shaking than were the other substrates. Gentle washing removed almost all particles of monolithic slag and sand from the root systems of all taxa and removed almost all particles of pine bark from all taxa except S. scutellarioides `Roseo'. Monolithic slag had a bulk density similar to sand, retained less water than the other substrates, and was similar to perlite, vermiculite, and pine bark in particle size distribution. Our studies indicate that monolithic slag, where regionally available, could provide a viable material for producing bare-root cuttings.

Seven concentrations of IBA and seven concentrations of NAA plus a nonauxin control were tested over three growth stages to determine their effectiveness in promoting adventitious root formation on stem cuttings taken from 3- and 4-year-old stock plants of Fraser fir [Abies fraseri (Pursh) Poir.]. Cuttings were prepared in March (hardwood), June (softwood), or November (semi-hardwood) 2001, treated with auxin concentrations ranging from 0 to 64 mm, and placed under mist. Rooting percentage, percent mortality, number of primary roots, total root length, root system symmetry, and root angle were recorded after 16 weeks. Growth stage and auxin concentration significantly affected every rooting trait except root angle. NAA significantly increased the number of primary roots and total root length. However, auxin type did not significantly affect rooting percentage or percent mortality. The highest rooting percentages (99%) occurred when softwood cuttings were treated with 5 mm auxin, however, semi-hardwood cuttings also rooted at high percentages (90%) and had no mortality when treated with 14 mm auxin. Regardless of auxin type, the number of primary roots and total root length varied in similar patterns across concentration, although, NAA tended to induce a greater response. To root Fraser fir stem cuttings collected from 3- and 4-year-old stock plants, it is recommended that a concentration of 5 mm NAA should be used on softwood cuttings and 14 mm IBA on semi-hardwood cuttings. Chemical names used: indole-3-butyric acid (IBA); 1-naphthaleneacetic acid (NAA).

Mindi besar (Melia dubia Cavanilles) is one of fast growing tree species from family Meliaceae which growing in tropical evergreen forests. The aim of this study was to determine the best combination of medium and growth regulator for vegetative propagation of mindi besar trees. The completely randomized factorial design was used two factors; medium (M) there were two types of media; zeolite (M1) and soil + rice husk (2:1 v/v) medium (M2), the growth regulator (H) had three levels; control (H0), pure coconut water (H1), and Auksin sintetis (H3). The study was conducted at two locations, first at green house with rooting room KOFFCO System and second at seedbed with rooting room containment model (MS). The research at greenhouse using rooting room KOFFCO System showed that interaction of media with growth regulator had a very significant effect on the percentage of fresh cuttings and rooted cuttings and had a significant effect on the number of primary roots. The averages of percentage of fresh cuttings and rooting were 83.3% and 66.7% for M1H2 and 76% and 60% for M2H0. The M2H1 reached 2.9 number of primary roots. At the MS model, the medium factor had significantly different only the number of secondary roots (18.11). The growth regulator factors had significantly different on the percentage of rooted cutting (3.33%), root lenght (10.5 cm) and root dry weight (0.18 g).Key words: containment model, KOFFCO system, Rootone-F, zeolite.

Abstract Twelve Alaska native plants were propagated from softwood and semi-hardwood stem cuttings collected from late June through August. Cuttings of new growth were treated with 0.3% indole-3-butyric acid powder and propagated in horticultural grade perlite and vermiculite (1:1 by vol) under intermittent mist with bottom heat [26C (79F)] in a greenhouse with a minimum night temperature of 15C (59F). After 6 weeks, cuttings were harvested and evaluated for rooting percentage and root quantity. Four species rooted poorly (< 25%) regardless of collection date: Siberian alder (Alnus viridis ssp. fruticosa), silverberry (Elaeagnus commutata), Bebb willow (Salix bebbiana) and shrub birch (Betula glandulosa). Best rooting (> 80%) occurred June 20 for: Beauverd spiraea (Spiraea stevenii), sweetgale (Myrica gale), and thinleaf alder (Alnus incana ssp. tenuifolia). Peak rooting for dwarf birch (Betula nana), feltleaf willow (Salix alaxensis), balsam poplar (Populus balsamifera), Labrador tea (Ledum groenlandicum) and littletree willow (Salix arbusculoides) was early to mid July. During peak rooting times, all successful species developed adequate root quantities for survival following transplanting.

Westerwolds ryegrass was grown in tubes on artificial soil profiles at N rates equivalent to 25, 50 or 100 kg/ha with a water table maintained 70 cm below the soil surface. Average results/plant after 13 weeks at low and high N were: DM yield of tops 5.0 and 14.6 g, water consumption 2660 and 4850 cm2, DM yield of roots 1.4 and 3.4 g, total length of all primary roots 2589 and 3374 cm, number of primary roots 103 and 161, number of secondary roots in topsoil 63 and 83 and in subsoil 71 and 83, and total root surface area 1084 and 1736 cm2. ADDITIONAL ABSTRACT: L. multiflorum plants were grown on sandy soil in asbestos tubes with an inner diameter of 15 cm, and 75 cm high, and supplied with 25, 50 or 100 kg N/ha. The soil water level was maintained at 70 cm below soil level. Top growth 8 and 13 weeks after sowing was progressively enhanced by the 2 higher rates, weight increments amounting to at least 72 and 188 %, respectively. These growth increases were accompanied by augmented water consumption, as well as root growth and numbers. (Abstract retrieved from CAB Abstracts by CABI’s permission)
