Applied Auxin

Postseverance treatments of wounding, auxin, disbudding, bottom heat, and chilling were examined for their effects on rooting stem cuttings (tips of primary axes) of young Fraser fir (Abiesfraseri (Pursh) Poir.) stock plants. Applied auxin consistently increased rooting percentages and the number and length of roots. Wounding alone did not affect the rooting response, but was beneficial in combination with applied auxin. Certain wounding treatments were better than others. Roots rarely emerged from wound margins and were usually observed at the base of cuttings. Bottom heat enhanced rooting, particularly in combination with wounding + auxin. Removal of lateral buds had a negligible effect on rooting. Following 4 and 8 weeks of artificial chilling, cuttings initially taken in early November rooted well if treated with wounding + indolebutyric acid. However, terminal budbreak was more complete following an 8-week chill. Cuttings taken in late January rooted well without additional chilling. Less chilling was required for rooting than for budbreak.

Factors affecting the greenhouse propagation of firebush (Hamelia patens) by leafy stem cuttings during winter were studied. Without bottom heat (BH), mid-day rooting medium temperature was 22 ± 3 C. About half of the auxin-treated cuttings without BH rooted. Maintaining the rooting medium at 29-39 C increased rooting for auxin-treated cuttings to 96-100% and increased root length and visual rating scores several-fold. Rooting percentage, root length, and visual ratings were consistently high in perlite and low in peat. Stem-tip cuttings and sub-terminal stem segment cuttings with basal stem diameters of 3-5 mm rooted slightly better than stem segment cuttings with basal diameters of 6-8 mm. Stem-tip cuttings not treated with auxin but with BH had rooting percentages of 81-86%. Treatment of stem-tip cuttings with auxin generally yielded 90% rooting or above. Despite this, plants grown from auxin-treated cuttings were indistinguishable from plants grown from non-treated cuttings 2 months after the rooting period. Of the variables studied, BH had the most dramatic effect on rooting of firebush cuttings during winter months.

Rooting Response

Abstract Stem cuttings of five evergreen and vie deciduous taxa were rooted after treatment with 0, 0.1, 0.3 or 0.8% indolebutyric acid (IBA) in talc, or with 0, 0.25, 0.5, 1.0 or 2.0% IBA in 95% ethanol or in 45% propylene glycol. Despite large differences in the rooting response of taxa to carriers and (or) IBA concentrations, propylene glycol-IBA treatments produced rooting in most taxa comparable to those of ethanol-IBA. Root numbers of the 14 taxa increased linearly or curvilinearly with increasing concentrations of IBA dissolved in ethanol or propylene glycol, as did percent rooting of six of the nine evergreen and four of the five deciduous taxa. Talc formulations were generally less effective than IBA in solution at comparable concentrations.

State Of Rest

Terminal stem cuttings from 5-year-old Fraser fir (Abiesfraseri (Pursh) Poir.) stock plants were collected in early fall, when in a state of rest or winter dormancy. Cuttings were subjected to dark storage at 4 °C for 0, 2, 4, 6, 8, 10, or 12 weeks. Following storage, and prior to insertion into a rooting medium, cuttings were subjected to one of two treatments: nontreated, and wounding + indolebutyric acid (IBA). Cuttings received short- or long-days during a 10-week rooting period. Nonchilled cuttings did not root or break bud. High percent rooting occurred after 4–6 weeks of chilling, whereas visible terminal bud activity peaked after a 10-week chill. Rooting was primarily contingent upon IBA treatment and chilling, although long days had a strong promotive effect when cuttings were chilled less than 6 weeks.

Abstract The influence of bottom heat, rooting medium, type of cutting (i.e. terminal vs. subterminal), and commercial auxin formulations on greenhouse propagation of firebush (Hamelia patens Jacq.) by leafy stem cuttings during winter was investigated. Without bottom heat, mid-day rooting medium temperature averaged about 22 ± 3°C (72 ± 5°F). Percent rooting of auxin-treated cuttings without bottom heat was 50% and mean length of the longest root and visual rating scores of root development were low. Maintaining the rooting medium at 29–39°C (85–10 1°F) increased percent rooting for auxin-treated cuttings to 96–100% and increased root length and visual rating scores several-fold. Rooting percentage, root length, and visual rating scores were consistently high in perlite and low in peat moss. Terminal stem-tip cuttings and subterminal stem segment cuttings with basal stem diameters of 3–5 mm (0.13–0.20 in) rooted slightly better than subterminal stem segment cuttings which had basal stem diameters of 6–8 mm (0.25–0.32 in.). Terminal stem-tip cuttings not treated with auxin but with bottom heat had rooting percentages of 81–86%. Treatment of terminal stem-tip cuttings with Rootone F or Wood's Rooting Compound (1:20 or 1:5 dilution) generally resulted in rooting percentages above 90%. Some of the auxin treatments also resulted in increased root length and visual rating scores. Despite these differences, none of the plants grown from auxin-treated cuttings, were distinguishable from plants grown from nontreated cuttings two months after the rooting period. Of the variables studied, bottom heat had the most dramatic effect on rooting of stem cuttings during winter months.

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.

1. A highly successful propagation method is described by which hundreds of side-sprouts are first induced on the parent guava tree. These are later cut and rooted under alternatmg mist, with leaves attached. By using this method it is possible to produce from 500 to 1,000 guava plants from a single 3-year-old tree within 10 months. 2. An experiment is also described and discussed which showed that different rooting media, such as coarse sand and very fine gravel, with Coco-peat, fir bark, Vermiculite, Perlite, and Mexifern, had no appreciable effect on rooting. But treatment with a relatively high concentration, 200 p.p.m., of indolebutyric acid improved and accelerated rooting markedly. Rooting was still further improved if 2 percent of sugar was combined with the indolebutyric acid treatment. 3. The high susceptibility of cuttings under mist to anthracnose disease is mentioned and the usual course of the disease described. Recommendations are suggested for reducing the incidence of this disease.

The natural population of Taxus baccata L. (Himalayan Yew) throughout the Indian Himalayan Region is greatly reduced due to its extensive and reckless exploitation for “Taxol” an anticancer drug. The effects of overexploitation are exacerbated by the species poor regeneration process, slow growth rate and prolonged seed dormancy. Therefore vegetative propagation by branch cuttings seems to be only practical solution for its large scale multiplication. A study was conducted on six candidate trees (CTs) to examine the effect genotype, physiological age of stem, IBA treatment on rooting of Taxus baccata cuttings. Results revealed that rooting behaviour of cuttings was significantly affected by all the factors under study. Among the six CTs studied, CT 2 (from BSI, Shillong) had given the highest rooting response (46.28%). The juvenile cuttings have the higher rooting capacity; however the callusing was more prominent in mature cutting. The influence of IBA treatment was also significant for rooting where 1000 was most effective for stimulating rooting juvenile cuttings and 2000 ppm in mature cuttings.
