Photinia X Fraseri

Light or heavy wounding applied to stem cuttings of Fraser's photinia (Photinia x fraseri Dress) had little effect on stimulating rooting. The greatest response from wounding was realized when used in combination with a 5000 or 10,000 ppm indolebutyric acid (IBA) solution. Satisfactory rooting, however, was attained by IBA treatment alone.

Ilex Vomitoria

Semi-hardwood or hardwood stem cuttings of Ilex vomitoria Sol. ex Ait. ‘Dare County’ [‘Dare County’ yaupon holly (syn. ‘Virginia Dare’ yaupon holly)] were treated with solutions of the potassium (K) salt (K-salt) of indolebutyric acid (K-IBA) at 0 to 8000 mg liter−1 (ppm). Nontreated semi-hardwood cuttings rooted at 78% whereas, regardless of auxin treatment, hardwood cuttings taken on two dates rooted at 15%. Treatment of cuttings with K-IBA was generally ineffective and resulted in a linear decrease (P ≤ 0.05) in percent rooting of semi-hardwood cuttings.

Stem cuttings of Thuja L. × `Green Giant', consisting of 22-cm terminals or 20-cm laterals, were collected on three dates associated with specific growth stages (softwood, semi-hardwood, and hardwood), and treated with indolebutyric acid (IBA) in 50% isopropanol ranging from 0 to 9000 ppm and placed under intermittent mist. Regardless of cutting type or auxin treatment, cuttings rooted in high percentages at each growth stage. Overall rooting was highest for hardwood cuttings (96%) followed by semi-hardwood (86%), and softwood (85%) cuttings. Semi-hardwood cuttings were the only cuttings in which rooting was affected by IBA or cutting type with the greatest rooting (94%) attained using lateral cuttings treated with 6000 or 9000 ppm IBA. Although an interaction occurred between IBA treatment and cutting type for mean root length of hardwood cuttings, only mean root length of semi-hardwood cuttings was influenced by IBA concentration alone with the greatest length (25 mm) achieved with 6000 ppm IBA. An interaction was noted for root count between cutting type and IBA concentrations for softwood cuttings, whereas IBA and cutting type affected independently root count on semi-hardwood cuttings. Treatment with 9000 ppm IBA resulted in 18 roots per rooted cutting whereas lateral cuttings responded with a mean of 16 roots over all IBA concentrations. Root count on hardwood cuttings was affected by IBA treatment only, with 9000 ppm being optimum (14 roots per rooted cutting).

Abstract Two experiments, one utilizing softwood cuttings and the other semi-hardwood cuttings, were conducted to investigate the influence of growth stage and auxin treatment on rooting four related clones of eastern redbud (Cercis canadensis L.). The four clones were ‘Flame’ (C. canadensis L. ‘Flame’), dwarf white, and two selections (NC99-6-1 and NC99-6-2) of an F1 generation derived from a cross of ‘Flame’ and dwarf white. At each growth stage, rooting responses of the clones varied and were influenced greatly by auxin treatment, demonstrating the variable rooting potential of the genotypes. In both studies, ‘Flame’ rooted well [63% rooting in the softwood study when treated with the potassium (K) salt (K-salt) of indolebutyric acid (IBA) at 5000 mg·L−1 (ppm), 83% rooting when treated in the semi-hardwood study with K-IBA at 10,000 mg·L−1], indicating stem cuttings may be a commercially feasible means of propagation for ‘Flame.’ Softwood cuttings of dwarf white (46%) and NC99-6-2 (75%) rooted best when treated with K-IBA at 15,000 mg·L−1, whereas softwood cuttings of NC99-6-1 rooted best (46%) when treated with K-IBA at 10,000 mg·L−1. Dwarf white and the F1s rooted poorly in the semi-hardwood study.

Abstract Stem cuttings of ‘Carolina Sapphire’ smooth Arizona cypress [Cupressus arizonica var. glabra (Sudw.) Little ‘Carolina Sapphire’] consisting of 30 cm (12 in) terminals or distal [terminal 15 cm (6 in)] and proximal [basal 15 cm (6 in)] halves of 30 cm (12 in) terminals were taken on three dates associated with specific growth stages (semi-hardwood, hardwood, and softwood). Cuttings were treated with indolebutyric acid (IBA) in 50% isopropanol ranging from 0 to 16,000 ppm (1.6%) and placed under intermittent mist. Regardless of cutting type and auxin treatment, cuttings rooted at each growth stage. Overall percent rooting was highest during the hardwood stage (70%), followed by the semi-hardwood stage (44%). Softwood cuttings exhibited the lowest overall rooting (33%). At each growth stage, percent rooting, root count, and root dry weight varied depending on cutting type and IBA treatment. Rooting percentages ≥70% were attained at the semi-hardwood and hardwood growth stages for particular treatment combinations.

Two experiments were conducted for propagation of Quercus robur L. by stem cuttings in Kashmir valley. First experiment which includes: hardwood cuttings were treated with Indolebutyric acid(IBA)having concentrations of 5,000, 10,000, 15,000, and 20,000 ppm in talc and Naphthalene acetic acid (NAA) having concentrations of 500, 1,000 and 1,500 ppm in talc while the second experiment i.e. softwood cuttings were taken and treated with Indolebutyric acid (IBA) having concentrations of 5,000, 10,000, 15,000, 20,000 ppm quick-dipped for 5-seconds and Naphthalene acetic acid (NAA) having concentrations of500, 1,000 and 1,500 ppm dipped for 24 hours and in both (nontreated) as control and placed under mist conditions. It was found that English Oak can be propagated through cuttings and auxin treatment is imperative and Indolebutyric acid (IBA) with concentration of 10,000 ppm showed best results with highest recorded rooting of 51.30 per cent in case of softwood cuttings and for hardwood cuttings also, Indolebutyric acid (IBA) with concentration of 10,000 ppm showed good results with highest recorded rooting of 29.70 per cent. However, control and NAA-treatments in both softwood and hardwood cuttings could not induce rooting at all.

ABSTRACT Propagation by cuttings is an alternative for obtaining citrus rootstocks. The exogenous application of indolebutyric acid (IBA), cutting collection season and genotypes used may affect the rooting and vegetative growth of citrus rootstocks cuttings. Two experiments were conducted to study the influence of these factors. In the first one, semi-hardwood cuttings from the 'Sunki' mandarin hybrids H49 and H77 were collected in the fall and late spring of 2013 and treated with IBA (0 mg L-1, 1,500 mg L-1 and 3,000 mg L-1). For each collection season, a 2 x 3 (two genotypes x three IBA concentrations) factorial scheme was adopted, in a randomized blocks design. In the second experiment, the development of cuttings that rooted in the late spring was evaluated until grafting. In this case, a completely randomized experimental design was adopted, with the hybrids H49 and H77. The IBA treatments positively influenced rooting and number of roots only in the fall collection, peaking at 23.3 % of rooted cuttings. In the late spring collection, rooting was close to 100 %, with the IBA treatment being unnecessary. Around 50 % of cuttings from the 'Sunki' mandarin hybrids were ready for grafting at 14 months after cutting.

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 vegetative propagation of ornamental plants can be accelerated by applying plant growth regulators. Amongst them, the use of auxins, plant hormones with physiological effects on cell elongation and rooting have stood out. Alternatively, the application of humic acids, bioactive fraction of soil organic matter, also results in increases in rooting cuttings of ornamental plants. The objective of this work was to study the growth characteristics and the nutritional contents of croton and hibiscus plants during acclimation of seedlings in response to different concentrations of indolebutyric acid (IBA) and humic acid (HA) applied to cuttings for rooting. The experiment was conducted in greenhouse, and the apical stem cuttings were treated with solutions with concentrations of 0, 250, 500, 1000 and 2000 mg L-1of IBA and 0, 10, 20, 30 and 40 mg L-1 of C from HA. At 45 days of rooting in carbonized rice husk, they were individually transferred to plastic bags of 2.0 dm3 containing a mixture of soil: sand: manure (2: 1: 1) as substrate. At 90 days of acclimation, the plants were collected for measurement of growth and nutritional variables. The results showed that the application of the IBA stimulates the absorption of nutrients and growth of croton cuttings and transplanted hibiscus, contributing to formation of vigorous seedlings. A similar response occurred with the application of HA in hibiscus cuttings

Abstract Four woody plant taxa (‘Sparkleberry’ holly, ‘Mariesii’ viburnum, ‘Shasta’ viburnum, and Red Sunset® maple) were propagated from softwood stem cuttings in a recirculating subirrigation propagation system to evaluate the effect on adventitious root formation of three auxin (Dip-n-Grow®) concentrations [0 (water), 20: 1, or 10: 1] and three medium temperatures [20C (68F), 23C (74F), or 26C (79F)]. All taxa showed a positive rooting response to auxin treatment. Compared to cuttings treated with water, root number of all taxa doubled when treated with the highest auxin concentration (10: 1 Dip-n-Grow® dilution). Length of the longest root of rooted cuttings increased with auxin treatment of two taxa. Medium temperature also affected rooting of all taxa. The intermediate temperature evaluated, 23C (74F), was optimal for all rooting parameters on cuttings of ‘Mariesii’ viburnum, and for root length and percentage rooting on cuttings of ‘Shasta’ viburnum and Red Sunset® maple. A propagation medium temperature of 26C (79F) resulted in the greatest root number on cuttings of ‘Shasta’ viburnum, while 20C (68F) was optimal for root number on cuttings of Red Sunset® maple. Root numbers on cuttings of ‘Mariesii’ viburnum were reduced at 20C (68F) and 26C (79F), which appeared to be sub-and supra-optimal temperatures, respectively, for root initiation. All rooting parameters on cuttings of ‘Sparkleberry’ holly increased with propagation medium temperature. Temperature-auxin interactions were apparent for root number and length on cuttings of ‘Mariesii’ and ‘Shasta’ viburnum. The recirculating subirrigation system was useful for evaluating the basal temperature and auxin dose interactions and was effective for rooting softwood stem cuttings without intermittent mist irrigation.
