We assessed adventitious root formation on stem cuttings of mountain fly honeysuckle [Lonicera villosa (Michx.) Schult.] in separate experiments using overhead mist and subirrigation systems. The concentration of applied potassium salt of indole-3-butyric acid (K-IBA) and the proportions of coarse perlite and milled peatmoss in the propagation medium were varied within both systems. Across treatments, 98% of cuttings in the overhead mist system and 85% of cuttings in the subirrigation system produced roots. In the overhead mist system, root volume, root dry weight, and number of root tips were greatest among cuttings treated with 4000 to 12,000 mg·L−1 K-IBA and stuck into 100% perlite. In the subirrigation system, root dry weight was not significantly affected by K-IBA concentration, but the greatest root volume and number of root tips were produced by cuttings treated with 8000 or 12,000 mg·L−1 K-IBA and stuck into 100% perlite. Despite the natural affinity of mountain fly honeysuckle for moist, organic soils, all of the 18 rooted cuttings we planted in a landscape trial survived and grew appreciably with minimal care over 2 years in a mineral field soil. We conclude that cuttings of mountain fly honeysuckle can be propagated readily by overhead mist or subirrigation, that root system quality is improved substantially by increasing K-IBA concentration and using coarse perlite without peatmoss, and that mountain fly honeysuckle can be grown in typical horticultural landscapes.

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.

Rooting Response

Stem cuttings of Arbutus andrachne L. were taken from basal or terminal portions of branches in October and treated with acid or salt forms of IBA or NAA at several concentrations. Also, the effects of wounding and propagation medium were assessed. Auxin was necessary for root formation, IBA acid being most effective. In general, salt forms of IBA and NAA were less effective than acid forms. Concentration of auxin had a significant effect on rooting regardless of auxin type or chemical form. The greatest rooting percentage, root number, length, and fresh and dry weights were exhibited by basal cuttings treated with 24 mm IBA. Position of the cutting on the branch did not affect rooting except when the IBA acid form was used; basal cuttings were then superior to terminal ones. Wounding, by making two opposite longitudinal incisions at the base of the cutting, increased rooting. The propagation medium had a significant effect on adventitious root formation, which was enhanced with increasing perlite percentage in the medium up to 100%. Chemical names used:1H-indole-3-butyric acid (IBA); α-naphthaleneacetic acid (NAA).

Mature cladodes of prickly-pear cactus (Opuntia amyclaea Tenore. cv. Reina) were treated with five wounding methods and four concentrations of potassium salt indolebutyric acid (K-IBA) to stimulate adventitious root formation. K-IBA from 4144 to 41,442 μm (1000 to 10,000 mg·L-1) increased root number and root dry weight; however, root length was decreased at 41,442 μm (10,000 mg·L-1). Root number and root dry weight were higher with wounding methods that had larger wounded surface areas. K-IBA altered rooting polarity and stimulated adventitious root formation along the wounded cladode surfaces. Treatments without suberization had a higher percentage of rotted cladodes. This research validates the commercial practice in Mexico of suberizing cladodes early in the propagation cycle. Auxin application could be of commercial benefit for enhanced rooting in the clonal regeneration of new selections for prickly-pear cactus orchards. The wounding methods and auxin treatments utilized make an excellent classroom demonstration for manipulating rooting polarity.

The areas of tropical forests in Indonesia always decrease every year, so that efforts are needed to cultivate plants efficiently for the supply of seedlings. Sungkai (Peronema canescens) has good quality wood that can be used for various purposes, either for construction, furniture, plywood or the leaves can be used for medicine. The purpose of this study was to analyze the growth of stem cuttings of sungkai based on the number of latent buds by calculating the root dry weight, bud dry weight, and total dry weight. This study used a factorial complete randomized design. There were two factors studied, namely the number of buds consisting of 2 levels: 2 buds and 1 bud, and the stem split factor. Each treatment was replicated 3 times and each experiment unit used 5 cuttings. The growth of sungkai cuttings in the treatment of two buds had a total dry weight of 170.04 grams, while the treatment of one bud had a total dry weight of 98.30 grams. The results of this study indicated that the more the number of latent buds, the more root and bud growth of cuttings.Keywords: Coppice; Latent buds; Cuttings; Sungkai

The field experiments with thirty genotypes were conducted during June to October month of kharif, 2018 and kharif, 2019, to assess extent of variability under aerobic condition. The genotypes were sown under dry direct seeded condition using randomized block design (RBD) with three replications. Each genotype was sown in single row of 5 m length with spacing of 20 cm between rows and 15 cm between plants. Data recorded for 22 characters including different morphological and quality traits from 5 randomly selected plants of each replication and mean data used for analysis. ANOVA revealed that the mean sum of squares were highly significant difference for most of the traits. The value of PCV was higher than GCV for all the twenty-two characters. However, maximum GCV and PCV were observed for root dry weight plant-1 (31.44% and 32.17%) followed grain yield plant-1 (29.97% and 31.03%), root volume (28.62% and 29.20%), root fresh weight plant-1 (28.51% and 29.08%), biological yield plant-1 (21.86% 22.50%) and number of grains panicle-1 (20.55% and 21.37%). Rest of the traits showed moderate and low GCV and PCV. High heritability and genetic advance were recorded for the traits viz., leaf length, number of tillers plant-1, number of grains panicle-1, 1000 seed weight, root length, root volume, root fresh weight plant-1, root dry weight plant-1, kernel length-breadth ratio, grain yield plant-1, biological yield plant-1 and harvest index. The information regarding different variability will provide direction to select high yielding genotypes under aerobic condition.

Two experiments were conducted during which juvenile hardwood or softwood stem cuttings of loblolly pine (Pinus taeda L.) were rooted under six mist regimes in a polyethylene-covered greenhouse to investigate the effect of mist level on vapor pressure deficit (VPD) and cutting water potential (Ψcut), and to determine the relationships between these variables and rooting percentage. In addition, net photosynthesis at ambient conditions (Aambient) and stomatal conductance (gs) were measured in stem cuttings during adventitious root formation to determine their relationship to rooting percentage. Hardwood stem cuttings rooted ≥80% when mean daily VPD between 1000 and 1800 hr ranged from 0.60 to 0.85 kPa. Although rooting percentage was related to Ψcut, and Aambient was related to Ψcut, rooting percentage of softwood stem cuttings was not related to Aambient of stem cuttings. Using VPD as a control mechanism for mist application during adventitious rooting of stem cuttings of loblolly pine might increase rooting percentages across a variety of rooting environments.
