Cutting Type and Auxin Treatment Affect Rooting of Cupressus cashmeriana

Cupressus cashmeriana is an ornamental evergreen conifer with little published information on vegetative propagation. Two experiments were conducted to determine the effects of cutting type and auxin concentration and form on adventitious rooting. Experiment 1 evaluated three cutting treatments (softwood, hardwood, and mallet) and four auxin treatments consisting of 0, 2500, 5000, and 10000 ppm potassium salt of indole-3-butyric acid (K-IBA). Experiment 2 evaluated the same cutting types as experiment 1 and auxin treatments consisted of 5000 ppm K-IBA, 5000 ppm naphthalene acetic acid (NAA), 2500 ppm K-IBA in combination with 2500 ppm NAA and zero auxin applied. In both experiments, rooting of softwood and hardwood cuttings was significantly higher than mallet cuttings. Treatment of cuttings with different rates and types of auxin lead to inconclusive results, which indicate auxin may not be beneficial for rooting of C. cashmeriana. This research suggests that the age of plant material is one of the most significant factors for successful rooting C. cashmeriana.

Hormonal Treatments

The effect of hormone on the rooting of stem-cuttings and marcotting of akee apple was studied using a combination between Indole -3- Butyric Acid (IBA) and 1- Naphthalene Acetic Acid (NAA). Stem-cuttings from mature akee trees from Challenge, Jalala and Ganmo in Ilorin, were treated with different dilutions of the liquid hormone in the combination of 1.0% Indole-3- butyric acid + 0.5% 1-Naphthaleneacetic acid before propagating them in a non-mist propagator. Marcotting was also carried-out on trees, using the hormonal combination of different dilutions. Observations and the results obtained revealed that the hormonal combination had significant effect on the rooting of stem-cuttings and marcotting. Both marcotting and stem cuttings did not produce at the end of the experiment roots in the absence of the hormonal treatment; a particular aspect was marcotting that initials produced roots. On the other hand, both marcotting and stem cuttings produced roots with the hormonal treatments; more roots were produced using the combination of 2,000 ppm of IBA and 1,000 ppm of NAA, compared with lower concentrations of the hormone mixtures. After callus formation, 2,000 ppm of IBA and 1,000 ppm of NAA combination gave the best results within stem-cuttings. Based on the results obtained, it was concluded that the combination of IBA and NAA in appropriate concentration promoted rooting in Akee apple and therefore are highly valuable for the vegetative propagation of this species through stem cutting and marcotting.

Abstract Amur maple (Acer ginnala Maxim.) is a widely planted small tree with attractive red fall foliage. In many states, it is classified as a noxious weed and regulations restrict propagation and sale, limiting customer choice. Stem cuttings are commonly used as a means of asexual propagation of Amur maple, with softwood cuttings being the easiest to root. Here we report adventitious rooting efficiency of seedless Amur maple selections using four indole-3-butyric acid (IBA; 500, 1,500, 5,000, 10,000 ppm) and four naphthalene acetic acid (NAA; 100, 500, 1,500, 5,000 ppm) treatments and a no hormone control. Overall, cuttings treated with 5,000 or 10,000 ppm IBA and 5,000 ppm NAA resulted in the highest percent rooting (PR), mean number of roots (MNR), and mean length of the longest root (MRL) across all seedless selections. Seedless selections SW-30-14 and SW-30-130 had the highest PR, 66% and 67%, respectively, and will perform well in commercial propagation. This level of rooting was greater than that of the cultivar ‘Bailey Compact' that had 46% PR, and the seedless selection SW-30-159 that had the lowest PR (10.3%), MNR (0.3), and MRL (0.2 in) averaged across all treatments. Cuttings from 4 of the 5 seedless selections treated with 1,500 ppm NAA had the greatest PR, whereas ‘Bailey Compact' and SW-30-159 had the greatest PR with 5,000 ppm NAA. Results indicate that rooting efficiency was impacted by mutagenesis in some selections, which may require optimization of propagation methods for those selections. Index words: adventitious rooting, auxin, vegetative propagation, sterile, non-native invasive. Species used in this study: Amur maple (Acer ginnala Maxim.). Chemicals used in this study: indole-3-butyric acid (IBA; 500, 1,500, 5,000, 10,000 ppm) and naphthalene acetic acid (NAA; 100 500, 1,500 5,000 ppm).

In this study, Dianthus caryophyllus L. was used as the experimental plant to investigate the effects of rooting substrate and exogenous auxin concentration on the adventitious rooting of the stem cuttings. Our results showed that the formulated substrates with different physicochemical properties significantly affected the root formation. The substrate with a ratio of cocopeat to perlite at 1:1 (v:v) resulted in the optimum rooting of D. caryophyllus cuttings. Different Indole-3-butyric acid (IBA) and 1-naphthalene acetic acid (NAA) concentrations affected the rooting percentage and seedling rate of D. caryophyllus. Application of NAA at 1000 mg·kg−1 with IBA at 100 mg·kg−1 resulted in the greatest rooting percentage and improved breeding speed. The rooting percentage and seedling rate did not increase with the increase in auxin concentration. Based on these results, we concluded that an appropriate rooting substrate is required to fulfill proper rooting of D. caryohhyllus cuttings, whereas an exogenous application of IBA and NAA at 1000 mg·kg−1 and 100 mg·kg−1 promoted the rooting and a higher auxin concertation inhibited rooting.

Native Piper species present significant repellent, antimicrobial, inseticidal, anti-tumor and anti-protozoal biological activities. Studies on new species can discover unpublished potentialities and vegetative propagation for the development of cultivation protocols and reduce the natural extraction. The objective of this study was to evaluate the rooting of P. arboreum, P. cernuum and P. diospyrifolium stem cuttings with different treatments containing doses of indole butyric acid (0, 500; 1,000; 1,500; 2,000 and 3,000 mg L-1). Branches were collected in the “Bom Jesus Biological Reserve”, Parana state, Brazil. The cuttings, with a length of 12 cm and average diameter of 6 mm, were placed in 53 cm3 plastic tubes with the commercial substrate Tropstrato HP® and intermittent misting. After 90 days, the survival, mortality, cuttings with new shoots, number and length of the three main roots were evaluated. The percentages of rooting reached an average of 67.5% for P. arboreum, 51.6% for P. cernuum and 50.4% for P. diospyrifolium. A positive effect in the treatments containing the plant regulator was observed for rooting development, percentage of cuttings with shoots and number of roots per propagule, but there were variations in the responses of each species. Leaf retention was an important factor for the adventitious rooting formation in all evaluated species.

Couroupita Guianensis

The present study explores the potential of exogenous auxins in the development of adventitious shoots and roots from shoot cuttings of Couroupita guianensis (Nagalingam), a threatened tree. Experiments were conducted to assess the effect of various concentrations of auxins on shoot and root morphological traits of stem cuttings in the greenhouse. Amongst the auxins tested, significant effects on number of shoot buds’ induction and their growth were observed with α-Naphthalene Acetic Acid (NAA) treated nodal cuttings. Cent percentage of the stem cuttings of C. guianensis were rooted and shoots were induced when pretreated with 400 mg L−1 NAA for 5 min. Maximum 79% of stem cuttings responded to pretreatment of 300 mg L−1 indole-3-butyric acid (IBA) for 5 min, and 75% of stem cuttings induced shoots with 400 mg L−1 indole-3-acetic acid (IAA). Presence of at least 5 nodes on stem cuttings was found to be prerequisite for root and shoot induction. About 92% of plants were survived under natural soil conditions raised from the stem cuttings. This is the first report of vegetative propagation of C. guianensis through stem cuttings which could be used for conservation strategy and sustainable utilization of this threatened medicinal tree.

Time Periods

This experiment has been carried out in order to determine the rooting ability of hardwood cuttings of the blueberry cultivar ‘Bluecrop’ collected during the deep dormant winter period in the last part of January. In order to induce the adventitious roots formation, the cuttings were stimulated using Indol Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA) in various concentrations (1500, 3000, 4500 ppm), whilst one row in each box remained intact (control). The collection of cuttings off the mother plant at the beginning of January enable the nutrients and other matter that help the process of rooting not to move from the base of cutting towards the top and consequently they remain at the base of cutting which results with quite a high rooting percentage (up to 72.5%) compared to the cuttings collected in February with rooting percentage of 67.5% and in March (52%). In both types of substrate, turf and turf-perlite 2:1 and in different time periods when cuttings have been collected, IBA proved to be better in inducing adventitious roots compared to NAA.

Auxin Concentration

Medicago truncatula (Jemalong 2HA) can be regenerated by somatic embryogenesis utilising 1-naphthalene acetic acid (NAA) and 6-benzylaminopurine (BAP). There is a requirement for both NAA and BAP for callus induction and embryo formation. There is no requirement for a drop in auxin concentration to induce embryos. Abscisic acid (ABA) when present with NAA and BAP during embryo formation at a concentration of 1 µM, increases the number of embryos per callus. The ABA treatment stimulates embryo numbers in both light and darkness. The conversion efficiency of embryo to plant is unchanged irrespective of the presence of ABA during embryo formation, indicating that ABA does not improve the regeneration of the embryos once formed. Importantly, the presence of light in the embryo formation period causes a marked inhibition of embryo conversion.
