“…Stereospermum suaveolens cuttings produced the longest root with IBA (Baul et al, 2008). Similar results were obtained for the cuttings of Shorea leprosula (Aminah et al, 1995), Ulmus villosa (Bhardwaj and Mishra, 2005), Lippia javanica (Soundy et al, 2008), Buchholzia coriacea (Akinyele, 2010), Ficus hawaii (Hassanein, 2013), Massularia acuminate (Usman and Akinyele, 2015), Cyclopia subternata (Mabizela et al, 2016) and Toona ciliata (Thakur et al, 2018).…”

The common method of propagation is through seeds but seed germination in Zanthoxylum armatum is very low due to the presence of hard seed coat, which might be a great hurdle for large scale production of plantlets. So an attempt was made in this study to see the effect of different growth hormones, their concentrations and different rooting media on the rooting and sprouting of Z. armatum. The stem cuttings of Z. armatum were treated with two types of auxins namely Indole-3-Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA) at different concentrations (2000 ppm, 3000 ppm and 5000 ppm), while the untreated cuttings were used as control. The cuttings were planted in three different rooting media: sand, neopeat and mix (containing a mixture of sand, soil and vermin-compost). The completely randomized design was used for the experiment. The total number of stem cuttings of Z. armatum used in the experiment was 1080 for 18 treatments in three replicates (20 cuttings per treatment x 18 treatments x 3 replicates). The experiment was set up in controlled greenhouse conditions at Dabur Nepal Private Limited Nursery, Banepa, Kavre District. The parameters evaluated were root length, shoot length and number of roots per cutting. The collected data were analyzed statistically using R-program with Agricola. Least significant difference (LSD) and Duncan multiple Range Test (DMRT), as mean separation technique was applied to identify the most efficient treatment in the rooting and shooting behavior of Z. armatum (Gomez and Gomez, 1984). Hormone concentration and growth media significantly affected the rooting and shooting ability of Z. armatum stem cuttings. IBA was found to be more effective than NAA. Neopeat medium was better than sand and mix media. The highest number of roots (6.5) and root length (11.6 cm) were recorded under IBA 5000 ppm in neopeat medium.

“…Milled pine bark and 0.8% IBA gave the highest incidence of root and shoot development (Akwatulira et al 2011). A similar study on the woody perennial honeybush (Cyclopia subternata Vogel) developed specific recommendations for commercial substrates and rooting gels, and determined the best time of year to take and establish rooted cuttings even in a mild climate (Mabizela, Slabbert, and Bester 2017). In addition to cutting survival times being influenced by the season, auxin requirements may change seasonally.…”

Limited rooting and acclimatization success when micropropagating certain hardwood tree species may hinder conservation efforts of certain threatened and endangered species. Restoration efforts for such trees, such as the American chestnut [Castanea dentata (Marsh.) Borkh.], require a massive number of plantlets to be produced by micropropagation for testing, initial distribution, and orchard establishment. Therefore, increasing the number and quality of lab-produced plantlets is a key research focus. After previously determining that an ex vitro rooting system produced significantly more robust plantlets, we examined extending the time in elongation medium, rooting substrates, exogenous auxin applications, root-promoting substrate soaks, submerging the cut site, and light intensity. The most effective methods included seven weeks in elongation medium, using Jiffy peat pellets soaked in water as the rooting substrate, cutting off callus while submerged, then dipping in 0.31% IBA rooting gel, and placing plantlets in low light of 60 μmol·m-2·s-1 after rooting. By increasing the number of roots and improving acclimatization success, we can ensure that many more blight-tolerant American chestnuts will be available for field studies and eventual public distribution. Demonstrating the ecological safety and blight survival of these trees will help restore this foundational tree species and assist future restoration efforts for other threatened species. Index words: Rooting, ex vitro, American chestnut, Castanea dentata, IBA, substrate. Species used in this study: American chestnut, [Castanea dentata (Marsh.) Borkh.]. Chemicals used in this study: IBA (indole-3-butyric acid).

“…Plant root formation is affected by the physical and chemical properties (bulk density, porosity, water-/air-holding capacity, pH, EC) of the rooting substrates (Altman and Freudenberg, 1983). The ideal substrate is able to provide a proper water and oxygen balance, thus promoting oxygen availability, transpiration, nutrient uptake, growth, and aeration during root initiation of stem cuttings (Mabizela et al, 2017). The water content is a key factor in the survival of cuttings, especially during the initial rooting phase when the transpiration and physiological activities rely on the stem insertion in the substrate (Grange and Loach, 1983).…”

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.
