“…The use of plant growth regulators, indolebutyric acid (IBA) in this case, is recommended to stimulate and accelerate the adventitious roots formation process (Singh et al 2004, Guo et al 2009), increase the rooting index and increase velocity of formation, quality and uniformity of the root system (Hartmann et al 2011). Similar results were described by Mayer et al (2001), who worked with Chinese plum (Prunus mume Sieb.…”

SUMMARYEpicormic shoots were induced in stumps and detached branches of adult Paulownia fortunei var. mikado plants to evaluate rooting potential. Stem cuttings obtained from shoots of stump were prepared with 12 cm in length and two leaves reduced to 78.5 cm² (10 cm diameter). Cuttings from shoots of branches were prepared with 8-10 cm in length, and two leaves reduced to 50 % of the original size. Anatomical analysis was performed to evaluate possible barriers to rhizogenesis. After disinfestation, indolebutyric acid (IBA) was applied (0, 500, 1,000, 1,500 and 2,000 mg L -1 ). Installation was made in plastic pots with a volume of 170 cm³ and 53 cm³, respectively for each type of cuttings, with fine vermiculite and carbonized rice hulls (1:1 v/v) as substrate. After 60 days in a greenhouse, cuttings from epicormic shoots of branches presented rooting (58.12 %) and the average length of the three longest roots/ cutting (4.76 cm) was higher than in cuttings from stumps. The highest number of roots/cutting (7.66) and percentage of cuttings with callus (27.50) was observed in cuttings from stumps. There were no anatomical barriers observed harming the roots formation in the two types of cuttings. The use of indolebutyric acid is not required to induce rooting.

“…The superiority of IBA compared to NAA for AR of the cuttings has also been revealed in other plant species such as Paeonia 'Yang Fei Chu Yu' (Guo et al, 2009) and Macleania rupestris (Veloza et al, 2014) because of its several advantages such as greater stability to light than others (Kurepin et al, 2011;Pacurar et al, 2014), localized action, persistence and low toxicity (Fachinello et al, 1995 Expt. II was designed on 09 June to explore the effects of three CPAs including control and four substrates (perlite, peat, peat: sand, cocopeat:sand) on rooting of E. manipuliflora cuttings.…”

Abstract. The use of Erica manipuliflora, a decorative native ornamental species, is limited in landscaping due to insufficient plantlet production in nurseries. The aim of study was to determine the most effective and practical adventitious rooting (AR) protocol for successful vegetative production of E. manipuliflora. Two experiments (Expt.) were established in November and June to reveal the effects of different substances [perlit and perlit:sphagnum peat (1:1 v/v) in Expt.I and peat, peat:sand (1:1), cocopeat:sand (5:1) and perlite in Expt.II] and exogenous auxins including liquid (in Expt.I) and powdered (in Expt.II) formulations of IBA, NAA or combination of both. The results indicated E. manipuliflora cuttings taken in June and cultured in cocopeat:sand (5:1) mixture without any auxin treatment presented the highest survival (84%) and rooting (76%) performance. In addition, exogenous auxin usage is not essential for AR of E. manipuliflora cuttings. It can be used for the cuttings inserted in cocopeat-free media. But it exhibited reducing effect on rooting in cocopeat-based medium. The use of mycorrhizal inoculation and also minicuttings in eco friendly cocopeat-based media in future studies might increase the efficiency of E. manipuliflora AR protocol.

“…However, the changes in the levels of endogenous hormones were very complex, and many contrasting results were reported [49,50,42], which was most likely due to plant species, duration investigated, position of plants, environment factors, etc. Furthermore, it can be conjecturable that exogenously applied auxin possibly alter the concentrations of endogenous hormones, thus the original balance among endogenous hormones is replaced by the new balance beneficial to root formation [51].…”

In the present study, an attempt was made to induce rooting from single-node cuttings of hybrid aspen (Populus tremula L. ×P. tremuloides Michx.) with different concentrations of IAA, IBA and NAA during rooting. Among the three auxins used, NAA showed more effective induction on rooting as compared to IAA and IBA at the whole level. Thereafter, NAA was used further in experiments for anatomical and biochemical investigation. The results showed that it took 12 days from the differentiation of primordium to the appearance of young adventitious roots with NAA application. It was found that endogenous IAA, ZR and GA3 levels increased, but ABA decreased in cuttings with 0.54 mM NAA treatment. In contrast to the endogenous IAA level, NAA had negative effect on IAA-oxidase (IAAO) activity. Similarly, the decreased peroxidase (POD) activity, consistent with down-regulation of expressed levels of POD1 and POD2, was observed in NAAtreated cuttings. Whereas, NAA resulted in a higher activity in polyphenol oxidase (PPO) compared to the control cuttings. Collectively, the study highlighted that 0.54 mM NAA is efficient on rooting in hybrid aspen, and its effect on metabolic changes during rooting is discussed, which provide valuable information for propagating hybrid aspen.
