“…xylogenesis. Xylogenesis consists of the ectopic formation of xylary elements and it is induced by auxin (Ricci et al , 2016, and references therein) and by ethylene (Pesquet and Tuominen 2011), and occurs as an alternative or competitive program to AR formation in cuttings of numerous species (Faivre-Rampant et al , 2003; Ricci et al , 2016). Moreover, in etiolated Arabidopsis seedlings, the same auxin-reactivated pericycle cells can produce either ARs or xylary elements, with xylogenesis needing lower levels of auxin to be initiated (Della Rovere et al , 2015).…”

“…can be rooted effectively with the application of auxins (Table 1). Auxins are well known to play a significant role in stimulating AR from stem cuttings of tree species [22][23][24][25]. In addition to enhancing the rate of AR development, auxin application has been found to increase the number of roots initiated per rooted cutting in a variety of species [26,27].…”

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 Indole-3-acetic acid (IAA), Indole-3-Butytric acid (IBA) and 1-Naphthylacetic acid (NAA). Among the three auxins used, 0.54 mM NAA showed more effective induction on rooting as compared to IAA and IBA at the whole level. Thereafter, 0.54 mM NAA was used further for the anatomical and biochemical investigation. The results showed that it took 12 days from the differentiation of primordium to the appearance of young adventitious roots under NAA application. It was found that endogenous IAA, Zeatin riboside (ZR) and Gibberellic Acid (GA3) levels increased, but Abscisic acid (ABA) decreased in cuttings with NAA treatment. In contrast to the endogenous IAA level, NAA resulted in a decrease in IAA-oxidase (IAAO) activity. Similarly, the decreased peroxidase (POD) activity, consistent with down-regulation of expressed levels of POD1 and POD2, was observed in NAA-treated cuttings. Moreover, NAA resulted in a higher activity in polyphenol oxidase (PPO) compared with 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 was discussed, which can provide valuable information for propagating hybrid aspen.

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.
