“…These results accord with findings from other woody plants including Castanea sativa Mill., Syringa vulgaris L., Prunus persica L., P. cerasus L. × P. canescens Bois and Eucalyptus globulus Labill. [48][49][50]. They are also similar to recent results from the 10-node seedlings of C. torelliana × C. citriodora, where varying rooting capacity among the nodes was poorly related to differences in IAA or ABA concentrations [20].…”

Repeated pruning of stock plants is a common approach to delaying maturation and maintaining the propagation ability of cuttings, but little is known about the hormonal or anatomical basis for this phenomenon. We tested the effect of two different stock-plant pruning heights (15 cm and 30 cm) on shoot production, rooting capacity and rooted cutting vigour of six clones of the eucalypt Corymbia torelliana × C. citriodora. We determined whether differences in rooting potential were related to indole-3-acetic (IAA) and abscisic acid (ABA) concentrations, or the degree of lignification or sclerification, of the cuttings. Maintaining stock plants at 15 cm height sometimes reduced the production of stem cuttings. However, it often increased the ensuing percentage of cuttings that formed roots, with mean rooting across all clones increasing from 30%-53%. Therefore, the number of rooted cuttings produced by short stock plants was similar to, or higher than, the number produced by tall stock plants. Cuttings from shorter stock plants had faster root elongation and occasionally greater root dry mass, shoot dry mass or shoot height than cuttings from tall stock plants. These differences in rooting potential were generally not related to differences in IAA or ABA concentrations of the cuttings or to differences in their stem anatomy. Pruning at the lower height was more effective in maintaining clonal juvenility, supporting previous OPEN ACCESSForests 2015, 6 3764 findings that stock plant maturation is a limiting factor in clonal propagation of Corymbia torelliana × C. citriodora.

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.

“…However, a pattern of auxin synthesis in apices and young leaves followed by transport towards the shoot base could explain why IAA concentrations in C. torelliana 9 C. citriodora seedlings differed only between nodes 7/8 and 9/10. Endogenous auxin levels are a critical factor in the successful rooting process of many plants (Osterc et al 2009;Osterc and Stampar 2011;Costa et al 2013) but the lack of association between IAA concentrations and rooting capacity in C. torelliana 9 C. citriodora cuttings accords with results from Castanea sativa, Syringa vulgaris, Prunus persica, P. cerasus 9 P. canescens and Eucalyptus globulus (Ford et al 2002;Tsipouridis et al 2006;Negishi et al 2014). Rooting capacity of P. persica cuttings is also not correlated with ABA concentration (Tsipouridis et al 2006).…”

Topophysis in Corymbia torelliana × C. citriodora seedlings: adventitious rooting capacity, stem anatomy, and auxin and abscisic acid concentrations

Low amenability of the eucalypt, Corymbia torelliana 9 C. citriodora, to vegetative propagation has limited its establishment in plantations. This study determined whether rooting capacity and cutting vigour varied along the central shoot of Corymbia seedlings, and whether these differences are related to stem development and hormone concentrations. Dual-node cuttings were harvested from five positions (nodes 1/2, 3/4, 5/6, 7/8 and 9/10) along the seedling shoot (S1), and cuttings were treated with one of four levels of indole-3-butyric acid (IBA). Root formation, root and shoot growth, stem anatomy, and the concentrations of indole-3-acetic (IAA) and abscisic acid (ABA) were assessed at each shoot position. The central node of the rooted cuttings was harvested for fresh cuttings to observe whether maturation emerged in ramets (S2) from the different ortet positions. Rooting and vigour were highest from the most-apical seedling nodes (7/8 and 9/10 in S1), which had less lignification and sclerenchyma development than morebasal nodes (1/2, 3/4 and 5/6). IAA and ABA concentrations differed little between the seedling nodes. In contrast, cuttings from the ramets (in S2) had similar rooting, vigour, lignification and sclerification to each other, but there were large differences in IAA and ABA concentrations depending on their previous point-of-origin in the seedling. High doses of IBA reduced rooting. Rooting and vigour were related to lignification and sclerenchyma development rather than IAA or ABA concentrations. Mass vegetative propagation of C. torelliana 9 C. citriodora is achievable because mean rooting percentages in S1 and S2 were 61 and 68 %, respectively, using cuttings from small seedling ortets and their ramets.
