“…Subterminal cuttings also possess a good potential for successful propagation of various species, as suggested by several researchers [34,35]. In Acer truncatum, Brock and Griffin [36] did not find a significant influence of cutting position for all rooting parameters tested in the presence of auxin. Furthermore, Tilahun et al [37], working on Araucaria heterophylla, reported that among three cutting positions on the shoot (tip, middle and bottom), the shoot tip material showed significantly higher rooting ability than middle and bottom parts.…”

The market demand for interesting varieties and cultivars of Ilex aquifolium necessitates the exploration and sustainable exploitation of plant individuals thriving in nature without human care. In this work, an effort was made to develop a simple and reliable protocol for vegetative propagation of I. aquifolium plants, with desirable-for-market characteristics, grown in a mountain area of Halkidiki, Greece, and at the same time to proceed with their genetic identification using molecular markers. From these plants, new plants were vegetatively produced which afterward were used as stock plants for providing the needed shoot cuttings for the experiments of rooting and leaves for their genetic analysis. Factors studied in formulating a propagation protocol included the season of cutting collection and the application of 0.2% 1-naphthaleneacetic acid (NAA), as well as the type of shoot cuttings (terminal, subterminal) and the application of auxin. It was found that application of NAA was crucial for rooting response and number of roots formed, whereas the season effect was not significant on rooting. Terminal cuttings treated with 0.2% NAA exhibited the highest rooting percentage (100%) and formed abundant roots (25.7) compared to subterminal ones. All rooted cuttings, after being potted and transferred to acclimatization greenhouse, were successfully hardened. In the spring of the next year, the produced plants blossomed abundantly and formed fruits (bright red berries) presenting their characteristic ornamental appearance that was maintained until Christmas. For the identification procedure, the genotypic profile of the stock plants was also investigated by inter-simple sequence repeat (ISSR) genetic analysis, revealing that they were genetically the same both among themselves and when compared with a certified I. aquifolium ‘Agrifoglio Commune’ individual, but they differed genetically from I. aquifolium ‘Argentea Marginata’ and I. aquifolium ‘Hellas’.

Adventitious root formation is the key to successful propagation of olives through cuttings. Etiolation, as an eco-friendly practice, can modulate the plant’s endogenous phytohormone, which plays an important role in stimulation of rooting of cuttings. Therefore, this study was aimed to investigate the effect of etiolation on the rooting behavior of both ‘Manzanillo’ and ‘Picual’ olive cuttings (terminal and sub-terminal) treated with IBA (0, 4000 ppm). The results indicated that sub-terminal cuttings in both cultivars were more effective in olive propagation than terminal cuttings as they recorded increased leaves number, C/N ratio, total carbohydrates, total indoles, IAA, IAA/GA ratio, and total phenols. Etiolation of both olive cultivars for both terminal and sub-terminal cuttings significantly decreased rooting percent, roots number, IAA, and IAA/GA ratio; while, it increased GA and GA/IAA. Moreover, etiolation decreased total sugars, IAA, IAA/GA ratio, and indole/phenol ratio in both sub-terminal cuttings. Terminal ‘Manzanillo’ cuttings achieved a higher rooting percent than terminal ‘Picual’ cuttings by 5.83% and 202.2% as mean of both seasons for untreated and IBA-treated cuttings, which was accompanied by significant increase in vascular bundle%, total phenol, phenol/indole ratio, IAA, and IAA/GA ratio by 21.48%, 49.2%, 44.72%, 12.9%, and 22.9%, respectively. Also, terminal ‘Manzanillo’ cuttings recorded lower GA by 7.98% and GA/IAA ratio by 18.21% and pith by 6.13% than terminal ‘Picual’ cuttings. This study proved that olive plants need exposure to full sunlight to propagate easily by cuttings since etiolation had negative effects on IBA-treated cuttings.
