“…This can be attributed to the presence of a growth regulator IAA, minerals and vitamins in these plant extracts. Comparable findings to those of this study demonstrated the function of licorice extract in elevating indices of root growth for Gardenia plants [8], hardwood cuttings of olive (Olea europaea L.) [24], and Coratina olive cuttings [28].…”

The experiment ran from the middle of February until the start of November 2023 under the plant canopy of the Department of Horticulture and Landscape, College of Agriculture, University of Kerbala. The study employed a Randomized Complete Block Design (R.C.B.D.) as a factorial experiment, with two pomegranate varieties (Yamani and Bashkan) as the first factor and various combinations of natural and chemical rootings as the second factor. These included extracts of moringa leaves (M0, M1) and licorice roots (L0, L1) at concentrations of 0 and 15 g L-1 each, as well as indole butyric acid at a concentration of 0 and 10 mg L-1 (B0, B1). The majority of the root features of the resultant seedlings demonstrated that, overall, the Bashkan variety outperformed the Yamani variety; however, this superiority varied when combined with other rooting combinations. Between the rooting stimulant combinations utilized in the study, the cuttings' dipping results differed. When it came to the quantity, size, and fresh and dry weight of the root system, indole butyric acid in combination with B1M0L0 performed better. It resulted in 250.000 root seedlings-1, 2.270 cm3, 20,680 g, and 6,650 g, respectively. In contrast, the B0M0L1 licorice root treatment demonstrated superior root length, reaching 38,100 cm. Both the percentage of rooting and the average root diameter were the largest in the combination including both extracts, B0M1L1, reaching 5.170% and 1.603 mm, respectively. Given that natural extracts have outperformed chemical radicals in the majority of the rooting qualities under study—such as licorice root extract and moringa leaf extract—it is possible to conclude from the aforementioned results on their suitability for usage as an alternative.

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.
