“…Interestingly the POX isoform profile (number and relative activity of isoforms) varies throughout the different phases of adventitious rooting (Pastur et al, 2001;Syros et al, 2004) and also differs with rooting ability (Ludwig-Müller, 2003) making it a potential indicator of the underlying processes happening during root formation (Pastur et al, 2001). In olive, Bartolini et al (2008) reported the emergence of a "new polypeptide" that could be related to root formation. However, the results are not clear, the putative protein was not further purified and the conclusions drawn are merely speculative.…”

Olive (Olea europaea) is one of the most important fruit species in the Mediterranean basin, where 95% of the world's olive orchards are planted, and it has become an economically valuable crop worldwide, due to an increasing interest in olive oil for human consumption. New olive orchards are being planted outside the Mediterranean, calling for an effort to identify the genotypes best adapted to the new conditions. However, some olive cultivars remain difficult to propagate, which significantly reduces the capacity to use the full genetic diversity of the species. Improving rooting ability in cuttings from recalcitrant olive cultivars has become a critical topic, which implies fundamental research on the anatomy, physiology, biochemistry and genetics of the adventitious root formation process. Besides, the existence of different rooting behaviors among olive cultivars also makes the species a candidate model plant for these studies. Olive propagation techniques evolved through time from field-or nursery-planted hardwood cuttings, to semi-hardwood cuttings in greenhouses under mist, and, more recently, to in vitro culture techniques. Nevertheless, research about adventitious root formation carried on each propagation method was mostly based on trial and error approaches. Researchers have mainly investigated different factors involved in the process of adventitious rooting by testing their effect in the rooting capacity of different cultivars, leading to a high dispersion and fragmentation of the available information. The goal of this review is to present the most relevant results achieved on adventitious root formation in olive cuttings, aiming to provide an integrated perspective of the current knowledge.

“…Some varieties produce roots from cuttings easily, whereas others are very difficult to root. The Greek 'Kalamata' (Sutter, 2005), the Tunisian 'Chemlali De Sfax' (Fabbri et al, 2004), the Spanish 'Gordal Sevillana' (Gonzalez Padilla et al, 2009), the Portuguese 'Galega vulgar' (Peixe et al, 2007), the Italian 'Leccio del Corno' (Bartolini et al, 2008), and the ornamental 'Swan Hill' (Sutter, 2005) are understood to be difficult-to-root cultivars. In such cultivars, grafting, despite its expense, can be the main method for propagation.…”

The global production of olives (Olea europaea L.) has increased rapidly over the last decade as a result of the expansion of orchards with high tree densities. Most olives are propagated from rooted cuttings. The present study evaluated the propagation rate of rooted cuttings as a function of the nutritional status of the stock trees. Rooting ability was evaluated for cuttings taken from container-grown stock plants exposed to eight concentrations of nitrogen (N) (ranging from 0.4 to 14.1 mm), seven concentrations of phosphorus (P) (ranging from 0.01 to 0.62 mm), and five concentrations of potassium (K) (ranging from 0.25 to 5.33 mm). Increases in N level negatively affected rooting rate and cutting survival. Propagation success was increased threefold as N in irrigation water was reduced from the highest to the lowest treatments. Enhanced root development under low N concentrations resulted in higher root weight compared with the high N concentrations. The high concentration of N fertilization negatively affected the propagation rate but was not reflected in N concentration of diagnostic leaves. There was, however, a significant negative correlation between N in twigs and propagation rate. Regarding response to K concentration, no effect was found on rooting rate or cutting survival. Except for reduced rooting at the lowest concentration, P had a negligible effect on rooting rate. The experimental results indicate the need to avoid overfertilization of olive stock trees with N to promote successful propagation.

“…The most widely used hormone is indole butyric acid (IBA). (Bartolini et al, 2008). Ibrahim et al (1991) The application of 500 or 1000 ppm IBA to Ascolano and Frantoio hardwood cuttings improved olive rooting, and cuttings taken in March had better rooting than those taken in late summer and early autumn.…”

This research was conducted in Bakrajo Nursery Station/ Sulaimani/ Kurdistan Region-Iraq through the growing season of 2016. We used Shami and Qaisi olive CVs. which were uniform to test the effects of concentrations of IBA hormone (0, 1000, 2000, and 3000 ppm) and during three dates (15/3, 1/4, and 15/4) on the vegetative growth of semi-hardwood olive cuttings CVs. 'Shami' and 'Qaisi.' The following is a brief of the results: IBA hormone therapy had a major impact on most vegetative characteristics. On the majority of the vegetative development, Shami cv. significantly outperformed Qaisi cv
