“…Itrana produced significantly the shortest roots which averaged 3.62 and 3.34 cm in the two seasons. These results are in parallel with previous findings of Kilany (1991), Hegazy (2003) and Turkoglu and Durmus (2005) who found that the average root length per rooted cutting differed with different olive cultivars.…”

This study was conducted in North Sinai Research Station at El-Sheikh Zuwayid, Desert Research Center (D.R.C.) during the 2006 and 2007 seasons. It aimed at evaluating the effect of different propagation techniques and collection dates of cuttings on rooting ability of five recently introduced olive cultivars.Leafy subterminal cuttings of olive cultivars Chiperssino, Tanche, Jabaa, Conservollia and Itrana were prepared during March, June, September and December, treated with IBA at 4000 ppm and rooted using intermittent mist, vapor pressure deficit (V.P.D.) and wooden boxes propagation techniques. A wide variation in rooting ability of the studied cultivars was found. Cuttings of olive cv. Cheperssino had a significantly superior rooting percentage, whereas, cuttings of olive cv. Itrana gave the lowest significant percentage. Moreover, cuttings sown in wooden boxes exhibited the highest significant rooting percentage in comparison to V.P.D and mist propagation techniques. In addition, June collection date showed the highest significant rooting percentage, number of roots and root length under V.P.D. and mist propagation techniques. Meanwhile, the wooden boxes propagation technique significantly resulted in the highest rooting percentage during March collection date.

“…gave the lowest significant number of roots per rooted cutting as it averaged 2.37 and 1.92 roots/cutting in the two seasons. The correlation between rooting ability and average number of roots for different olive cultivars was reported by several workers (Sghir et al, 2003 andTurkoglu andDurmus, 2005).…”

“…The olive cuttings are usually treated with Indole Butyric Acid (IBA) to promote rooting and the concentrations of plant growth regulator treated also affect the rooting abilities (Serrano et al, 2002). However, for a hard-to-root cultivar (HR) Domat, which bears large fruits, IBA is insufficient for inducing rooting (Cetintas Gerakakis and Ozkaya, 2005;Turkoglu and Durmus, 2005).…”

Strigolactones (SLs) are synthesized in roots and control plant development. As phytohormones, SLs regulate plant architecture, including roots. Recently, the inhibiting effects of SLs on the adventitious rooting have been identified. Olive (Olea europaea L.) is consumed for oil and table in Mediterranean countries and is an economically important crop. Turkey is one of the countries with the highest olive production. Olive is mostly propagated asexually via cuttings, however the rooting capacities of some agriculturally important olive cultivars is very low. Indole Butyric Acid (IBA) is commonly used to promote rooting of the olive cuttings, however it can be inadequate. Ayvalık is an easy-to-root cultivar and one of the most common cultivars grown for oil production and Domat is a hard-to-root cultivar which IBA is insufficient for inducing rooting. In our study, the effects of synthetic SLs rac-GR24 and SLs biosynthesis inhibitor TIS108 on the rooting ability of olive cuttings were investigated. As a result, the adventitious rooting ability was increased when a hard to root cultivar was treated with TIS108, indicating a promising future for olive cutting rooting. Therefore, our study will provide potentially new tools for propagation strategies using SLs in fruit trees.

“…multiplication (Dvin et al, 2011;Hartmann et al, 2002). Rooting ability of olive cuttings is subjective to several factors concerning rooting media (Awan et al, 2003;Isfendiyaroglu et al, 2009), cuttings types, olive varieties (Loreti and Hartmann, 1964;Turkoglu and Durmus, 2005), source of cutting material (Ahmed et al, 2002;Sebastiani and Tognetti, 2004) and the growth hormone with its concentration (Asl-Moshtaghi and Shahsavar, 2011;Hartmann et al, 2002). Light intensity is an important phenomenon for the successful propagation of rooted cuttings.…”

O live (Olea europaea L.) is long-lived and evergreen plant that belongs to the Oleaceae family, that has been originated in the Mediterranean region (Isfendiyaroglu, et al., 2009). The Oleaceae family contains about 26 genera and 700 species. Spain, Italy, Turkey, and Greece are the largest producers of olive oil followed by Portugal, Algeria, Tunisia, and Morocco. In addition to the Mediterranean region, olives are also grown in the United States, the Middle East, Australia and Argentina (Seyhan and Gezerel, 2005). The demand for olive sampling has increased in Asian markets due to its vast prospective and climatic adaptability in the region (Mehri, 2009). There are several asexual propagation methods like budding, grafting cuttings and air layering but propagation through cuttings is considered the easiest and economical method for olive Abstract | Olive cultivation in Pakistan is being commercialized at a fast pace in selected agro-climatic regions. The demand for local plants is increasing and no scientific study has been previously carried out to standardize propagation technology concerning optimization of light intensity under greenhouse conditions. The current study was conducted at Izhar farms (Pvt.) Ltd. under the collaboration with Barani Agricultural Research Institute (BARI) Chakwal to find out the appropriate light intensity for successful olive propagation under greenhouse conditions. The data regarding days to root initiation, number of roots, root length, days to shifting, rooted cutting percentage and callus percentage were collected under four different treatments. Cutting under the only green net (5944 lux), white net (11428 lux) only upper side white net (8484 lux) and both green and white net (5538). The results were found significant regarding the interaction between varieties and treatments; however, non-significant variation in varieties was found regarding the number of roots, days to root, and days to shift. The important observations regarding the results were found that minimum light intensity delayed the rooting percentage and increased the callus formation while higher light intensity increased mortality with increased root length in both varieties with moderate callus formation. Up to three weeks, there was no root development under all treatments. The cuttings under light intensity (8484 lux) produced more numbers of roots, with early initiation in both varieties. Variation in varietal performance was observed under different treatments however 8000 lux light gave better results in all the parameters.
