“…The greater length of roots may be as a result of more available carbohydrate reserves, nutrients and optimum hormonal supply. These results are also in line with Awan et al, (2012) who found maximum root length in 20 cm length of olive cv. Azarbaizan.…”

“…In hardwood cuttings, the increase in cutting size negatively affects rooting being accompanied by a decrease in the number of roots per cutting (Awan et al, 2012). A reverse trend is observed in semi-hardwood cuttings and microcuttings Haq et al, 2009).…”

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.

“…Overall, the different concentrations and combinations of growth regulators showed better results compared with the control. IBA 1600 ppm was the best concentration of growth regulators followed by NAA 7000 ppm in terms of all the parameters tested [30][31][32][33].…”

Clonal propagation is a process of asexually reproducing plants by multiplication of one copy to produce several copies that are genetically identical. One of the best methods of clonal propagation is using the cuttings. There are many plants that can be propagated through cuttings and one of them is guava. Guava is popular in Pakistan. To ensure that a guava tree will produce fruits that belong to its original cultivar, this study was conducted. Softwood cuttings of guava were treated with IBA (1600 ppm and 2000 ppm), NAA (7000 ppm and 10,000 ppm) and IBA+NAA (1600+7000 ppm and 2000+10,000 ppm). There were five media used (Soil, Peatmoss+Soil, Sand+Soil, Baggasse+Soil and Soil+Peatmoss+Sand+Bagasse. The experiment was laid out using Completely Randomized Block Design (CRBD) with two-factor factorial arrangement. A total of 105 cuttings were used, each with 12 cm length and with 2-4 nodes. Media samples were collected and physio-chemically analyzed at the Soil and Water Testing Laboratory in Layyah, Pakistan to assess the properties and fertility status. Guava cuttings with 1600 ppm IBA showed the best results in terms of the number of roots, root length and days to sprout, followed by 7000 ppm NAA in Peat moss+soil and soil+peat mass+sand+bagasse. For the combination of growth regulators, the best results were observed in IBA 1600 ppm + NAA 7000 ppm. Poorest result in all parameters (days to sprout, number of roots, and root length) was recorded in control. The 1600 ppm IBA with 10 second dipping time for softwood cuttings of guava yielded best results in peatmoss+soil media for all the parameters tested. Hence, this study concluded that treatment with auxin (such as IBA) can yield best results and can help to solve the problem in propagating guava using cuttings.
