“…In support of our findings, a 70% rooting ratio was obtained from the MS medium containing 1 mg L -1 IBA (Grigoriadou & Leventakis 2000). However, we have observed darkening on the explant's base and an unhealthy shoot development when shoots were rooted without AC (Figure 2b) possibly due to the release of dark exudates from the explant's base (Ruffoni et al 2003). With the use of AC, darkening appeared to be reduced (Figure 2c).…”

“…It is known that both genotype and growth regulators significantly affect rooting in myrtle. Ruffoni et al (2003) obtained 45-50% rooting in myrtle clones PA2, DCCOD1 and AR6 in which IAA and IBA were used. Hatzilazarou et al (2003) reported clonal differences in rooting that 96% of microshoots of myrtle clone-A rooted on WPM medium containing 0.5 mg L -1 IBA while 100% of microshoots of myrtle clone-B rooted on the same medium but containing 1.0 mg L -1 IAA.…”

“…Several plant species including myrtle secrete phenolic substances during in vitro culture and these phenolic substances inhibit the development of the plant (Ruffoni et al 2003;Yağcı Tüzün et al 2013). Activated charcoal (AC) has been widely used in the micropropagation studies that the secretion of phenolics is encountered.…”

“…The plant growth regulators such as IBA and naphthalene acetic acid (NAA) were successfully used for the rooting of micro-cuttings in myrtle (Nobre 1994;Parra & AmoMarco 1998). However, Ruffoni et al (2003) reported that the micro-shoots of myrtle released dark exudates from the explant base during in vitro culture. It is well known that phenolic substances secreted by plants cause the darkening of explants, the decrease in the rooting rate and the slowdown of development.…”

In this study, a micropropagation approach was developed for a commercially important myrtle clone 'Aşı Mersin' in Turkey. The effects of different concentrations of thidiazuron (TDZ), 6-benzylaminopurine (BAP) and naphthalene acetic acid (NAA) on shoot formation and the effect of activated charcoal on rooting were studied. The most of the shoots were obtained on Murashige and Skoog (MS) medium containing 0.3 mg L -1 TDZ + 0.1 mg L -1 NAA in the 1 st subculture (3.8 shoot), and from MS with 0.3 mg L -1 TDZ + 0.01 mg L -1 NAA in the 2 nd subculture (4.0 shoot). The explants were rooted in ½MS containing indole-3-butyric acid (IBA), NAA and activated charcoal (AC). IBA applications induced more rooting than NAA. The medium supplemented with 1.0 mg L -1 IBA + 2.0 g L -1 AC resulted in the highest rooting ratio (80%). Addition of AC into the medium resulted in slight increase in the rooting ratio, significant increase in shoot length, and reduced darkening in the rooting area. Acclimatization was successful for 86% of the rooted plants.

“…The processing of myrtle fruit as a dried spice, mainly marketed in Central Italy and Middle East, also requires berries of good size for aesthetic and market reasons. Moreover, all ornamental uses of myrtle plants benefit from well-visible fruit [53]. Fruit peduncle length is substantially linked to easy fruit detachment both by hand and by machine [54].…”

Interest in myrtle (Myrtus communis L.) by food, cosmetics, and pharmaceutic industries generated the integration of biomasses harvested from wild populations as raw materials with yields of cultivated orchards. The domestication process is reviewed considering shoot, fruit, and leaf biometric characters of selections obtained in three steps of the program. The first step started in Sardinia (Italy) in 1995 by the analysis of wild germplasm variability. Seventy accessions were the object of the first studied population of mother plants. Agamic propagation tests, as well quality evaluations of fruit and leaves, were integrated into the first step. In the second step, a field of comparison of forty-two agamically propagated cultivars functional to biomass production and to food uses was planted and evaluated for phenotypic characters. In the third step, a new population of twenty selections was obtained by open cross-pollination of some of the cultivars and further phenotypic selection in seedling population. In this review, the three populations are compared for biometric shoot, leaves and fruit characters, in order to verify the pressure of domestication process on these traits. Wild populations showed high variability only partially used during the first step, while the hybridization may create new variability for use in the genetic improvement of myrtle.

The Myrtle (Myrtus communis L.) is an evergreen shrub typical of the Mediterranean area; it is an interesting plant with multipurpose use. The ornamental use takes into account the production of green cut branches for indoor decoration and production of pot plants for gardening. In this species, there is a great variability in the natural germplasm around the Mediterranean coasts for type and size of fruit, plant architecture, leaf size and internode length. Selected genotypes have been successfully sterilized and cultured in vitro. The shoots were multiplied on MS (16) salts and vitamins, with 0.5 mg/L BA and 0.2 mg/L IAA. Clones showed variation of multiplication rate and rooting percentage. IAA or IBA at 0.5 mg/L increased the rooting percentage and noticed differences in root number and length. The sucrose concentration can affect rooting, such as light intensity during the in vitro rooting phase can modulate biomass production and chlorophyll content. The combination of these factors enhanced the frequency rate of acclimatization.
