“…It is estimated that 900 million olive trees cover over 10 million hectares worldwide (Sesli and Yeğenoğlu 2009). Dermechea et al (2013) stated that Mediterranean countries produce approximately 2.5 million metric tons/year olive oil.…”

Solid olive mill residue (SOMR), a lignocellulosic material obtained from olive oil extraction, is a potential attractive source of biomass for energy generation. Although SOMR can be directly combusted, a pretreatment can reduce the oxygen and moisture contents of raw SOMR for efficient energy generation. Torrefaction is a promising thermal pretreatment method for improving fuel characteristics of raw SOMR. In this study, torrefaction characteristics of SOMR were investigated at three different torrefaction temperatures and holding times. Ultimate and proximate analysis results of torrefied SOMR were compared with dried SOMR. Results indicate that an increased torrefaction temperature and holding time can lead to a more qualified solid fuel with higher carbon content, increased higher heating value (HHV), and reduced oxygen content. Further, increased HHV and removal of volatiles are indicators of more energy-dense solid fuel obtained from SOMR. Experimental results revealed that moderately severe torrefaction conditions with holding times not exceeding 30 minutes are suitable for torrefaction of SOMR.

“…In order to solve this problem, variations within and between populations of taxa were pointed out by using some statistical analyses such as Statistica version 8.0 for principal component analysis (PCA) and cluster analysis (CA) using an unweighted pair group method (UPGMA) analysis and Popgen 32. According to the results of statistical analyses, it was attempted to draw the most possible borders of taxa based on the DNA bands obtained from RAPD analyses (Sesli and Yegenoglu, 2009;Açık et al, 2009;Kavalcıoglu et al, 2010) and a better phenetic classification by using molecular characters showing high correlations with each other.

The genus Quercus (Fagaceae) includes the most important woody plants with decidious and evergreen species in Northern hemisiphere. They have a problematic taxonomy because of widespread hybridization between the infrageneric taxa. Turkey is one of the most important region of the world according to oak species number and variation. In this study, species belonging to evergreen oaks in Turkey were investigated to solve taxonomic problems and to design the limit of taxa by using random amplified polymorphic DNA (RAPD) data. Here, three species of evergreen oaks known as Quercus coccifera, Quercus ilex and Quercus aucheri were studied in all area located and made the comparison within and among species studied using ten RAPD markers. As a result; it can be stated that the presence of the three species in Ilex section is clear. Furthermore, existence of two infraspecific taxa or two seperate taxa in species level within Q. coccifera may be quite possibly considered.

“…Although more than 2600 distinct olive cultivars have been described, this may be an underestimation, given of the lack of data on minor local cultivars in many olive-growing areas. This broad genetic diversity has been characterized in different eastern and western Mediterranean countries based both on morphological and on molecular characters (Cipriani et al, 2002;Owen et al, 2005;Rallo et al, 2005;Sarri et al, 2006;Cordeiro et al, 2008;Ipeck et al, 2009;Fendri et al, 2010;Roubos et al, 2010;Sesli and Yeğenoğlu, 2010). Molecular methods for olive cultivar fingerprinting have been demonstrated to be effective, but microsatellite or simple sequence repeat (SSR) analysis is becoming the preferred choice for its high discriminatory power and simpler interpretation (Bracci et al, 2011).…”

ABSTRACT. Seventy-seven olive accessions corresponding to 25 cultivars from the Extremadura region of Spain were studied using four microsatellite or SSR markers in order to fingerprint them, and evaluate genetic similarity and relationships between local and introduced olive cultivars. The number of alleles per locus ranged from 4 to 8, with a mean of 6.25 alleles per primer pair (a total of 25 alleles). The observed heterozygosity ranged from 0.58 to 0.95, while the expected heterozygosity varied between 0.68 and 0.83. The polymorphism information content values ranged from 0.63 to 0.79. The mean polymorphism information content value of 0.70 for the SSR loci provided sufficient discriminating ability to evaluate the genetic diversity among the cultivars. The SSR data allowed unequivocal identification of all the cultivars; a combination of three SSR markers was sufficient to discriminate all 25 olive cultivars. A dendrogram was prepared, using the unweighted pair-group method with arithmetic mean clustering algorithm; it depicted the pattern of Genetic diversity of olive cultivars by microsatellite markers relationships between the cultivars. Most of the local cultivars grouped according to their geographic origin. No clear clustering trends were observed when the morphological traits of fruit endocarps or fruit use of cultivars were employed as analysis criteria. We conclude that there is a high level of variability among local olive cultivars from the Extremadura region at both the morphological and molecular levels; these data should be useful for identifying and distinguishing local germplasm.
