“…They are intended for the production of olive oil (Godini et al, 2011). The choice of these varieties by growers is due to several reasons, mainly their erected habit and low vigor, their precocity and their oil richness in comparison with autochthone varieties as well as their excellent quality (Allalout et al, 2009;Russo et al, 2014;Mansouri et al, 2016).…”

-The purpose of this study is the evaluation of flavor profiles of monovarietal virgin olive oils (VOO) produced in the Oriental region of Morocco via the characterization of volatile compounds, using SPME-GC/MS technique, and the determination of total phenolic content (colorimetric method). The study concerns oils of three European olive cultivars (Arbosana, Arbequina and Koroneiki) which were recently introduced in Morocco under irrigated high-density plantation system. GC/MS aroma profiles of analyzed VOOs showed the presence of 35 volatile compounds. The major compounds in such oils are C6 compounds produced from linoleic and linolenic acids via lipoxygenase pathway such as trans-2-hexenal, cis-2-hexenal, cis-3-hexen-1-ol, trans-3-hexen-1-ol, trans-3-hexen-1-ol acetate, hexanal and 1-hexanol in different proportions depending on the cultivar (p < 0.05). In addition, statistical analyses indicate that the analyzed VOOs have different aroma profiles. Arbequina oil has a high proportion of compounds with sensory notes "green" and "sweet" giving it a fruity sensation compared to Arbosana and Koroneiki. In parallel, Arbosana and Koroneiki oils are rich in phenolic compounds and provide relatively bitter and pungent tastes to these oils.Keywords: virgin olive oil / volatile compounds / phenols / solid phase micro extraction Résumé -Profils organoleptiques d'huiles d'olive vierges monovariétales produites dans la région orientale du Maroc. Le but de cette étude vise l'évaluation des profils organoleptiques des huiles d'olive vierges monovariétales produites dans la région orientale du Maroc par la caractérisation des composés volatils et la détermination de la teneur en phénols totaux. Il s'agit d'huiles d'olive de trois cultivars d'origine européenne (Arbequina, Arbosana et Koroneiki) récemment introduites au Maroc en irriguée super-intensif. Les profils aromatiques obtenus par GC/MS des huiles analysées montrent la présence de 35 composés volatils. Les principaux composés présents dans ces huiles sont les composés C6, tels que le trans-2-hexénal, le cis-2-hexènal, le cis-3-hexén-1-ol, le trans-3-hexén-1-ol, l'acétate de trans-3-hexén-1-ol, le 1-héxanol et l'hexanal à des proportions différentes selon le cultivar (p < 0,05). En outre, les analyses statistiques indiquent que les huiles analysées ont des profils aromatiques différents. L'huile d'Arbéquina présente une forte proportion des composés offrant des notes sensorielles « vert » et « sucré » lui conférant une sensation de fruité par rapport à l'Arbosana et Koroneiki. En parallèle, les huiles Arbosana et Koroneiki sont riches en composés phénoliques et apportent des goûts relativement amer et piquant à ces huiles.

“…These advantages are responsible for the rapid spreading of this type of olive cultivation system in all olive-growing countries (Tous et al, 2003;Tous et al, 2010). However, there is still very little information available about the response of cultivars where this system has been adopted (Arbequina, in particular) to the specific climatic and cultural conditions of central Italy, which may differ from those of origin (Allalout et al, 2009;Godini et al, 2011). Furthermore, there is little information on adaptation of local cultivars to this new cultivation system (Camposeo et al, 2008;Proietti et al, 2011).…”

In recent years, there has been an increase in interest in super high-density (SHD) olive (Olea europaea L.) groves because they offer early entry into production, increased productivity and the possibility of using modified mechanical vine harvesters. This study was carried out in a young SHD olive grove to examine vegetative, histo-anatomical and productive characteristics and oil quality of the Spanish Arbequina and Italian Maurino and Leccino cultivars, characterized by low, low-to-medium and high vigor, respectively. Arbequina had low vigor and limited development in height and width, as well as a high leaf/wood ratio. Maurino had a canopy volume similar to that of Arbequina and, despite a great tendency to grow in height, had low vigor, a rather compact vegetative habitus, but good lighting in the canopy and high production efficiency. In Maurino, a greater palisade parenchyma height and a larger exposed lateral surface area of the palisade parenchyma cells were observed. In the fourth year after planting, fruit production of Arbequina was about 30 % less than Leccino and Maurino. The oil content on a dry weight basis was slightly higher in Arbequina and Maurino than in Leccino. Oil quality was good for all cultivars.

“…Moreover, in the literature some vegetative and productive parameters are considered in order to assess the varietal response since considerable differences are observed among different cultivars, mainly depending on both growth habit and vigour [1,2,4,10]. In fact the benefit of these new systems mainly depends on the availability of cultivars with compact habit and slow canopy growth, owned by Arbequina and Arbosana, two Spanish cultivars on which these systems were calibrated up to now [2]. It is crucial to know the morphology and the dynamics of sprout elongation of an olive cultivated genotype in order to fully assess its suitability for a high-density olive orchard.…”

The new high-density cropping systems (>1200 trees ha −1 ) represent a very interesting proposal for olive orchard profitability. It is crucial to know the morphology and the dynamics of sprout elongation of a cultivar in order to fully assess its suitability for a high-density olive orchard. For this reason we planned a research on two cultivars, Coratina and Arbequina, in a high-density orchard. The apical sprouts elongation of Arbequina early stopped at fruit set without a further step, while Coratina showed a little growth flux after pit hardening. Similar trends showed the lateral proleptic sprouts. Only the sylleptic sprouts of both cultivars had a second period of activity. In all cases, the sprouts elongation finished at the end of summer, when oil accumulation started. Coratina showed higher apical shoot growth and internodes mean length than Arbequina. On the contrary, Coratina showed lower lateral proleptic shoot growth and nodes number than Arbequina, but the same internodes mean length. No significant differences were observed between cultivars for growth, nodes number and internodes mean length of sylleptic shoots. The differences observed between the two cultivars could be explained considering their different vigour. The introduction of this innovative cropping system is allowed to register a considerable reduction of production costs. The result is a considerable increase in the economic performance of the olive grove and a consequent reduction in the unit cost for kg of oil. These data are very useful for varietal choice and field management in high-density orchards and then for new olive breeding programs.
