    Opis:
    The wild olive (O. europaea L. subsp. oleaster) is widely distributed along the coastal zones of Anatolia (Asia Minor). The Aegean Region (Western Anatolia) in particular has a rich olive population, including genuine wild individuals as well as feral forms. Oleaster olives in situ, which have diverse morphological and pomological characteristics, differ from cultivated olives. The ripe olive fruit has a purple-black color because of the accumulation of anthocyanin. As in cultivated olives, the yellow color in ripe fruits of the oleaster olive is unusual. This yellow color in ripe fruits of oleaster olives has not been reported so far. Thus it is potentially significant for further breeding strategies. This paper assesses the morphological characteristics of two oleaster ecotypes (YO1 and YO2) with yellow fruits that were coincidentally located in the Đzmir Province. Significant differences are found between the two ecotypes both in terms of their quantitative characteristics as well as the oil content of their fruit. Fruit weight (1.2 g), length (15.5 mm), width (11.2 mm) and percentage of oil in dry weight (15.7%) are significantly higher in YO1. Apart from the differences between the quantitative stone characteristics, the stone morphology and surface texture are also considerably different. Besides potential agronomic considerations, they both have high potential for use as ornamental trees.

    Opis:
    The evergreen tree olive (Olea europaea L.) is the only species of the genus Olea that produces edible fruits with high ecological and economic value. This tree species has developed a series of physiochemical mechanisms to tolerate drought stress and grow under adverse climatic environments. One of these mechanisms is photosynthesis activities, so that as yet little information achieved about the relations between olive production and photosynthetic parameters under drought conditions. An experiment was carried out during two consecutive years (2015–2017) to study the response of 20 different olive tree cultivars (Olea europaea L.) to drought stress. Several parameters like net photosynthetic rate (PN), stomatal conductance (GS), transpiration rate (TE), photosynthetic pigments (total chlorophyll, chlorophyll a, b and carotenoid) and fruit yield were measured. The results of combined analysis of variance for fruit yield and other measured traits showed that year, drought treatment, cultivar main effects and their interactions were highly significant. The results indicated that drought stress reduced all traits, however GS (42.80%), PN (37.21%) and TE (37.17%) significantly affected by drought. Lower reduction in photosynthetic performance (PN, GS and TE) in the cultivar T7 compared to other olive cultivars allowed them to maintain better fruit yield. Principal component analysis (PCA) identified two PCs that accounted for 82.04 and 83.27% of the total variation in photosynthetic parameters under optimal and drought stress conditions, respectively. Taken together, mean comparison, relative changes due to drought and biplot analysis revealed that cultivars ‘T7’, ‘Roghani’, ‘Koroneiki’, ‘Korfolia’ and ‘Abou-satl’ displayed better response against drought stress. According to our results, one olive cultivar namely ‘T7’, could be used in olive breeding programs to improve new high yielding cultivars with drought tolerance for use in the drought-prone environments.

    Opis:
    Water is the most important environmental factor in growth and fruit yield of trees. To study the effect of deficit irrigation on reproductive characteristics and yield of seven superior olive genotypes of D1, Dd1, Gw, Ps1, Bn3, Bn6, and Ds17. The present research was accomplished in Dallaho Olive Research Station of Sarpol-e zahab, Kermanshah, Iran, in 2014 and 2015. Seven superior olive genotypes were studied in a randomized complete block design with three replicates and three irrigation regimes. The irrigation treatments included: 100% full irrigation (control), 75% deficit irrigation, and 50% deficit irrigation applied during the growth season. The results indicated that the genotypes had different reactions to the deficit irrigation regimes. Dd1 had the highest fruit weight, while the lowest fruit weight was observed in Ps1 and Gw. The highest fruit yield was found in Bn3, Bn6, and Dd1, while the lowest was observed in Ps1. As a result, Bn6 and Dd1 are introduced as the genotypes that are resistant to drought in the field.

    Opis:
    ‘Žutica’ is the most widespread olive variety of Montenegro, accounting for as much as 98% of olive trees in the southern part of Montenegrin coastal area – Bar subarea. The primary purpose of variety ‘Žutica’ is olive oil production due to its small fruits and high oil content, although it is also much appreciated as a table olive, prepared in local ways as green and black. As ‘Žutica’ is an old olive variety there are some phenotypic differences recorded in the fruit properties. Here we evaluated 22 accessions from the area of Bar and Ulcinj, where this variety is very widespread (almost mono-varietal), for 34 parameters of the fruit and endocarp. Significant differences in fruit properties were observed in the accessions. Average fruit size in nine accessions was above 3.5 g and in two accessions more than 4.0 g. Number of fruits per kg ranged from 224 to 330. Cluster analysis and principal component analysis (PCA) were used to group the accessions and evaluate the morphological variability. The accessions clustered into two groups, with two off group accessions of the highest fruit weight. The results showed differences among individuals, especially for large fruit accessions that should be investigated further.

    Opis:
    To tolerate harsh climatic conditions, olive tree Chetoui has developed some anatomic, physiologic and biochemical mechanisms. The aim of this study was to determine the indicators of stress in leaves, stems and roots growing under various climatic conditions. To protect against stress conditions this cultivar increased cuticle thickness, protective structures and building parenchyma tissues of leaves, woods and roots from the North to the South. The volatile compounds, extracted from northern and southern Chetoui leaves and roots, were analyzed by GC-FID and GC-MS. Great changes in volatiles were illustrated in the studied organs, by enrichment in phenolics and fatty acids for leaves and in hydrocarbons for roots of southern Chetoui. Also, a reduction in terpenes, alcohols and carbonylic compounds was noted in both southern samples. Moreover, minerals of all organs of Chetoui, varied in content and allocation, but their levels are the highest in leaves. The changes in volatiles might be affected by changes in the mineral elements uptake or accumulation under environment stress. A significant correlation was noted between phenolic compounds and sodium, nitrogen, and calcium contents. However, terpenoids was highly correlated with phosphorus content for all organs and studied areas. The detection of new volatiles, anatomical and mineral changes seem to be efficient indicators of adaptation of Chetoui to environment stress conditions.
