Opis:
Olea europaea is the most emblematic tree of the Mediterranean region. It has been cultivated for about 6000 years for its fruit, oil, wood, and for medicinal and cultural purposes. The research data concerns the monumental olive trees in the region. The oldest and biggest known trees are in Lebanon, Israel, Greece, Albania and Italy. The oldest of those, ‘Sisters of Noahʼ (Lebanon) are believed to be 5000–6000 years old. The most numerous groups of monumental olives were reported from Apulia in Italy and Albania. The oldest and biggest olive trees could be remnants of ancient plantations from the Hellenic and Roman times, but this hypothesis should be confirmed in a detailed study.

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 olive tree is represented in Tunisia by two varieties: var. sylvestris (wild olive trees) and var. europaea (cultivated olive trees including diverse cultivars). Seed (stone) size and shape analysis may provide the basis for relationships between varieties and cultivars as well as to study the responses to environmental conditions. A semi-automated method of image analysis allows to obtain data related with magnitudes descriptive of stone size and shape and to compare between wild and cultivated olives. Also, the effect of bioclimate on size and shape was analyzed in some cultivars. Stone size and shape presents high variability. In cultivated trees stones are larger. Mean seed image area is 0.38 and 0.75 cm² for wild and cultivated plants respectively. Roundness and circularity were compared as to their potential to define seed shape. Mean values were higher for circularity, but roundness is more variable reaching higher values in some individuals and varieties. Roundness is more useful to compare seed shape variations. In addition, climate factors affect the stone characteristics in cultivars; those of sub-humid region having larger stones. Phenotypic parameters of stone are discriminating parameters for the analysis of intra-specific, intra-varieties and intra-cultivars variability in Olea europaea.

Opis:
Oleuropein is a secoiridoide monoterpene. It is found primarily in all parts of the Olea europaea L. tree, mostly in its unripe fruit and leaves. It has a number of beneficial effects on the human body, being readily absorbed from the gastrointestinal tract due to its hydrophilic properties. The paper presents a simple, rapid and precise method for the assay of oleuropein in herbal formulations and the European Olive leaf extract. Chromatographic separation was performed using a C-18 column with an acetonitrile/water 20/80% vol. mixture as the mobile phase. The method has a wide range of linearity between 0.05 and 1.5 mg/mL, very good repeatability of retention time, and accuracies between 95.8 and 103.3%. Its limit of detection is 0.04 mg/mL. The developed method was tested on two herbal formulations which are commercially available in Poland.

Opis:
Plants belonging to the family Oleaceae have been traditionally used in treatment of various inflammatory skin disorders. One of the most well-known species is Olea europaea L. (olive), cultivated in the Mediterranean countries. Another species is Ligustrum vulgare L. (common privet), occurring particularly in Northern Europe and Asia. The aim of the study was a comparison of the composition of aqueous and ethanolic extracts from leaves of O. europaea and L. vulgare (HPLC-DAD-MS), and determination of the total content of phenolics and flavonoids, as well as the content of the major compound, oleuropein. Secondly, we aimed to study the protective effect of extracts on reactive oxygen species (ROS) production by human fibroblast cells (NHDF), cell viability (MTT assay), and apoptosis rate (Annexin V/propidium iodide staining) after UVA-irradiation. The phytochemical analysis allowed us to identify compounds belonging to the groups of flavonoids, phenylpropanoids and secoiridoids in the extracts. The compounds from the group of lignans (olivil) were identified as being unique to O. europaea extracts. Echinacoside, ligustroflavone and ligustaloside A were identified in L. vulgare extracts in contrast to olive preparations. It was established that the aqueous and ethanolic extracts from leaves of both species, except the privet aqueous extract at a concentration of 5 μg/ml, did not show any significant inhibition of ROS production after UVA-irradiation in the model of NHDF cell line. The aqueous extracts of both species at concentrations of 5 and 25 μg/ml had a protective effect on the viability of UVA-treated cells in contrast to the ethanolic extract. In conclusion, no significant difference in the activity of olive and privet leaf extracts has been observed, which suggests that both plant materials’ extracts, particularly aqueous ones, are effective herbal medicines and photoprotectors, which – to some extent – confirms the use of their preparations in skin disorders.

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:
An efficient and accurate method of sampling, recovery, and enumeration of epiphytic bacterial populations are of fundamental importance for their precise estimation. In this study, effectiveness and reliability of processing methods, sampling type, sample storage, and plating techniques, for the recovery of the epiphytic bacterial populations, were evaluated. Pseudomonas savastanoi pv. savastanoi, the causal agent of olive knot disease, and two olive sub-species were used. Bulk-leaf sampling allowed for a higher number of the bacterial recovery. The use of a lab blender was the most effective and reliable method among the four commonly used processing methods. A short storage of leaf samples was possible through freezing. Bacterial survival was not influenced as long as the samples were processed within 5 days and frozen without a buffer. No difference was observed among the drop and spread platings, suggesting that one of them can be used and the choice depends on the cost and time required.
