The compensation heat pulse (CHP) method is widely used to estimate sap flow and transpiration in conducting organs of woody plants. Previous studies have reported a natural azimuthal variability in sap flow, which could have practical implications in locating the CHP probes and integrating their output. Sap flow of several olive trees (Olea europaea L. cv. 'Arbequina') previously grown under d...
The motherland of the olive is considered as east Mediterranean Basin. Turkey partly located within this basin having a rich source biodiversity. Olive growing in carried out Aegean, Marmara, Mediterranean, Southeastern Anatolia and Black Sea Regions. Climatic factors determine cultivation limits which not very selective terms soil demand. In regions where olives are grown, climate prevails. Wi...
The olive (Olea europaea L.) is a typical important perennial crop species for which the genetic determination and even functionality of self-incompatibility (SI) are still largely unresolved. It is still not known whether SI is under gametophytic or sporophytic genetic control, yet fruit production in orchards depends critically on successful ovule fertilization. We studied the genetic determi...
The olive tree had been domesticated during the early Neolithic in the Near East, and more than 1000 different cultivars have been identified to date. However, examples of wild olive trees (Olea europaea oleaster) can still be found in the Mediterranean basin. Evidence of oleaster use for oil production can be found in historical and sacred texts, such as the Odyssey, the Holey Koran, and the H...
BACKGROUND Olive trees (Olea europaea subsp. europaea var. europaea) naturally grow in areas spanning the Mediterranean basin and towards the East, including the Middle East. In the Iranian plateau, the presence of olives has been documented since very ancient times, though the early history of the crop in this area is shrouded in uncertainty. METHODS The varieties presently cultivated in Ira...
Here we present the genome sequence and annotation of the wild olive tree (Olea europaea var. sylvestris), called oleaster, which is considered an ancestor of cultivated olive trees. More than 50,000 protein-coding genes were predicted, a majority of which could be anchored to 23 pseudochromosomes obtained through a newly constructed genetic map. The oleaster genome contains signatures of two O...
Anthocyanins (Anths) in olive (Olea europaea L.) fruits at different degrees of pigmentation were assessed nondestructively by measuring chlorophyll fluorescence (ChlF). The method is based on the comparison of the ChlF excitation spectra from olives with different pigmentation from green to green-red, reddish-purple, and purple. The logarithm of the ratio between the fluorescence excitation sp...
Introduction: Huntington's disease is a neurodegenerative disorder in which an increase in the global oxidative stress and a decrease in the antioxidant defense system are observed. Olea europaea's main phenolic components include oleuropein, dimethyl oleuropein, ligstroside and phenolic oleosides, which can be more than 140 mg per gram of fresh olives and 60-90 mg per gram of dried olive le...
We present the formulation, calibration and validation of a model to estimate photosynthetically active radiation (PAR) intercepted by olive (Olea europaea L.) canopies. The model calculates the PAR transmittance at any point located within the four central trees of the orchard. The spatial and time integration of this process allows calculation of PAR transmitted to the ground and, thus, the P...
In a grove in north-eastern Morocco 2020, severe root rot and crown symptoms were noticed on olive trees (Olea europaea). Pythium schmitthenneri was identified as the pathogen based conidia morphology cytochrome oxidase subunit II (COXII) gene sequence analysis. Koch's postulates verified by re-isolation of fungus P. from artificially inoculated seedlings after pathogenicity test. This is first...
