Worldwide sustainable development is threatened by current agricultural land change trends, particularly by the increasing rural farmland abandonment and agricultural intensification phenomena. In Mediterranean countries, these processes are affecting especially traditional olive groves with enormous socio-economic costs to rural areas, endangering environmental sustainability and biodiversity. Traditional olive groves abandonment and intensification are clearly related to the reduction of olive oil production income, leading to reduced economic viability. Most promising strategies to boost traditional groves competitiveness—such as olive oil differentiation through adoption of protected denomination of origin labels and development of value-added olive products—rely on knowledge of the olive varieties and its specific properties that confer their uniqueness and authenticity. Given the lack of information about olive varieties on traditional groves, a feasible and inexpensive method of variety identification is required. We analyzed leaf spectral information of ten Portuguese olive varieties with a powerful data-mining approach in order to verify the ability of satellite’s hyperspectral sensors to provide an accurate olive variety identification. Our results show that these olive varieties are distinguishable by leaf reflectance information and suggest that even satellite open-source data could be used to map them. Additional advantages of olive varieties mapping were further discussed.

“…Results of this study demonstrated that the method of extraction used is appropriated for the quantification of the concentration of these compounds in stem samples. The profile described for stem is likely to the found in leaf in which, also this four triterpenic compounds are found [11] although with concentration in leaf higher that in stem. The presence of MA, OA, EO and UO indicate that β-amyrin synthase is present in this organ and it is implied in the biosynthesis pathway of MA, OA and EO and that α-amyrin synthase is also present in this organ and it is implied in biosynthesis of UO.…”

Background: Pentacyclic triterpenes are plant secondary metabolites that have many applications for health of the people. Methods: In this work, we determine by a HPLC-UV/Vis and HPLC-MS what pentacyclic triterpenes are found in stem and root of cv. Picual olive tree, a variety typically grown in the area of Jaén (Spain). Moreover, the concentration of these compounds along fruit ripening also has been determined in both organs. Results: Maslinic acid (MA), oleanolic acid (OA), erythrodiol (EO), and uvaol (UO) have been found in stem. OA is the compound that shown the highest concentration in this organ. MA, betulinic acid (BA), OA and ursolic acid have been found in root. In general, BA has the highest concentration in this organ. BA had not been detected in other olive tree organs. Conclusion: The evolution showed by the concentrations of these compounds during ripening suggests the existence of two different phases: the first related with the increment in weight of fruit and the second related with the ripening following. The evolution found in stem is different to the found in root and we believe that are related with the functions of these compounds in each organ.

“…Concurrently with alterations in temperature, climate change will also trigger variations in current precipitation patterns, modifying not only the precipitation levels but also changing the typical periods where rainfall occurs, causing periods of drought stress and flooding events [63,[127][128][129][130][131]. Moreover, these changes will likely be accompanied by an increase in water demand as the global population grows [81].…”

Metabolomics-Based Evaluation of Crop Quality Changes as a Consequence of Climate Change

Fruit composition determines the fruit quality and, consequently, consumer acceptance. As fruit quality can be modified by environmental conditions, it will be impacted by future alterations produced by global warming. Therefore, agricultural activities will be influenced by the changes in climatological conditions in cultivable areas, which could have a high socioeconomic impact if fruit production and quality decline. Currently, different stresses are being applied to several cultivated species to evaluate their impact on fruit metabolism and plant performance. With the use of metabolomic tools, these changes can be precisely measured, allowing us to determine changes in the patterns of individual compounds. As these changes depend on both the stress severity and the specific species involved and even on the specific cultivar, individual analysis must be conducted. To date, the most-studied crops have mainly been crops that are widely cultivated and have a high socioeconomic impact. In the near future, with the development of these metabolomic strategies, their implementation will be extended to other species, which will allow the adaptation of cultivation conditions and the development of varieties with high adaptability to climatological changes.
