Olea europaea L. is a well-adapted species to cyclic drought events, still at considerable expense of carbon reserves and CO2 supply. To study the role of abscisic acid (ABA) as a promoter of drought adaptability, young potted olive trees subjected to three drought-recovery cycles were pre-treated with ABA. The results demonstrated that ABA pre-treatment allowed the delay of the drought effects on stomatal conductance (gs) and net photosynthesis (An), and under severe drought, permitted the reduction of the non-stomatal limitations to An and the relative water content decline, the accumulation of compatible solutes and avoid the decline of photosynthetic pigments, soluble proteins and total thiols concentrations and the accumulation of ROS. Upon rewatering, ABA-sprayed plants showed an early recovery of An. The plant ionome was also changed by the addition of ABA, with special influence on root K, N and B concentrations. The improved physiological and biochemical functions of the ABA-treated plants attenuated the drought-induced decline in biomass accumulation and potentiated root growth and whole-plant water use efficiency after successive drought-rewatering cycles. These changes are likely to be of real adaptive significance, with important implications for olive tree growth and productivity.<\/jats:p>","DOI":"10.3390\/plants9030341","type":"journal-article","created":{"date-parts":[[2020,3,9]],"date-time":"2020-03-09T05:37:34Z","timestamp":1583732254000},"page":"341","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Foliar Pre-Treatment with Abscisic Acid Enhances Olive Tree Drought Adaptability"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2370-6084","authenticated-orcid":false,"given":"C\u00e1tia","family":"Brito","sequence":"first","affiliation":[{"name":"CITAB-Centre for the Research and Technology of Agro-Environmental and Biological Sciences, Universidade de Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9612-0909","authenticated-orcid":false,"given":"Lia-T\u00e2nia","family":"Dinis","sequence":"additional","affiliation":[{"name":"CITAB-Centre for the Research and Technology of Agro-Environmental and Biological Sciences, Universidade de Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"}]},{"given":"Helena","family":"Ferreira","sequence":"additional","affiliation":[{"name":"CITAB-Centre for the Research and Technology of Agro-Environmental and Biological Sciences, Universidade de Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5825-559X","authenticated-orcid":false,"given":"Jos\u00e9","family":"Moutinho-Pereira","sequence":"additional","affiliation":[{"name":"CITAB-Centre for the Research and Technology of Agro-Environmental and Biological Sciences, Universidade de Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2482-7873","authenticated-orcid":false,"given":"Carlos M.","family":"Correia","sequence":"additional","affiliation":[{"name":"CITAB-Centre for the Research and Technology of Agro-Environmental and Biological Sciences, Universidade de Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Brito, C., Dinis, L.-T., Moutinho-Pereira, J.M., and Correia, C.M.
