Leaf morpho-physiology and phytochemistry of olive trees as affected by cultivar type and increasing aridity

The olive species (Olea europaea L.) is an ancient traditional crop grown under rainfed conditions in the Mediterranean Basin. In response to growing national and international demand for oil, cultivars are introduced into highly arid new bioclimatic areas. Subsequently, morpho-physiology phytochemistry of trees potentially changing among cultivar types geographical conditions. present work, we have undertaken assessment on impacts location leaf trees. Thus, leaves two most cultivated tree varieties, Chemlal Sigoise, were collected from three regions (Setif, Batna, Eloued) with increasing aridity Algeria. Leaf samples analyzed using standard physiological experiment, colorimetric method, a chromatography assay. Leaves both exhibited significant variance terms shape index but not tissue density, specific weight, area. Photosynthetic pigment contents affected by type location, lowest content recorded Sigoise Setif region. Compared Batna regions, dried Eloued region showed higher levels total polyphenol, flavonoid, tannin, as well better antioxidant capacity. Liquid chromatography-mass spectrometry analysis all extracts identified following phenolic acids major compounds: oleuropein, naringin, apigenin-7-O-glucoside, kaempferol, quercetin, quercitrin, luteolin-7-O-naringenin, quinic acid. Lower found p-Coumaric acid, trans-Ferulic hyperoside, rutin, apigenin, caffeic protocatechuic o-Coumaric gallic Also, epicatechin catechin+ cultivar. organic displayed promising anti-cancer activity that was solvent polarity. Briefly, although soil mineral deficiency morpho-physiological parameters, sustained chemical richness, good antioxidant, anti-tumoral capacity leaves. Furthermore, findings revealed regardless genotype, there impact morpho-physiology, bioactivity, composition, which may consequently modulate growth oil production
