“…They found a negative and significant correlation (r=-0.797 ** ) between the percentages of silt and clay in the soil and olive shoot growth. Melgar et al (2009) indicated that soil salinity did not cause changes in any of the growth variables measured, including shoot length, whereas Aragues et al (2005) found significant decreases in trunk diameter growth with increases in soil salinity.…”

This experiment was conducted to explore the reasons of difference between 'Zard' olive orchard with the poor vegetative growth rate and fruit set and orchard with suitable vegetative growth rate and fruit set in relation to some soil and plant factors during two seasons. Note that assumptions were based on the overall canopy greenness of the olive trees, so experimental orchards in which the planted trees showed optimum leaf greenness were considered good situations for optimum vegetative growth and productivity. Remote sensing technologies based on normalized difference vegetation index (NDVI) were employed on olive orchards, and two orchards meeting the criteria of highest amount of greenness and lowest amount of greenness were selected. Length of current-year shoot (LCYS) and fruit set were considered indicators of tree vegetative growth and productivity, respectively. Results clearly indicated a significant difference between the two selected orchards in terms of canopy volume (CV), leaf nitrogen content (N), leaf potassium content (K), silt, sand, Sodium adsorption rate (SAR), available phosphorous (P avi ), total neutralizing value (TNV), electrical conductivity (EC), chloride (Cl), and Fe variables. A stepwise regression method was used to evaluate the effects of soil and plant variables on fruit set and LCYS. According to the obtained results, the main reasons for differences between two orchards in fruit set and vegetative growth was N and K deficiencies, soil salinity, and a high percentage of silt in the soil.

“…Tolerant cultivars are able to make exclusion of Na + and Cl -from shoots (Gucci et al, 1997) by restricting their accumulation in actively growing shoots and leaves (Melgar et al, 2009). Although, this tactic increases salt absorption but put a check on its translocation (Benlloch et al, 1991;Demiral, 2005).…”

Various transcriptome studies have remained useful in unraveling the complexity of molecular pathways regulating the oil biochemical contents and fruit characteristics of agronomic value in olive. Genes networks associated with plant architect and abiotic stress tolerance have been constructed due to robust genomic data generated by the tools of genomics. This, familiarity will accelerate the breeding programmes in making the selection of high yielding olive genotypes promptly and efficiently. Moreover, comparative transcriptome studies for endogeneous enzymes at different expression sites explicate the contribution of various pathways in phenol and lipid oxidation in olive. Recently, non-targeted metabolomics and metabolic profiling techniques have not only made the understanding of metabolic changes easy but also elucidate biomarkers in fruits related to agronomic parameters and abiotic stresses. However, the alteration in the architectural build up of phenotypes authenticates the conservation of their potential genetic links that will invoke interest for future olive breeding. IntroductionOlea europea is the most important tree of Mediterranean basin which consists 95% of globally cultivated olive trees (Loumou and

“…These authors also concluded that vegetative growth was more tolerant to salinity than fruit yield production. Melgar et al (2009) reported that mature trees of the tolerant cultivar Picual drip-irrigated under Mediterranean climate (mean annual precipitation around 700 mm) allowed using high saline irrigation waters (up to 10 dS m -1 ) for a long time (nine years) without affecting growth and yield. Winter leaching by rainfall of the salts accumulated in the root zone during the irrigation seasons was the main reason for the absence of negative effects with such high saline waters.…”

“…However, existing data on the effects of salinity on growth and yield of olive are scarce, especially for long-term experiments under field conditions (Aragüésetal. 2005;Cimato et al 2010;Gucci and Tattini 1997;Melgar et al 2009;Wiesman et al 2004).…”
