    Abstract Purpose: Nowadays, the problem of water scarcity increased due to the increase of aridity, which enhances the use of non-conventional waters. The irrigation with treated wastewater was primarly developed. Research method: In the present research, we compared the quality of pomegranate fruits harvested from two ‘Gabsi’ orchards managed according to two different cultural practices such as: organic (O) and conventional irrigated with treated wastewater (WW). We determine the soil and fruit characteristics. Findings: Results showed that the organic soil was richer in Fe, Mn and Mg; however, irrigated with WW was richer in Cu, Zn, and Cd with the absence of Ag and Ni in both soils. The analysis of fruits demonstrated that organic ones were richer in Cu, Zn and Mn. Mg content was similar in both fruits. Hg, Ni, Cd, and Fe were not present in fruits. The BCF of Cu and Zn were higher in organic fruits, contrary to Mg. Furthermore, the highest values of the SSC/TA ratio were recorded in organic fruits with no pathogenic contamination for both fruits. Limitations: No limitations were founded. Originality/Value: This study illustrates the possibility of treating wastewater in the irrigation of pomegranates without adverse effects.

    Abstract Purpose: The evaluation of the response of three old pear cultivars (’Meski Arteb’, ‘Bouguedma’ and ‘Alexandrine’) to drought was performed through some physiological traits and leaf characteristics. This work aimed to highlight the behavior of these cultivars under water stress conditions. Research method: The experiment was carried out in a greenhouse under controlled conditions by the application of three water stress levels as a complete randomized block. Plants showed moderate water deficit after 10 days without watering and severe stress after 20 days without watering. Control plants were kept well watered. Findings: Data showed a similar cultivar response to water stress but with various degrees. The relative water content and the water potential of leaves decreased with the water stress severity in all cultivars. Stomatal conductance and photosynthetic assimilation followed the same path with water status parameters, and ‘Alexandrine’ showed the highest level of gas exchange parameters. Chlorophyll content and total soluble sugars concentration of leaves decreased in response to drought increase. However, the proline content and leaf characteristics were unaffected except for ‘Bouguedma’ cultivar for which leaf area and succulence were reduced under severe stress. Limitations: No limitations were founded. Originality/Value: the three cultivars behaved differently against drought, these traits can be exploited for further breeding programs to face climate change impact.

    Abstract Purpose: Nowadays with the precipitation scarcity induced by climate change, the use of non-conventional water resources in irrigation is needed such as saline water. The irrigation of salt tolerance species like olive could be adopted with potassium foliar spray. In this work we present how olive plants modulate sodium potassium balance and metabolism to mitigate salt stress. Research method: A pot experiment was conducted to assess how potassium nitrate modify Na/K ratio and biochemical compounds in olive plants. One-year-old olive plants (cv Chemlali) irrigated with a saline water (10g/L) were subjected to three treatments: K0, K1 and K2 (0, 1 and 2% of potassium nitrate foliar spray, respectively). Findings: Results showed differences between treatments. The mineral composition particularly the sodium and potassium content of leaves and roots revealed that the K1 and K2 treatments slightly increased K/Na in leaves and decreased in roots. Moreover, the salt stress was moderate through the osmotic adjustment. The accumulation of osmolytes (proline and soluble sugars) decreased by k1 and K2 treatments. Secondry metabolites (phenols) showed an increase by K1 and K2. Lipid peroxydation was also reduced by treatments especially in young leaves and then increased. In conclusion, potassium can be recommended in order to mitigate the harmful effects of salinity. Research limitations: No limitations were founded. Originality/Value: In the condition of current water scarcity the saline water could be used with potassium application.

    Abstract The productivity of olive trees in arid and semi-arid environments is closely linked to irrigation. It is necessary to improve the efficiency of irrigation techniques to optimise the amount of olive fruit produced in relation to the volume of water used. Partial root-zone drying (PRD) is a water saving irrigation technique that theoretically allows the production of a root-to-shoot signal that modifies the physiology of the above-ground parts of the plant; specifically reducing stomatal conductance (gs) and improving water use efficiency (WUE). Partial root-zone drying has been successfully applied under field conditions to woody and non-woody crops; yet the few previous trials with olive trees have produced contrasting results. Thirty year-old olive trees (Olea europaea 'var. Chetoui') in a Tunisian grove were exposed to four treatments from May to October for three-years: 'control' plants received 100% of the potential evapotranspirative demand (ETc) applied to the whole root-zone; 'PRD100' were supplied with an identical volume of water to the control plants alternated between halves of the root-zone every ten-days; 'PRD50' were given 50% of ETc to half of the root-system, and; 'rain-fed' plants received no supplementary irrigation. Allowing part of the root-zone to dry resulted in reduced vegetative growth and lower yield: PRD100 decreased yield by ~47% during productive years. During the less productive years of the alternate bearing cycle, irrigation had no effect on yield; this suggests that withholding of water during 'off-years' may enhance the effectiveness of irrigation over a two-year cycle. The amount and quality of oil within the olive fruit was unaffected by the irrigation treatment. Photosynthesis declined in the PRD50 and rain-fed trees due to greater diffusive limitations and reduced biochemical uptake of CO2. Stomatal conductance and the foliar concentration of abscisic acid (ABA) were not altered by PRD100 irrigation, which may indicate the absence of a hormonal root-to-shoot signal. Rain-fed ...
