“…This fall in stomatal conductance is a consequence of stomatal closure. It should be noted that stomatal conductance has been used in several studies to detect the effects of water deficit on the functioning of the photosynthetic system (Beniken et al, 2013).…”

“…In addition, these results agreed with those obtained in Ziziphus lotus (Zouaoui et al, 2013). According to Beniken et al, (2013) and Rodriguez-Gamir et al, (2010), the decrease in stomatal conductance causes a reduction in transpiration and, consequently, a decrease in photosynthesis. It should also be noted that the chlorophyll a content is affected in a highly significant manner under prolonged water stress.…”

The present study belongs to the program of biodiversity conservation inside BouHedma national Park. Among the plant species in this park, Rhus tripartita (Ucria) Grande, Anacardiaceae, has several interests. Drought tolerance of R. tripartita seedlings subject to different levels of water stress: T (100% FC; 50% FC (S1); 25% FC (S2) and severe (S3) (No watering) based on photosynthetic gas exchange, chlorophyll content and biochemical analysis (soluble sugars and proline) was examined. A highly significant decrease was recorded in photosynthetic gas exchanges, in particular the stomatal conductance which has been diminished to zero with the intensity of water stress (S3). Similarly, leaf transpiration and photosynthetic assimilation are highly affected. These changes were accompanied by a reduction in chlorophyll pigment content (Cha and total chlorophyll content) and stabilization of Chb content. In contrary to that, the water stress induced an accumulation of organic solutes (soluble sugars and proline) in leaves and roots of young plants.

“…In the Souss-Massa region, clementine mandarin fruits mature in September for the early varieties, in October for the mid-early, in November for the mid-season and in December for the late-maturing ones [53,54]. However, to avoid the peak production of November and obtain high market prices early in the season, growers withhold irrigation during fruit maturation to boost sugar accumulation and induce early fruit maturation [53,55,56]. However, studies on the DI strategy to be used in the region, the adequate duration and degree of stress to be applied without hampering tree performance, and the resulting effect on fruit yield and quality, as well as on soil salinity and water saving are scarce.…”

Water scarcity is the most constraining factor for crop production, especially in arid and semi-arid areas of Mediterranean countries such as Morocco. Within these conditions, different water-saving strategies using deficit irrigation (DI) were tested on two six-years old clementine varieties (‘Sidi Aissa’ and ‘Orogrande’). These DI strategies were applied during the second part of fruit growth and during fruit maturation and included: the control treatment (Cntl), in which the trees received 100% of crop evapotranspiration (ETc) for the entire irrigation season; regulated deficit irrigation (RDI), with an application of 75% of ETc (RDI-1); partial rootzone drying (PRD), with an alternating irrigation between the two root system halves for 3–4 (PRD-3/4) and 7 (PRD-7) days, with an application of 50% crop water requirements; and RDI-2, with an application of 50% of crop water needs during fruit maturation. The results indicate that the trees preferably absorb the water from the upper 0–30 cm-depth soil profile and that fruit drop was increased by PRD for ‘Sidi Aissa’, whereas RDI-1 had no effect on this parameter. The DI strategies had no effect on fruit drop for ‘Orogrande’. The PRD reduced fruit size, yield and fruit juice content, with the effect being more pronounced on ‘Sidi Aissa’. The RDI-1 had no effect on fruit yield for ‘Orogrande’ but reduced it for ‘Sidi Aissa’. RDI-2 had no effect on yield, fruit size or fruit juice content. The DIs tested increased water use efficiency and enhanced fruit maturation as a result of increased juice sugar content and reduced acidity. The PRD tends to increase salt accumulation in the rootzone. Overall, ‘Orogrande’ was less sensitive to water stress and was more water-use efficient, and, under the semi-arid conditions of the experimental zone, PRD should not be used on clementine.
