“…There were no discernible differences in the decrease in the SWC in plants stressed for two and three weeks compared to that of the plants stressed for one week. Melaouhi et al [51] studied the response of two-year-old 'Arbequina' and 'Empeltre' cultivars to mild (30% field capacity) and severe (50% field capacity) stress and found that both treatments resulted in a significant reduction in the SWC, but no differences or interactions between cultivars or treatments and cultivars were observed. Using the SWC as a benchmark, the current study confirmed that drought stress had an equal impact on all the cultivar groups, with the severity directly related to the duration of the water shortage.…”

“…The data presented showed that the PRO and TSS increased at high regimes of drought as in the cases of MS75 and SS50. Under water deficit conditions, both osmolytes (PRO and TSS) act as respiratory substrates to alleviate stress tolerance (Yooyongwech et al, 2016;Melaouhi et al, 2021). It could be the neutral nature of osmolytes that accumulates to prevent the denaturation of protein and cell membrane in the cytosol during drought conditions for osmotic adjustments and conservation of turgor pressure as described by Hebbache et al (2021).…”

“…Reductions in F v /F m imply reduced efficiency of the photochemical conversion process, which may suggest possible damage to and inhibition of PSII activity [58]. In general, a strong correlation between net photosynthesis and stomatal conductance has been reported in olive varieties [11,59]. However, according to Brito et al (2018), olive trees that have been under water deficit exhibit a quicker recovery of the photosynthetic rate compared to stomatal conductance, even if they have been pre-exposed to drought conditions before [54].…”
