“…Safflower is an essential oilseed crop that can moderately tolerate against several environmental stresses including drought (Mohammadi et al, 2016 management practices affected the oil content of safflower cultivars. Among the environmental stresses, water deficient condition increase protein and decrease oil contents of safflower (Nabipour et al, 2007;Amini et al, 2014).…”

“…Furthermore, tolerant plants accumulate soluble compatible substances including proline and soluble sugars without hampering enzyme activities which, thereby, decreases the water potential [ 15 ]. Thus, tolerant plants modulate the adverse effects of drought stress through photosynthetic adjustment, osmolytes accumulation, and activities of genes that encode antioxidant enzymes [ 16 ]. Under drought stress, plants hamper transpiration phenomenon through different mechanisms such as closing the stomata, and developing stomatal resistance parallel with decreasing stomatal conductivity [ 17 ].…”

Improving the extent of adaptation and the choice of the most tolerant cultivar is the first step to mitigating the adverse effects of limited water, especially in susceptible plants such as strawberries. To address this issue, two commercial strawberry cultivars (Camarosa and Gaviota) were compared when irrigated to match 100, 75, 50, and 25% field capacity (FC) to simulate the control, slight, moderate, and severe drought stress conditions, respectively. Drought stress induced the reduction of total chlorophyll, carotenoid, relative water content, and phenolic content significantly, whereas the activity of antioxidant enzymes, electrolyte leakage, osmolyte accumulation, and oxidative markers upsurged progressively in drought severity-dependent behavior. Gaviota produced more proline, hydrogen peroxide as a marker of membrane lipid peroxidation and disposed of by higher electrolyte leakage, significantly. On the other hand, Camarosa having higher soluble carbohydrates as well as enzymatic and non-enzymatic antioxidants could be considered a drought-tolerant cultivar. Genotypic variation between these cultivars could be used in breeding projects to promote drought-tolerant strawberries in the future.

“…These findings are in line with Kassahun et al (2010) , who demonstrated that delayed leaf senescence often confers tolerance to post flowering moisture stress in sorghum. RWC is often used as a screening tool for drought tolerance, as water content and water potential are considered physiologically appropriate indicators of drought effects ( Mohammadi et al, 2016 ). Tolerant genotypes often maintain higher values of RWC in stress, as evident in the present study by genotypes A1 (92.3 ± 2.13), EC-523368-2 (87.3 ± 2.52), Bhima (86.5 ± 2.99) and GMU 2347 (84.7 ± 1.46).…”

Oilseeds with high productivity and tolerance to various environmental stresses are in high demand in the food and industrial sectors. Safflower, grown under residual moisture in the semi-arid tropics, is adapted to moisture stress at certain levels. However, a substantial reduction in soil moisture has a significant impact on its productivity. Therefore, assessing genetic variation for water use efficiency traits like transpiration efficiency (TE), water uptake, and canopy temperature depression (CTD) is essential for enhancing crop adaptation to drought. The response of safflower genotypes (n = 12) to progressive soil moisture depletion was studied in terms of water uptake, TE, and CTD under a series of pot and field experiments. The normalised transpiration rate (NTR) in relation to the fraction of transpirable soil water (FTSW) varied significantly among genotypes. The genotypes A-1, Bhima, GMU-2347, and CO-1 had higher NTR-FTSW threshold values of 0.79 (R2 = 0.92), 0.74 (R2 = 0.96), 0.71 (R2 = 0.96), and 0.71 (R2 = 0.91), respectively, whereas GMU-2644 had the lowest 0.38 (R2 = 0.93). TE was high in genotype GMU-2347, indicating that it could produce maximum biomass per unit of water transpired. At both the vegetative and reproductive stages, significant positive relationships between TE, SPAD chlorophyll metre reading (SCMR) (p < 0.01) and CTD (p < 0.01) were observed under field conditions by linear regression. The genotypes with high FTSW-NTR thresholds, high SCMR, and low CTD may be useful clues in identifying a genotype’s ability to adapt to moisture stress. The findings showed that the safflower genotypes A-1, Bhima, GMU-2347, and CO-1 exhibited an early decline and regulated water uptake by conserving it for later growth stages under progressive soil water depletion.
