“…Additionally, the reduction of grain weight under the water deficit may be due to the decrease of grain-filling duration and then lower dry matter accumulation or a reduced rate and duration of starch accumulation in the endosperm (Zhao et al, 2020). Grain yield was reported to be decreased under water stress due to the decrease of number of spikes m -2 , number of kernels spike -1 and thousand kernel weight (Abd El-Rady et al, 2020 andMahdavi et al, 2022).…”

Water scarcity is one of the most significant constraints to wheat production in Egypt and around the world. Therefore, twenty genotypes and four cultivars of bread wheat were tested under normal irrigation (six irrigations including planting irrigation) and water deficit stress (two irrigations at 21 and 45 days after the planting irrigation) during the 2020/2021 and 2021/2022 growing seasons at Shandaweel Agricultural Research Station, Sohag, Egypt. Each irrigation treatment was considered a separate experiment in the randomized complete block design. The two seasons and two water treatments showed sufficient genetic variability among the studied genotypes. The number of days to heading and maturity, plant height, yield and its components traits significantly decreased under water deficit stress. The genotypes G13 and G17 significantly outperformed all studied genotypes and checked cultivars for grain yield under normal irrigation and water stress conditions. The genotypes G16, G2, G12, G9, G17, G20, G18, G8, G10 and G5 as well as cultivars Sids 14, Sokoll and Kasuko showed stress susceptibility index (SSI) <1 and they can be used as a source of water deficit tolerance in a breeding program. Genotypic main effect plus genotype by environment interaction (GGE) Biplot analysis revealed that the genotypes G13 and G17 had high yielding ability but genotype G17 showed more stability and tolerance under water stress conditions. Therefore this study concluded that the genotypes G13 and G17 were suitable genotypes to be cultivated under water shortage conditions and could be used to enhance the wheat breeding program for water deficit stress tolerance.

“…According Mahdavi et al, (2023), different stress tolerance indices including stress tolerance index (STI), stress susceptibility index (SSI), mean productivity index (MP), stress tolerance (TOL), harmonic mean (HARM) and geometric mean productivity (GMP) were evaluated to determine the degree of tolerance in both cultivars. Yield index (YI) and yield stability index (YSI) were evaluated according to F. Khan and Mohammad, (2016),.…”

The toxic effects of lead (Pb) on plants, animals, and humans have made it a subject of interest for environmental scientists. Recent literature has shown how Pb affects the morpho-physiological and biochemical attributes of rice. Therefore, it is important to mitigate Pb stress to restore rice agro-morphological traits and yield. For that purpose, current study involved growth of two cultivars of Japonica rice (JP-5) and Indica rice (Super Basmati) grown in pots under Pb stress (50 mg/kg) as lead chloride and the application of ascorbic acid coated quantum dots (AsA-QDs) in two suspensions (50 ppm and 100 ppm) to mitigate the stress. Pb stress declined T/P, GY, TKW, protein, TPC, and TAC by 11.11%, 18.22%, 18.22%, 40.19%, 59.66%, and 17.75% respectively in JP-5. These traits were recovered by 33.33% (T/P), 5.73% (GY), 2.03% (protein), and 13.19% (TPC) in Pb*QD1 treatment. Whereas in SB, Pb concentrations reduced PH, T/P, BY, GY, TKW, total sugars, reducing sugars, non-reducing sugars, starch, proteins, and TPC by 19.76%, 21.43%, 11.01, 11.01%, 7.52%, 38.09%, 7.24%, 13.96%, 11.97%, and 40.39% respectively. These traits were recovered by 14.29% (T/P), 15.49% (GY), 9.25% (total sugars), 109.52% (reducing sugars), 8.31% (non-reducing sugars), 31.72% (starch), 25.91% (proteins), and 7.075% TPC in Pb*QD1 treatment. It is recommended that AsA-QDs can be used as potential sources to remediate Pb toxicity in crops for sustainable growth development.
