“…This was evidenced by the reduction in all growth parameters reported in the current study. In alignment with other studies ( Henry et al., 2016 ; Elnahal et al., 2022 ; Fouda et al., 2022 ), our results showed that water stress reduced PH and the number of tillers. This could be due to the decrease in cell turgor, which inhibited cell division and expansion.…”

Rice (Oryza sativa L.) is a major cereal crop and a staple food across the world, mainly in developing countries. Drought is one of the most important limiting factors for rice production, which negatively affects food security worldwide. Silica enhances antioxidant activity and reduces oxidative damage in plants. The current study evaluated the efficiency of foliar spray of silica in alleviating water stress of three rice cultivars (Giza178, Sakha102, and Sakha107). The seedlings of the three cultivars were foliar sprayed with 200 or 400 mg l-1 silica under well-watered [80% water holding capacity (WHC)] and drought-stressed (40% WHC)] conditions for two summer seasons of 2019 and 2020. The obtained results demonstrated that drought stress caused significant decreases in growth, yield, and physiological parameters but increases in biochemical parameters (except proline) of leaves in all rice cultivars compared to well-irrigated plants (control). The roots of drought-stressed seedlings exhibited smaller diameters, fewer numbers, and narrower areas of xylem vessels compared to those well-watered. Regardless of its concentration, the application of silica was found to increase the contents of photosynthetic pigments and proline. Water relation also increased in seedlings of the three tested rice cultivars that were treated with silica in comparison to their corresponding control cultivars when no silica was sprayed. Foliar application of 400 mg l-1 silica improved the physiological and biochemical parameters and plant growth. Overall, foliar application of silica proved to be beneficial for mitigating drought stress in the tested rice cultivars, among which Giza178 was the most drought-tolerant cultivar. The integration of silica in breeding programs is recommended to improve the quality of yield and to provide drought-tolerant rice cultivars under drought-stress conditions.

“…Lemongrass yield in the 2 nd experimental season was greater than that of the 1 st one due to more appropriate environmental conditions. In this concern, similar results were obtained regarding irrigation regimes by Chakraborty et al (2010) on Cymbopogon flexuosus, Also, bio stimulant chitosan application to tolerate water deficit was mentioned by Katiyar et al, 2015;Malekpoor et al, 2016;Rabelo et al 2019 ;Farouk and EL-Metwally, 2019;Moolphuerk and Pattanagul, 2020;and Fouda et al, 2021.…”

Growth attributes, yield and essential oil (EO) of lemongrass plant (Cymbopogon citratus (DC.) Stapf) in addition to some water relations and the economic return were assessed in response to the mutual effect of coefficients of cumulative pan evaporation (CPE) as a practical basis of irrigation scheduling at four levels (1.00, 0.85, 0.70 and 0.55 CPE) and foliar spraying with chitosan as antitranspirant compound (0, 50, 100 and 150 ppm). For this purpose, field study was implemented under sandy soil conditions during consecutive seasons of 2018 and 2019. Results exhibited that fresh and dry biomass per plant consequently, the herbage and dry yield per fed were enriched by irrigation scheduling at 1.00 and 0.85 CPE. However, irrigation scheduling at 0.70 and 0.55 CPE reduced all studied growth, yield attributes, oil yield and transpiration rate. EO yield per plant and per fed besides the oil main components were significantly enhanced by 1.00 or 0.85 CPE interacted with chitosan spraying at all levels in both harvests for the experimental seasons. The interaction between irrigation scheduling at 0.85 CPE and foliar spraying with 100 or 150 ppm chitosan significantly increased yield, oil productivity, and bioactive constituents particularly citral %. The premier productivity of irrigation water was recorded at 0.85 CPE compared with the other irrigation treatments. Hence, the optimum water requirement of 0.85 CPE interacted with foliar spraying of chitosan at 100 ppm as antitranspirant compound improved lemongrass yield, EO, economic return, water return and the productivity of irrigation water under water deficit conditions.

“…Results were in harmony with Farooq et al (2012) and Fouda et al (2022) who explain the significantly decreasing effects of drought on the growth performance of studied genotypes by causing inhibited changes in cell metabolisms. The Giza-716 cultivar fit to grow under drought conditions although it have a low fresh and dry weight of shoot and root under 100% FC, moderate weight under drought conditions, and the percent decrease is lower than other cultivars.…”

This work was carried out for studying the drought tolerance ability of five Egyptian faba bean cultivars (Sakha 1, Sakha-4, Nubaria-1, . Cultivars were planted under three levels of field capacity (FC);100% ,75% and 50% FC respectively with split-plot design in two winter seasons; 2019/2020 and 2020/2021. Growth, yield and its attributes characters, chlorophyll content were measured. Stress tolerance indices (geometric mean productivity (GMP), drought susceptibility index (DSI), mean productivity (MP), yield stability index (YSI), and tolerance (TOL) and genetic variations were calculated. Five primers of Inter-Simple Sequence Repeat (ISSR) molecular markers were used to detect the variability among cultivars. Results showed that drought caused a significant reduction in growth, yield, and its attributes characters and chlorophyll content. Giza843 has a high yield, and its attributes characters under all watering treatments. At the same time, Sakha1 and Sakha4 showed increased sensitivity to drought conditions. Sakha4 gave high yield and its component under normal conditions while Giza716 cultivar showed high yield under severe conditions. The phenotypic coefficient of variation (PCV) value was higher than the genotypic coefficient of variation (GCV) value for all studied traits. One hundred seeds weight trait showed the highest PCV (71.15%), GCV (70.86%), and Genetic Advance (GA) (145.38), while the root length trait showed the lowest PCV (6.49%), GCV (6.04%), and GA (11.59). Higher values of heritability and GA were obtained for pods and leaves number/ plant, pods weight / plant, and 100 seeds weight. Results of tolerance indices indicated that Giza 716 and Giza843 cultivars (cv.) were drought-tolerant cultivars through they had the highest values of MP, GMP and YSI , the lowest values of TOL and values lower than unity of DSI. ISSR analysis identified 37 loci and heterozygosity ranged from 0.736 to 0.892 with an average of 0.827. Fourteen bands were polymorphic, with 37.83% percent of polymorphism. Polymorphism information con-tent (PIC) values were ranged from 0.75 to 0.89, averaging 0.84. Ten unique bands were used as molecular markers, most obtained by HB12 primer. ISSR markers' cluster analysis divided studied cultivars into three main clusters. Genetic similarity and dendrogram were in harmony with yield traits results.
