Drought alters plant physiology, morphology, and biochemical pathways, necessitating effective mitigation strategies. Strigolactones (SLs) are phytohormones known to enhance growth under abiotic stress. However, their specific impact on drought stress in maize remains unclear. This study aimed determine the optimal SL concentration for mitigating two hybrids (HY-1898, FH-1046). Maize plants were subjected 60% field capacity a pot experiment. After 40 d, different concentrations (0, 0.001, 0.01, 0.1 mg L−1) of synthetic analogue GR24 applied evaluate effects features, photosynthesis attributes, osmolyte accumulation hybrids. Results showed that exogenous application significantly increased photosynthetic pigments Chlorophyll content, gas exchange characteristics, net CO2 assimilation rate, stomatal conductance, water use efficiency, antioxidant activities enhanced by GR24. Leaf ascorbic acid total phenolics also with application. Organic osmolytes, such as glycine betaine free proline, elevated both Yield-related parameters, including cob diameter, weight, number seeds per cob, plant, Our findings highlight potential foliar mitigate promote grain yield concentration-dependent manner. The minimum against was determined be 0.01 L−1. Overall, could serve sustainable approach tolerance agriculture.

Olive (Olea europaea L.) is a crop of enormous economic and cultural importance. Over the years, worldwide production olive oil has been decreasing due to various biotic abiotic factors. The current drop in resulting from climate change raises concerns regarding fulfillment our daily demand for led significant increase market prices. In future, there will be higher chance that we face severe shortage oil, which could harm both sector food supply. As groves cover more than 5 million hectares European Union alone, need preserve context extreme climatic events imperative. drought considered one most limiting factors agriculture, drought-resistant varieties sustainable irrigation strategies are being developed mitigate impact on productivity secure future supply oil. This review focuses recently gained insights into stress trees through omics phenomics approaches unravelling mechanisms may lead developing new tolerant against elicited by changes growing systems.

Assessment of Various Nanoprimings for Boosting Pea Germination and Early Growth in Both Optimal and Drought-Stressed Environments

Plants, Год журнала: 2024, Номер 13(11), С. 1547 - 1547

Опубликована: Июнь 3, 2024

One of the main climate change-related variables limiting agricultural productivity that ultimately leads to food insecurity appears be drought. With use a recently discovered nanopriming technology, seeds can endure various abiotic challenges. To improve seed quality and initial growth 8-day-old field pea seedlings (cv. NS Junior) under optimal artificial drought (PEG-induced) laboratory conditions, this study aimed assess efficacy priming with three different nanomaterials: Nanoplant Ultra (Co, Mn, Cu, Fe, Zn, Mo, Se), Ca-Si (Ca, Si, B, Fe), Sulfur (S). The findings indicate treatments have positive impact on indicators, early plant growth, resilience in plants established both drought-stressed conditions. Nevertheless, all showed effect, but their modes action varied. proved most effective whereas were efficient stress. After evaluation, examined comprehensive nanomaterials may utilized as agents for boost germination, crop environmental

Abstract Drought stress remains a serious concern in Oryza sativa L. var indica , cultivar Satabdi (IET4786) production, particularly during the earliest growth phases, ultimately affecting yield due to recent trend of delayed rain arrival West Bengal, India. This study aimed develop cost-effective strategy improve drought tolerance capacity rice seedlings by priming seeds with flavonoid-enriched extract (FEE) French marigold ( Tagetes patula ) petals withstand initial milieu. The morpho-physiological and biochemical responses were evaluated perceive efficacy alleviating water stress-induced untoward effects. findings revealed that mechanical IET4786 FEE (50 mg/mL for 30 min) significantly improved seedling survival against 14 days. After 24 h recovery from stress, primed seed-derived exhibited morphological, physiological, biochemical, redox parameters compared derived unprimed under net house conditions. In search mechanistic insights, seed increased proline content endorsing Δ 1 -pyrroline-5-carboxylate synthetase activities, endorsed methylglyoxal clearance homeostasis improving glyoxalase I II activities through restoring glutathione (GSH) level, enhanced polyamine accumulation leaves endure stress.

Enhancing Drought Tolerance in Wheat Cultivars through Nano-ZnO Priming by Improving Leaf Pigments and Antioxidant Activity

Sustainability, Год журнала: 2023, Номер 15(7), С. 5835 - 5835

Опубликована: Март 28, 2023

Climate change, global warming, stagnant productivity of wheat and food security concerns owing to frequent spells drought stress (DS) have necessitated finding biologically viable drought-mitigation strategies. A trial was conducted test two promising cultivars (Ujala-16 Zincol-16) that were subjected pre-sowing priming treatments with different doses ZnO nanoparticles (NPs = 40, 80, 120 160 ppm) under 50% 100% field capacity (FC) conditions. The NPs prepared a co-precipitation method characterized through X-ray diffraction (XRD) scanning electron microscope (SEM). For comparison purposes, untreated seeds sown as the control treatment. response variables included botanical traits (lengths, fresh dry wrights root shoot), chlorophyll (a, b total) contents, antioxidant proline contents nutrients status cultivars. results showed DS significantly decreased all cultivars, while NPs, especially ppm dose, remained superior by increasing at FC. In addition, increased (1.73 mg/g FW in Ujala-16 1.75 Zincole-16) (0.70 0.71 total content (2.43 2.46 improving activity content. Moreover, plant such Ca, Mg, Fe, N, P, K, Zn Zincol-16 cultivar. To summarize, remains Ujala-16, (120 dose FC) increases growth mineral both varieties. Thus, this combination might be recommended growers after testing further in-depth evaluation more NPs.
