Abstract Environmental stresses including salinity, drought, cold, warmer temperatures, alterations in precipitation patterns, fluctuations of weather events, and increasing insect disease infestations negatively affect crop production nutritional values. This situation becomes further complicated due to the changing climatic conditions, thus raising concern about food security worldwide. Some worst‐case projections indicated that by 2100, CO 2 concentrations will reach 950 parts per...
Nitric oxide (NO) is a well-accepted signaling molecule that has regulatory effects on plants under various stresses. Salinity major issue adversely affects plant growth and productivity. The current study was carried out to investigate changes in the growth, biochemical parameters, yield of wheat response NO donors, namely sodium nitroprusside (SNP) (2.5 5.0 mM) arginine (10 20 mM), two salinity levels (1.2 mM 85.5 NaCl). stress significantly decreased lengths weights parts (shoot, tiller,...
Salinity is a global conundrum that negatively affects various biometrics of agricultural crops. Jasmonic acid (JA) phytohormone reinforces multilayered defense strategies against abiotic stress, including salinity. This study investigated the effect JA (60 μM) on two wheat cultivars, namely ZM9 and YM25, exposed to NaCl (14.50 dSm-1) during consecutive growing seasons. Morphologically, plants primed with enhanced vegetative growth yield components. The improvement by priming associated...
Under natural conditions, crops typically suffer from severe challenges due to the increasing of abiotic and biotic stresses which severely affect plant growth reduc crop yield. The present study investigated single combined impacts Sclerotinia sclerotiorum salinity stress on common bean (Phaseolus vulgaris L.) seedling is scarcely studied. evaluated in vitro vivo influence two tolerant Trichoderma isolates, T. koningii harzianum against S. under stress. results showed ability grow sporulate...
Prospective involvement of metal oxide nanomaterials as a prominent agriculture practice for improving existing crop production directed the present investigation synthesizing ZnO and TiO2 an attempt to enhance transplants some Solanaceae crops. The morphological characterizations prepared indicated that hydrothermal synthesized was produced in nanorod structure with average aspect ratio 7. However, SEM TEM micrographs microwave evident it has nanoparticle diameter 43 nm. BET results...
Salinity is among the most significant threats hindering global food security. The impact of Trichoderma, biochar, and combination on Spinach plants under salt stress conditions was investigated. Our results confirmed that (75, 150 mM) negatively affected morphological physiological parameters such as shoot (26.4%, 45.9%), root length (16.1%, 51.2%), fresh dry weights shoot, membrane stability index (9.8%, 18.5%), relative water content(4.5%, 16.8%), chlorophyll content, mineral contents,...
The phytopathogenic basidiomycetous fungus, Rhizoctonia solani, has a wide range of host plants including members the family Poaceae, causing damping-off and root rot diseases. In this study, we biosynthesized spherical-shaped silicon dioxide nanoparticles (SiO2 NPs; sized between 9.92 19.8 nm) using saffron extract introduced them as potential alternative therapeutic solution to protect wheat seedlings against R. solani. SiO2 NPs showed strong dose-dependent fungistatic activity on...
Abstract The purpose of the present study is to investigate role hydrogen sulfide (H 2 S), in improving resistance common bean salt stress. Method shows that seeds were soaked water and two concentrations sodium hydrosulfide (50 100 µM) for 8 h. After 25 days from sowing, pots irrigated with NaCl (75 150 mM) until end experiment. Results revealed H S relieved stress by decreasing growth inhibition photosynthetic characteristics, increasing osmolyte contents (proline glycine betaine)....
Microbial biostimulants (MBs) promote plant growth and stress tolerance in a sustainable manner. However, precise field trials of MBs are required natural setting with range crop varieties to harness the benefits on yield improvement. This study investigated effects two MBs, Trichoderma album Bacillus megaterium, an onion cultivar's growth, nutritional qualities, antioxidant properties, potentials under conditions for successive years. Before transplantation, bulbs were gelatin-coated 2.0...
Increasing ultraviolet (UV) radiation is causing oxidative stress that accounts for growth and yield losses in the present era of climate change. Plant hormones are useful tools minimizing UV-induced plants, but their putative roles protecting tomato development under UVC remain unknown. Therefore, we investigated underlying mechanism pre-and post-kinetin (Kn) treatments on plants stress. The best dose Kn was screened preliminary experiments, this tested further experiments. significantly...
To our knowledge, the role of exogenous fluoride (F-) on aluminum (Al)-stress mitigation in plants has not been investigated yet. In this experiment, barley (Hordeum vulgaris) seedlings were exposed to excessive Al3+ concentrations (aluminum chloride, 0.5, 1.0, 2.0, 3.0, and 4.0 mM) with without (0.025% sodium fluoride) explore possible roles alleviation Al-toxicity.Overall, Al-stress caused inhibition growth production photosynthetic pigments. Principal component analysis showed that...
The utilization of nanoparticles in agriculture land is widely increasing worldwide. present study takes advent from converting the rice husk waste to silica (SiNPs) be used two years field experimented as fertigation treatment against reducing irrigation by drip system eggplants. In this respect, experiments comprised three regimes (i.e., 60, 80, and 100% crop evapotranspiration, ETc)) four levels SiNPs (0, 100, 200, 300 mg L−1). results indicated that limited reduced plant fresh weight,...

Abstract Bisphenol A (BPA) and p -nitrophenol (PNP) are emerging contaminants of soils due to their wide presence in agricultural industrial products. Thus, the present study aimed integrate morpho-physiological, ionic homeostasis, defense- antioxidant-related genes response tomato plants BPA or PNP stress, an area research that has been scarcely studied. In this work, increasing levels soil intensified drastic effects on biomass photosynthetic pigments plants. Moreover, induced osmotic...
Magnetic fields are an unavoidable physical factor affecting living organisms. Lettuce seeds (Lactuca sativa var. cabitat L.) were subjected to various intensities of the static magnetic field (SMF) viz., MF0 (control), SMF1 (0.44 Tesla (T), SMF2 (0.77 T), and SMF3 (1 T) for three exposure times (1, 2, 3 h). SMF-treated seedlings showed induction in growth parameters metabolism comparing control. All photosynthetic pigments induced markedly under SMF, especially chlorophyll a. SMF at...
Elevated CO2 (eCO2 ) is one of the climate changes that may benefit plant growth under emerging soil contaminants such as heavy metals. In this regard, morpho-physiological mechanisms underlying mitigating impact eCO2 on beryllium (Be) phytotoxicity are poorly known. Hence, we investigated and Be interactive effects metabolism two species from different groups: cereal (oat) legume (alfalfa). stress significantly reduced photosynthetic attributes in both species, but alfalfa was more...
