Recent studies have introduced seed priming with H2O2 as an effective technique to alleviate abiotic stresses in plants. In the current study, accomplished at Faculty of Sciences, Shahrekord University, seeds of medicinal plant Artemisia aucheri were primed with H2O2 (0, 10, 50, 90 and 140 µM) and grown under salt stress (0 and 150 mM NaCl) for one month. Results showed a decrease in H2O2 and m...

Seed priming improves vigor, but priming agents may differ greatly in their effectiveness. The present study was performed to unravel the physiological basis of vigor improvement by priming sunflower achenes with pre-optimized levels of hydrogen peroxide (H2O2), salicylic acid (SA), thiourea (TU), gibberellic acid (GA3), ascorbic acid (AA), sodium chloride (NaCl), freezing and heating. Most of ...

Chilling stress is an important constraint for maize seedling establishment in the field. To examine the role of salicylic acid (SA) and hydrogen peroxide (H2O2) in response to chilling stress, we investigated the effects of seed priming with SA, H2O2, and SA+H2O2 combination on maize resistance under chilling stress (13°C). Priming with SA, H2O2, and especially SA+H2O2 shortened seed germinati...

Salinity is a dominant obstacle to the proper germination of seeds, growth seedlings, and, consequently, production crops. The priming seeds with different treating agents can efficiently impart salinity tolerance. Kidney bean nutritious and popular vegetable crop in world. Literature shows that salt stress negatively disturbs kidney beans. In present research, we investigated potentiality sali...

Soil alkalinity is a severe threat to crop production globally as it markedly retards plant growth. Different techniques are used mitigate alkaline stress, but priming considered the most appropriate. The current study was carried out in complete randomized design (CRD) evaluate effect of different on maize grown under levels stress. experiment comprised treatments stress (AS) including, contro...

Plants are constantly challenged by various abiotic stresses that negatively affect growth and productivity worldwide. During the course of their evolution, plants have developed sophisticated mechanisms to recognize external signals allowing them to respond appropriately to environmental conditions, although the degree of adjustability or tolerance to specific stresses differs from species to ...

Plants treated with chemical compounds can develop an enhanced capacity to resist long after being subjected to (a)biotic stress, a phenomenon known as priming. Evidence suggests that reactive oxygen species (ROS) and reactive nitrogen species (RNS) coordinately regulate plant stress responses to adverse environmental conditions; however, the mechanisms underlying this function remain unknown. ...

Exposure of neutrophils to a range of cytokines augments their response to subsequent agonist-induced activation of the respiratory burst. We have examined the effects of several of these factors, both singly and in combination, on the priming of f-met-leu-phe (FMLP) and complement C5a-stimulated neutrophil H2O2 production, using a whole blood flow cytometric assay designed to minimize artefact...

Hydrogen peroxide was initially recognized as a toxic molecule that causes damage at different levels of cell organization and thus losses in cell viability. From the 1990s, the role of hydrogen peroxide as a signaling molecule in plants has also been discussed. The beneficial role of H2O2 as a central hub integrating signaling network in response to biotic and abiotic stress and during develop...

Salinity is affecting plant growth and development. Low concentration of hydrogen peroxide (H2O2) has shown to be effective against various stress factors. In this study, effect different H2O2 priming methods on growth, physiological biochemical parameters in three wheat varieties (NKÜ Lider, Sultan-95, Tosunbey) under salt were investigated. Salt (0 160 mM NaCl) was applied gradually 100 µM (-...
