Salinity is the major environmental factor limiting plant growth and productivity. Under salinity conditions, plant growth is affected by a number of factors such as hormonal and nutritional imbalance, ion toxicity, physiological disorders, susceptibility to diseases, etc. Plant growth under stress conditions may be enhanced by the application of microbial inoculation including plant growth pro...

introduction nowadays, salinity is one of the limiting factors for crop production in arid and semi-arid regions. on the other hand, sorghum (sorghum bicolor l.) is a self-pollinated and short-day plant, which partly has been adapted to salinity and water stress conditions; also play an important role in humans, livestock and poultry nourishments. all studies have showed the positive effects of...

ornithine is a non-proteinogenic amino acid, which plays an essential role in the metabolism of plants. regard to the chirality of the molecule, physiological response of the plant cells to its two enantiomers have not been widely investigated yet. in the present study, suspension-cultured tobacco cells were treated with 1 mm of d- and lenantiomers of ornithine in normal conditions as well as u...

trichoderma spp. are known as efficient plant growth promoting agents. hence, enrichment of soil by appropriate population of trichoderma is useful and important for effective plant growth promote. present study aimed to investigate the plant growth promoting effects of five strains of the genus trichoderma species include: trichoderma harzianum tr6, t. harzianum t22, t. asperellum t34, t. atro...

Salinity of soil is a major abiotic stress limiting the crop production and growth of peppermint. The aim of study was assessment the plant growth regulators efficacy (salicylic acid (SA), jasmonic acid (JA), brassinosteroids (BRs), and non-application of hormone as control) on physiological traits of peppermint under salinity stress (0, 30, and 60 mM). The experiment was conducted using the co...

Abiotic stress has a growing impact on plant growth and agricultural activity worldwide. Specific plant growth promoting rhizobacteria have been reported to stimulate growth and tolerance to abiotic stress in plants, and molecular mechanisms like phytohormone synthesis and 1-aminocyclopropane-1-carboxylate deamination are usual candidates proposed to mediate these bacterial effects. Paraburkhol...

lentil is considered as salinity sensitive species and is adversely affected in response to the salt stress in terms of growth and yield. this pot experiment was conducted to determine the effect of exogenous salicylic acid (sa) application on physiology, growth, yield and yield components of lentil grown under salt stress in greenhouse conditions, in a factorial arrangement based on randomized...

zinc has previously been reported to alleviate salinity stress in plants. in this study, we monitored various biomass and chlorophyll fluorescence parameters to determine the optimum zinc sulfate concentration that can be used as foliar spray to alleviate salinity stress in glycine soja. the plants subjected to a series of salinity levels (nacl concentration of 0, 100, 200, and 300 mmol l-1), a...
