salinity is one of the most important abiotic stresses that limit crop growth and productivity. this study focuses on the effects of different strains of plant growth promoting rhizobacteria (pgpr) on the physiological responses of two wheat cultivars under normal and salt stress conditions. the wheat cultivars selected include one which is tolerant to salinity (kavir) and one which is sensitiv...

o investigate the role of selenomethionine (SeMet) in regulating drought tolerance strawberry plants, we explored effects SeMet on antioxidative enzymes, water physiology and fruit quality plants under stress (DS). In this study, used variety ‘Sweet Charlie’ as material investigated through foliar spraying pot experiments. The results showed that DS obviously enhanced activities antioxidant enz...

Water salinity and drought are the major abiotic stresses limiting turf grass growth. On the other hand, shortage of waterresources and salinity of water and soil in the arid and semi-arid zones such as Iran, are the restricting factors in developinglawn turf grasses. An experiment was conducted to evaluate the combined effects of water salinity and deficit irrigation ontall fescue (Festuca aru...

the tuberose cut flower is much less longevity in postharvest. the less vase life due to stress of deficit carbohydrate and quick respiration on inflorescence. in this study, effectiveness factors, sucrose, cacl2, al2so4 and re-cut the stems. in current research two separate experiments were arranged as a factorial based on compeletly randomized design. the first experiment were added to all ex...

Abscisic acid (ABA) is a key component of the signaling system that integrates plant adaptive responses to abiotic stress. Overexpression of Arabidopsis molybdenum cofactor sulfurase gene (LOS5) in maize markedly enhanced the expression of ZmAO and aldehyde oxidase (AO) activity, leading to ABA accumulation and increased drought tolerance. Transgenic maize (Zea mays L.) exhibited the expected r...

To evaluate genetic variation of wheat (Triticum aestivum) affected by heat and drought stress on eight Australian wheat genotypes that are parents of Doubled Haploid (HD) mapping populations at the vegetative stage, the water stress experiment was conducted at 65% field capacity in growth room. Heat stress experiment was conducted in the research field under irrigation over summer. Result show...

Domestic soybean production is getting weaker due to drought stress which affects all aspects of plant growth and metabolism, besides using adaptive varieties, increasing nutrition, especially potassium, also tolerance drought. The research aimed examine the effect potassium application on morphophysiological two varieties under stress. was conducted in a plastic house, Deli Serdang Regency, No...

kentucky bluegrass (poa pratensis l.) is one of the most widely used turfgrasses for home lawns, golf courses, parks, and athletic fields in temperate climates. oxidative stress caused by drought stress is a major limiting factor for grass cultivation in arid and semi-arid regions. the objective of this study was to investigate whether prohexadione-calcium (pro-ca) may play a role in promoting ...
