Salicylic acid alleviates the cadmium toxicity in barley seedlings.
Salicylic acid (SA) plays a key role in plant disease resistance and hypersensitive cell death but is also implicated in hardening responses to abiotic stressors. Cadmium (Cd) exposure increased the free SA contents of barley (Hordeum vulgare) roots by a factor of about 2. Cultivation of dry barley caryopses presoaked in SA-containing solution for only 6 h or single transient addition of SA at ...
متن کاملinteractive effects of salicylic acid and silicon on some physiological responses of cadmium-stressed maize seedlings
the impacts of salicylic acid and silicon on some physiological parameters of maize seedlings in the presence ofcadmium (100 μm) were investigated. inhibitory effects of cadmium on seedling growth resulted in reduced shoot and root fresh weight, low percentage of relative water content, low chlorophyll, free proline and soluble sugars contents and a low rate of lipid peroxidation. results indic...
متن کاملPhysiological and biochemical responses of Hypericum perforatum to salt stress and salicylic acid spraying
Salinity is one of the main obstacles to the successful production of agricultural products. Hormonal compounds such as salicylic acid (SA) as plant growth regulators can have different physiological and biochemical effects in plants under salt stress. In present research, the effects of different concentrations of sodium chloride (2, 6 and 10 dS/m) and foliar application of SA (0, 0.25 and ...
متن کاملThe Effects of Foliar Application of Salicylic Acid and Ascorbic Acid on Morpho-Physiological Traits of Pistachio Seedlings under Drought Stress
This study was carried out to investigate the effects of foliar spray of salicylic acid and ascorbic acid on some morpho-physiological traits of Pistacia vera cv. Badami-zarand under drought stress. The experiment was conducted during 2017-2018 in the greenhouse condition, in a factorial randomized complete block design with three replications on pot plants. The soil texture of experim...
متن کاملUptake of inorganic and amino acid nitrogen from soil by Eucalyptus regnans and Eucalyptus pauciflora seedlings.
This study examined whether two species of Eucalyptus can take up the amino acid glycine from soil and compared the uptake rate of glycine with the uptake rates of nitrate and ammonium. Ectomycorrhizal seedlings of two ecologically disparate species were studied: Eucalyptus regnans F. Muell., a fast-growing forest tree from low altitudes; and Eucalyptus pauciflora Sieber ex Spreng., a slow-grow...
