sulforaphane is a strong anticarsenogen compound which is produced in broccoli. it seems salt stress improves sulforaphane production via systemic acquired resistance. to obtain suitable salt concentration and for having more content of sulforaphane with controlling germination percentage, nacl in 5 levels 0, 50, 100, 150, 200 mm (0, 4.53, 9.125, 13.68, 18.25 ds/m ) and salicylic acid in 3 leve...

this experiment was carried out as factorial based on randomized complete block design with four replications in 2011-2012 growing season. the experimental factors were selenium in four levels 0, 6, 12 and 18 g ha-1 and salicylic acid in three levels 0, 100 and 200 mg l-1. results showed that foliar application of selenium at rate of 12 and 18 g ha-1 decreased ion leakage by 11.6 and 18.8% comp...

AIM To examine sera for the presence of salicylic acid and 2,3- and 2,5-dihydroxybenzoic acids (2,3- and 2,5-DHBA), in individuals not taking salicylate drugs. METHODS Extracts of acidified serum samples were analysed by high performance liquid chromatography with electro-chemical detection. The chromatographic conditions were altered, and the retention times of the unknown compounds compared...

In this study, the role of salicylic acid pre-treatment (0.01, 0.1 mM was investigated)in inducing salt tolerance in sweet basil. Results showed germination percentage, length of shoot and root, fresh and dry weight of leaf, and photosynthetic pigments were decreased in response to high salinity but the lipid peroxidation, coefficient allometry, and soluble sugars increased. In plants pre-treat...

Plant hormones play pivotal roles as signals of plant-pathogen interactions. Here, we report that exogenous application of salicylic acid (SA), jasmonic acid (JA), ethephon (ETH), and abscisic acid (ABA) can reduce Turnip crinkle virus (TCV) accumulation in systemic leaves of Arabidopsis thaliana during early infection. SA and ABA are more efficient and confer a longer-lasting resistance agains...

Salicylic acid inhibited ethylene formation from ACC in self-buffered (pH 3.8) pear (Pyrus communis) cell suspension cultures with a K(1) (app) of about 10 micromolar after 1 to 3 hours incubation. Inhibition appeared noncompetitive. Among 22 related phenolic compounds tested, only acetylsalicylic acid showed similar levels of inhibition. Inhibition by salicylic acid was inversely dependent on ...

We analysed effects of abscisic acid (ABA, a negative regulatory hormone), alone and in combination with positive or neutral hormones, including salicylic acid (SA), on rice growth and expression of cell cycle-related genes. ABA significantly inhibited shoot growth and induced expression of OsKRP4, OsKRP5, and OsKRP6. A yeast two-hybrid assay showed that OsKRP4, OsKRP5, and OsKRP6 interacted wi...

soil and water sources salinity are important constrains which threat the sustainable agriculture production in iran. in order to evaluate the effect of different antioxidants and salinity levels on germination and seedling properties of two medicinal species (cnicus benedictus l.), and (cichorium intybus l.), an experiment was conducted using a factorial based on completely randomized design w...
