effects of seed priming by salicylic acid on yield and yield components of cowpea (vigna unguiculata) cultivar “parastou” were investigated under water deficit conditions. experiment was carried out as a split block design with three replications in 2008-2009 at research station of zanjan university. factors included drought stress as main factor with three levels (normal irrigation, applicatio...

cold stress is considered as a restricting factor in plant production. recently, many different compounds were applied to minimize the harmful effects of stress. in this study, the effects of foliar application of salicylic acid was studied on some biochemical properties of two different cold resistant canola cultivars. salicylic acid was sprayed at four concentrations (0, 100, 200 and 400 µm) ...

the effect of hot water treatments [45°c for five minutes, 55°c for 25 seconds and non-treated(control)], salicylic acid in three levels (0, 1 and 2 mm) and calcium chloride in two levels (2% and 4%) on quantitative and qualitative parameters and storage life of pomegranate cv. meykhosh were investigated. experiment was conducted as a factorial based on completely randomized design with three r...

Acetylsalicylic acid (aspirin) is a common nonsteroidal anti-inflammatory drug used for treatment of pain and arthritis. In the body, acetylsalicylic acid is rapidly deacetylated to form salicylic acid. Both compounds have been proposed as anti-inflammatory agents. Major metabolites of salicylic acid are its acyl and phenolic glucuronide conjugates. Formation of these conjugates, catalyzed by U...

Temperature changes occur in nature faster than other stressors. Plants due to inability to move and change their position, are exposed to extensive variations in daily or seasonal temperature, and therefore, should quickly and effectively adapt to temperature stress. In order to study the effects of heat stress on physiological traits of forage maize hybrids, a factorial split plot experiment ...

Salicylic acid plays a critical role in activating plant defence responses after pathogen attack. Salicylic acid methyltransferase (SAMT) modulates the level of salicylic acid by converting salicylic acid to methyl salicylate. Here, we report that a SAMT gene from soybean (GmSAMT1) plays a role in soybean defence against soybean cyst nematode (Heterodera glycines Ichinohe, SCN). GmSAMT1 was ide...

S. rebaudiana produces steviol glycosides including stevioside and rebaudioside A that are valuable as low calorie sweeteners. The objective of this study was to investigate the effects of salicylic acid elicitation and sampling times on the improvment of stevioside and rebaudioside A production and KA13H, UGT74G1 and UGT76G1 genes expression. The results showed that the addition of different c...
