environmental stress, particularly drought stress can play an important role in reducing plant growth especially during the germination stage in arid and semi-arid regions in iran. for cultivation of medicinal plants in arid and semi-arid areas, the assessment of their tolerance is very important. in this research, in order to evaluate the effects of salicylic acid pretreatment on enhancement o...

BACKGROUND Among NSAIDs acetyl salicylic acid remains as a valuable tool because of the variety of benefic prophylactic and therapeutic effects. Nevertheless, the molecular bases for these responses have not been complete understood. We explored the effect of acetyl salicylic acid on the heat shock response. RESULTS Peripheral blood mononuclear cells from rats challenged with acetyl salicylic...

Two iron-regulated compounds have been found in acidified ethyl acetate extracts from culture supernatants of Pseudomonas aeruginosa and Pseudomonas cepacia type-strains. Synthesis of both compounds paralleled iron-deficient growth, and was repressed in the presence of 100 microM-FeCl3. Yields of these substances varied among different strains and attained maximum levels during stationary phase...

The application of short-term stresses or elicitors in seedlings or embryos with high metabolic activity might increase multi-adversity tolerance. Beans seeds cv. IAC-Carioca were exposed to cold shock temperatures (S 7°C 24h) and salicylic acid (SA 0.01 mM 48h) during imbibition to study physiological responses to osmotic stress physiological responses. The seeds were soaked in paper towel imb...

in this research, the effects of thidiazuron pulse treatment and salicylic acid were examined to improve vase life and maintain the quality of alstroemeria ҅modena҆ cut flowers. the experiment was done in a factorial experiment based on rcd with 16 treatments, 3 replications and 48 plots. the flowers were placed in different concentrations of thidiazuron (0, 10, 20, and 50 μm) and salicylic acid ...

topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine csr2, csr4 and csr2xcsr4 crossbreed races of the silkworm, bombyx mori l. the results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoon...

to improve the photo-catalytic degradation of salicylic acid, we reported the fabrication of ordered tio2 nanotube arrays by a simple and effective two-step anodization method and then these tio2 nanotubes treated in a methanol solution under uv light irradiation. the tio2 nanotubes prepared in the two-step anodization process showed better photo-catalytic activity than tio2 nanotubes prepared ...

ABSTRACT Guava is a fruit widely produced in Northeast Brazil, region that has sources of water with high levels salts, making it difficult for irrigated production to expand. Thus, extremely important search techniques allow the management these waters agriculture. objective present study was evaluate photosynthetic pigments, quantum yield photosystem II, and intercellular leakage electrolytes...
