Tomato (Lycpoersicum esculemtum) belongs to the Solanaceae potato family and is an important crop plant. It is relatively resistant to salinity, but in the saline environment growth and production of the plant significantly reduces. On the other hand, the presence of mycorrhiza fungus can improve the adverse effects of salinity. A factorial experiment in a completely randomized design with thre...

abstract to assay the effect of acetylsalicylic acid pretreatment on enhancement of yield and yield components of barley (reihan-03) under water stress condition, an experiment was conducted as a spilt-plot arrangement based on randomized complete block design with four replications at the research field of shahid bahonar university of kerman, iran, in 2012-2013. irrigation condition was arrang...

The effect of copperchloride (CuCl2) on the level of chlorophyll (a+b), proline, protein and abscisic acid in sunflower (Helianthus annuus L.) seedlings were investigated Control and copper treated (0.4, 0.5 and 0.6 mM) seedlings were grown for ten days in Hoagland solution. Abscisic acid content was determined in root, shoot and leaf tissues of seedlings by HPLC. Copper stress caused significa...

Aqueous solutions of the bioprotectant proline are simulated for solute molar fractions ranging from 2.0 · 10 3 to 2.3 · 10 . Statistical analyses show that proline affects the water structure more strongly than glycine betaine and trimethylamine-N-oxide, two of the most effective bioprotectants widely diffuse in nature, and as strongly as tert-butyl alcohol, a protein denaturant which at high ...

Salinity is one of the major environmental stresses that limit plant growth and productivity. Glasswort (Salicornia herbacea L.) is one of the native halophytic plants of Iran that widely spread in salt areas. The purpose of this study was to determine the physiological and growth responses of S. herbacea to salinity stress. Plastic pods (15 cm diameter, 20 cm height) with the Silica sand bed w...

soil salinity threat for agricultural ecosystems in many parts of iran, and negatively affects crop production. in order to examine salinity tolerance of kochia a series of experiments were conducted in crd with four replications, seven levels of salinity (0, 10, 20, 30, 40, 50 and 60 ds.m-1), two growth stages (planting and early seedling) and interval irrigation. result showed that decrease o...
