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...

Salinity causes significant agricultural losses in many areas the world. Plant growth promoting bacteria (PGPB) are a promising solution to enhance plant and productivity under such stress conditions by different mechanisms, mainly phosphorous solubilization. This study aims improve wheat seedling salt halotolerant phosphorous-solubilizing bacterial strain. Soil sample was collected south of Al...

to investigate the influence of salinity and calcium (ca) on some properties of plantago ovata, a pot factorialexperiment based on randomized complete block design with three replicates was conducted in jiroft, south of kermanprovince, iran. three salinity levels of 0, 100 and 200 mm nacl and ca levels of 0, 5 and 10 mm calcium nitrate wereapplied as the first and second factors, respectively. ...

Paclobutrazol (PBZ) is one of the most important triazole compounds. This compound increases plant tolerance to environmental stresses. A study aimed to investigate the effects of PBZ on morphological and biochemical traits of euonymus (Euonymus japonicas) exposed to NaCl stress. Plants were treated with three levels of PBZ (0, 500 and 1000 mg L-1) and four levels of NaCl (0...

The purpose of the work was to assess the combined effect of drought and salinity (50, 100, 200 mМ NaCl) on the mesoand ultrastructure of mesophyll cells of wheat seedlings. Stress development was estimated by a decrease in the relative water content (RWC) and CO2-dependent O2 evolution (An) in leaves. The decrease in the RWC and in An occurred rapidly in the absence of salt in the substrate an...

The effects of salt stress on growth and some physiological parameters of halophytic plant, Leptochloa fusca L. Kunth, were investigated. The seedlings were irrigated with half-strength Hoagland solution and then treated with different concentrations of NaCl (0, 100, 300, 500 and 700 mM) for 15 days. The fresh and dry weights of both root and shoot were unchanged at 100 mM NaCl and decreased at...

in order to evaluate the effect of piriformospora indica fungi inoculation on antioxidant systems and photosynthetic pigments of stevia under salt stress, an experiment was conducted in a factorial based completely randomized design with four replications under in vitro culture conditions. factors include salinity at six levels (0, 50, 100, 150, 200 and 250 mm of nacl) and inoculation of mycorr...

turmeric ( curcuma longa l.) is a perennial rhizomatous plant from the family of zingibraceae, native in south asia. the main components of turmeric are curcuminoids and essential oil which are responsible for turmeric characteristic such as odor and taste. due to the large areas of saline land in iran and less information related to cultivation of turmeric, in this research, the effect of sali...

objective: salt stress is a world-wide problem and soil salinity is common in arid and semi-arid regions. this study was undertaken to investigate salt tolerance in salsola orientalis in laboratory and natural conditions and recognize the mechanisms that allow it to tolerate these conditions. methods: this study had two parts of greenhouse and natural habitats. the treatment solutions for salin...
