This study was conducted to evaluate the response of Nitraria schoberi under sand burial. Experiment conducted with two years old sapling with four treatments ( control, 33%, 50%, 66% burial and complete burial). Result showed that the highest concentration of proline (29 mg/gfw) observed in 50% and 66% burial treatment. The lowest concentration of proline (16 mg/gfw) observed in control....
Plant tissue culture techniques were used to study the effect of NaCl on tropane alkaloids accumulation and proline content of both Datura metel and Datura stramonium. Callus cultures were established for both Datura species. However, MS medium supplemented with 1mg/l of both BA and NAA was the best for callus production in D. metel, while MS supplemented wit...
abstract the primary purpose of this study was to explore the actual practices and cognitions of two groups of iranian eap teachers, i.e. language teachers and content teachers, with respect to teaching reading-comprehension and vocabulary. to this end, tehran university of medical sciences which authorizes both groups of teachers to teach eap courses was selected as the context of the study s...
Salinity is one of the most important limiting factors for growth and product of plants around the world. Identification of salt tolerant varieties and improvement of plants tolerance are the most effective way to increase its performance. Experiments were conducted in a hydroponic system in order to study the reaction of borage (Borago officinalis L.) to salinity in terms of developmental chan...
Salinity is a main and common stress which decreases the amount of agriculture products and natural plants in many areas of the world. In this study, the effect of salt stress on three varieties of Lotus corniculatus 'Karaj', 'Jolfa', and 'Ardabil' was investigated. Plants were cultured in hydroponic condition with four NaCl treatments (0, 50, 100, 150 mM). The amounts of proline, glycine betai...
Salinity is a complex phenomenon that involves not just an osmotic effect, but also toxic ion effects and nutritional imbalance. In order to evaluate the effects of severity and duration of sodium chloride stress on some biochemical and photosynthesis parameters of tobacco a factorial experiment was conducted using a randomized completely block design with three replication with using a hydropo...
Abstract Dorema ammoniacum is a medicinal plant, with plenty of chemical constituents, which has been used extensively in curing diseases. To study the salt tolerance of Dorema ammoniacum, its seedlings were put under different salinity treatments under hydroponic conditions. Dorema ammoniacum seeds were transferred to cold (4-5 °C) pretreatment for germination for 27 days. The germinated seed...
studying the physiological responses of linseed genotypes to water deficit stress may be helpful in recognizing the linseed resistance mechanisms to the latter stress factors. therefore, a split plot rcbd field experiment was conducted with three replications to explain interrelations of leaf chlorophyll, proline and soluble carbohydrates content and grain yield of six linseed genotypes under t...
the effects of lead on the proline content and dry weight of leaves and roots were investigated in two canola cultivars (brassica napus l.) grown in the hoagland solution. the growth of treated plants was inhibited under lead stress. lead induced differential accumulation of proline in canola grown in solution with the addition of 0, 100 and 200 mgl-1 of pb. hyola308 cultivar showed low biomass...
The objective of this paper was to study the effects of two strains of isolated plant growth-promoting rhizobacteria (PGPR) on physiological and biochemical changes of wheat leaves under salinity conditions. The sterilized seeds were soaked in distilled water (control) and Nutrient Broth liquid medium of Enterobacter cloacae and Bacillus cereus (inoculated treatment) for 2 hours. After 10 days ...
