The research presented here highlights the use of a simple incubation procedure to evaluate the relative salt tolerance of currently available rice cultivars over a wide range of salt concentrations. Rice seeds were subjected to a series of salt solutions from 0 to 20 micromhos/cm, and the ability of each cultivar to germinate and develop to the S3 growth stage was evaluated. Germination values...
In order to evaluate salt tolerance in seedling stage, seeds of 11 hybrid and new varieties of cotton, compared to commercial cultivars of Golestan as control were planted in pot. Factorial experiment in a completely randomized design with three replications was conducted at the Cotton Research Institute of Iran in 2014. The first factor was salinity levels and the second factor was 12 genotype...
background: the iodine deficiency elimination program that began two decades ago resulted in iran becoming an iodine deficiency disorders free country in the middle east region. the present study was performed to evaluate the adequacy of iodine supplementation after 17 years of universal salt iodization in fars province. methods: in a cross-sectional study, 1200 schoolchildren (480 girls and ...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
Salinity is an important environmental factor that limits plant growth and production. Grape is classified as salt sensitive plants. The object of this study was to evaluate effects of salinity on membrane lipid peroxidation, antioxidant components, and antioxidative enzymes activity in ten grape genotypes native to the regions around Urmia Salt Lake.Malondialdehyde content and protective enzym...
In order to evaluate the effects of salt stress and putrescine on some morphological and biochemical traits and pigment content of pot marigold plant, an experiment was conducted under greenhouse conditions based on completely randomized design, using four levels of sodium chloride (1, 3, 6 and 9 dS/m) and three levels of putrescine (0, 1 and 2 mM). Sodium chloride was applied on the soil, whil...
in order to evaluate salt (nacl) tolerance in alfalfa (medicago sativa l.) half-sib families, a factorial experiment on the basis of completely randomized design, with 20-25 individuals in pot (replicates) was carried out under field conditions at the research station of university of tabriz. electrophoretic analyses were performed by using 7.5% slab polyacrylamide gels. two antioxidant enzymes...
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...
Crop performance is severely affected by high salt concentrations in soils. To engineer more salt-tolerant plants it is crucial to unravel the key components of the plant salt-tolerance network. Here we review our understanding of the core salt-tolerance mechanisms in plants. Recent studies have shown that stress sensing and signaling components can play important roles in regulating the plant ...
Salt cedar is widely spread out in most part of the country but there is lack of information about its symbiosis with arbuscular mycorrhizal fungi. Then, the main objective of this study was to evaluate the symbiosis of AMF with salt cedar and its affectability by distance from river and soil physiochemical properties. For this purpose, riparian Maroon forest width was divided to three location...
