in order to study the effects of different salinity levels on turnip (brassica rapa l.), an investigation was conducted at yasouj university, iran, in 2010. the effects of four salinity levels including 1.92, 9.87, 19.6 and 21.94 ds m-1 (20:1 ratio of nacl: cacl2 in hoagland solution) on germination, vegetative and maturity stages of turnip (baherghan landrace) were investigated. the results re...

The effects of exogenous abscisic acid (ABA) and its two agonists, Sulfacetamide (Sa) and Sulfasalazine (SS) on tolerance of tomato (Lycopersicon esculentum Mill. Cv. Super chief) under drought stress were studied. Eight-week plants were treated with ABA (25 and 50 mg/L), Sulfacetamide (Sa) (25, 50 and 100 mg/L) and Sulfasalazine (SS) (25, 50 and 100 mg/L). Solutions were sprayed daily and samp...

Although inter-variety variability for salt tolerance has been reported in bread wheat plants, little information is available on the genetic control of ion contents and biomass yield under saline conditions. A diallel cross, including reciprocals of two salt tolerant, two moderately tolerant and two sensitive Iranian and exotic bread wheat varieties, was analyzed to investigate the inheritance...

background: the aim of present study was to determine the influence of stress management on affective control and distress tolerance in mothers of children with sensory-motor disabilities. methods: this current study was a study with pretest-posttest and treatment group. the thirty mothers of children with sensory-motor disabilities were selected from sensory-motor disabilities center in qum by...

using medicinal plants as drug or spice in food have significantly increased in recent decades. also, production of this plants restricted by drought stress. therefor the aim of this was investigation of drought stress effect on fruit and essential oil yield of different endemic coriander genotypes. in this regard, 14 coriander genotypes subjected to two levels of water treatments in two separa...

development of a green belt with suitable plant species around the source of emission can mitigate the atmospheric contamination. selection of such plant species are required to combat air pollution based on their tolerance level. present study was undertaken to evaluate the tolerance level of higher plants in east of esfahan city, iran, during 2011 in terms of assessing air pollution tolerance...

Continuous desertification of arable lands mandates use of low quality/ saline water for irrigation, especially in regions experiencing water shortage. Using low quality/ saline water for irrigation imposes more stress on plants that are already under stress in these regions. Thus, a logical solution will be to find a salt/ drought-tolerant plant species that will survive/sustain under such str...
