aim and background: the purpose of this study was to investigate the relationship between cognitive intelligence and ambiguity tolerance with entrepreneurship of west azarbayjan payam noor university students, iran. methods and materials: this cross-sectional correlational research was conducted during 2010-2011 academic years. 1122 student (672 female and 450 male) were selected using stratifi...
Drought is the most significant constraint for crop production in arid and semi-arid regions. In order to assess drought tolerance in fifteen rapeseed (Brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of College of Agriculture, Shiraz University, Shiraz, Iran during 2009-2010 growing season. The cultivars were...
In order to study tolerance of durum wheat (Triticum durum) lines to drought stress and also evaluating stress tolerance indices, an experiment based on randomized complete block design with four replications was conducted under two rain fed and supplementary irrigation conditions at Gachsaran station during 2011-2012 cropping season using 20 durum wheat lines. Results of combined analysis of v...
Increasing the yield of wheat (Triticum aestivum) requires choosing resistant and compatible cultivars to different climatic conditions. In order to study the effects of salinity and drought stress on grain yield, Study of stress tolerance indices and identification of tolerant genotypes to salt and drought stress, 20 different Wheat (Triticum aestivum) genotypes were assessed in a Randomized ...
Background: Recent studies suggest that normobaric hyperoxia (HO) results in ischemic tolerance to reduce ischemia brain injury. In this research, attempts were made to assess threshold of ischemic tolerance induced by normobaric hyperoxia in rat stroke model. Materials and methods: Rats were divided into two ...
winter sown chickpeas produce more yields in comparison with spring type. this function is hampered by the sensitivity of the crop to low temperature. in order to study and identify high yielding and cold tolerant chickpea (cicer arietinum l.) lines, 65 entries along with one susceptible check variety namely ilc533 were evaluated in a randomized complete block design (rcbd) with two replication...
pretreatment of adults of iraq strain of afhstephenst with a sub-letlial dose of pcrmethrin resulted in a 65% enliancemenl of tolerance to this insecticide. similarly, pre-exposure of dub-lpr larvae to a sub-lethal dose of pcrmethrin resulted in increased tolerance to pcrmethrin. for the sensitive ind-s strain, the inductive effect was smaller. tiie results of bioassays of resistant and suscept...
drought is the most significant constraint for crop production in arid and semi-arid regions. in order to assess drought tolerance in fifteen rapeseed (brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of college of agriculture, shiraz university, shiraz, iran during 2009-2010 growing season. the cultivars were arranged...
frost tolerance of winter wheat depends primarily on a strong vernalization requirement, delaying the transition to reproductive phase. the responses of four bread wheat cultivars (triticum aestivum l.) to low-temperatures were examined in controlled environment and field conditions. prolonged cold treatment accelerated the transition to reproductive development in winter wheats (cv. norstar an...
