Safflower having oil with high unsaturated fatty acids is a very valuable plant. However the sensitivity of safflower to some pests as safflower fly (Acanthiophilus helianthi), particularly in drought stress conditions has limited its production. In order to evaluate the effect of drought stress on population density and damage of important safflower pests, especially safflower fly, an experime...

In order to investigate the effect of dehydration stress and planting date on some physiological indices and growth of Cymbopogon citratus, a field experiment in the form of a split plot in a randomized complete block design with 3 replications, including 3 levels of different irrigation (100% full irrigation as a control, 75 and 50% full irrigation) and 3 levels of planting date including 20 M...

In order to evaluate the response of 20 lines and cultivars of soybean to water deficit stress, an experiment was conducted at Agricultural Research Station of Gorgan in 2011 and 2012. For this Purpose, 2 separate experiments was conducted, each one in randomized complete block design, with 3 replications. In first experiment, all soybean genotypes were irrigated based on 50 mm evaporation from...

In this research, the effects of 5-aminolevulinic acid, as a key precursor in the biosynthesis of porphyrin compounds such as chlorophyll, in mitigating salt stress were studied in Lycopersicum esculentum mill. Salinity at three levels (0, 50 and 75 mM NaCl) and ALA treatment at three levels (0, 1 and 2 mM) were applied on plants of this species. Both levels of salt (50 and 75 mM) reduced shoot...

in the name of allah , the compassionate the merciful abstract shath ( blasphemic utterace made during spiritual ) is a complicated concept that deserves reflection in gnosticism and sufism ( mysticism ) and estem and westem scholars have alwaya paid attention to it. although principal essence of gnostic belief is the holy divine law ,gnosticism has pure and unique thoughts . by glancing at t...

Drought stress represents the most limiting factors for agricultural productivity in arid and semiarid region of the world. This research was conducted to evaluate the effect of drought stress on root morphological attributes and dry matter yield in tall fescue Festuca arundinacea. Twelve genotypes were assessed under three levels of moisture regime (non-stress, moderate drought stress and seve...

in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...
