To determine the mechanism(s) by which interleukin-I (IL-I) promotes granulopoiesis in vivo, we examined the effect of in vivo administration of IL-la on colony-stimulating factor (CSF) receptor expression on bone marrow cells (BMCs) and whether this directly correlated with progenitor cell responsiveness. Administration of IL-la to mice induced the upregulation of both granulocyte-macrophage-C...

sugar beet cultivation is of great importance in isfahan province. powdery mildew is a major limiting factor to sugar beet. to evaluate powdery mildew status in sugar beet fields, samples were collected from main sugar beet growing areas including, isfahan, semirom, farydan and komsheche during 2009-10. in order to determine the disease severity, in each region, samples were taken at six growth...

Europe has been much more cautious about the introduction of genetically modified (GM) crops than many other countries in the world. But this year it has granted permission to grow a genetically modified potato and also to allow into the market three types of GM maize. The potato, called Amflora and developed by the company BASF in Ludwigshafen, Germany, has been the first GM crop to be approve...

BACKGROUND: Mineral nutrition is one of the most important factors affecting plant growth and productivity, also growth analysis is a way to assess what events occurs during plant growth. OBJECTIVES: The goals of this study were to investigate the effect of different level of nitrogen fertilizer and zinc sulfate on growth indices of Green bean. <str...

background and objectives: sugar beet (beta vulgaris l.) is the major crop in khorasan province which is mainly grown in spring. however, autumn sowing has a lot of advantages including lower crop water requirement and higher water use efficiency. accordingly, this research was performed to compare the yield of storage organ in spring and autumn-sown sugar beet and determine the most appropriat...

Root influx parameters (Vmax and Km) of wheat (Triticum aestivum var. HD-2285) were determined at different stages of crop growth, viz. CRIS-Crown Root Initiation Stage, MTS-Maximum Tillering Stage, FLS-Flag Leaf Stage and DFS-Dough Formation Stage. Wheat was grown in sand medium with Hoagland nutrient solution (all nutrients except potassium). Plants were taken out from sand culture at 22, 41,...

Vermiwash (VW), a liquid extract obtained from vermicomposting beds, is used as an organic fertilizer for crop plants. The current study investigated the effect of a vermiwash foliar spray on the response of bhut jolokia (Capsicum assamicum) exposed to two different arbuscular mycorrhizal fungi (AMF: Rhizophagus irregularis, RI and G. mosseae, GM) in acidic soil under naturally ventilated green...

in order to evaluate cardinal temperatures and optimum thermal range of germination of three medicinal plants including ajowan, fennel and dill an experiment was conducted in a completely randomized design with three replications. temperatures considered for this study were: 5, 10, 15, 20, 25, 30 and 35 ?c. results indicated that temperature affected germination rate and percentage of these cro...

to evaluate the effects of on-farm seed priming treatments and sowing dates on rate and percentage of seedling emergence, biological yield and some physiological indices of corn hybrid (sc. 260) an experiment was conducted in hamedan, iran in 2010. a split plot in a randomized complete block design with three replications was conducted. main plots include three sowing dates (early, on-time and ...

This research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. This experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of Chenran Township. The results ...
