Abstract: Wheat grain yield is reduced by post-anthesis drought stress conditions in most wheat growing farmlands of Iran. To evaluate the effect of post-anthesis-withholding irrigation on yield, yield components and canopy temperature of wheat cultivars, a field experiment was conducted as split plot in a completely randomized block design with four replications at experimental farm of coll...
investigation of physiological responses to water deficit in sesame (sesamum indicum l.) genotypes can help to identify effective mechanisms of plant resistance to stress. therefore, chlorophyll content, proline, soluble carbohydrates, net photosynthesis rate, stomatal conductance, maximum quantum efficiency (fv/fm), plant height and shoot dry weight in a complete block factorial pot experiment...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
The effect of water deficit on carbohydrate status and enzymes of carbohydrate metabolism (alpha and beta amylases, sucrose phosphate synthase, sucrose synthase, acid and alkaline invertases) in wheat (Triticum aestivum L.) was investigated in the seedlings of drought-sensitive (PBW 343) and drought-tolerant (C 306) cultivars. The water deficit was induced by adding 6% mannitol (water potential...
Deficit irrigation is a common approach in water-scarce regions to balance productivity and water use, whereas drought stress still occurs various extents, leading reduced physiological performance decrease yield. Therefore, seeking rapid reliable method identify wheat varieties with resistance can help reduce yield loss under deficit. In this study, we compared ten three deficit systems (W0, n...
In order to study the effect of the superabsorbent polymer and manure fertilizer on the baking characteristics of wheat cultivars under different water deficit conditions, an experiment was carried out in a factorial layout based on a randomized complete block design in three replications at Agricultural Research Center, West-Azerbaijan (Saatlo station) during 2017-2018 growing seasons. The fac...
Due to the climate change situation, water deficit stress is becoming one of main factors that threatens agricultural sector in semi-arid zones. Thus, it extremely important provide efficient tools monitoring and early detection. To do so, a set Synthetic Aperture Radar (SAR) backscattering interferometric SAR (InSAR) Sentinel-1 data, covering period from January June 2016, are considered over ...
