concerning limitation of water resources, determination of the least water that can lead to the maximum yield is of great importance in crop production. in order to evaluate effects of deficit irrigation on grain yield and water use efficiency of some wheat )triticum aestivum) cultivars under different climatic conditions, two similar field experiments were conducted in 2004 in agricultural res...
chilling is an important environmental stress that influences the yield and quality of many agricultural crops. different plants use different systems to endure this stress and minimize its effects. one of these systems is enzymatic reaction. to find out more about responses of different grapevine species and cultivars to the low temperature conditions, their enzymatic changes were evaluated in...
For evaluation of spring wheat cultivars using drought resistance indices, two separately experiments were done in split plot basis of Random Complete Block Design with four replications. This research was done with complete irrigation (control) and drought stress that start before and after of booting stage in research farm of Agriculture Faculty, University of Tabriz. Basis grain yield in irr...
damage caused by freezing can be the result of differences in cellular processes, including changes in membrane properties, interactions between macromolecular and enzymatic reactions. in this experiment, total soluble solids (tss) and relative water content of the reproductive buds of cultivars “j. h. hale”, “elberta,” “redhaven, ” “sorkh sefid mashhad” and “amsden” peaches, along with nectari...
For evaluation of the reaction twenty of spring wheat cultivars under complete irrigation (control) and drought stress condition starting before booting stage, an experiment was conducted in split plot basis of Randomized Complete Block Design with 4 replications in two cropping years (2010-2011 and 2011-2012) in research farm of Agriculture Faculty, University of Tabriz. The results of varianc...
In order to study the effect of terminal drought stress on yield and yield components and some physiological traits of wheat genotypes, a field experiment was conducted at the Research Farm of Agricultural College of Shiraz University during 2010-11 growing season in a split plot arrangement based on randomized complete block design with three replications. Main plots were assigned to irrigatio...
In this study, the optimum irrigation depths for corn grain production under different conditions, i.e. maximum grain yield production and maximum benefit under limited land and water conditions, were determined under sprinkler irrigation in Bajgah (15 km. north of Shiraz). The results showed that, the optimum depth of irrigation for maximum grain yield production was 77.0 cm. Because of low pr...
Drought is one of the most destructive abiotic stresses worldwide that affects growth, development and final yield of crops. Reactions of thirteen rainfed spring 2-row barley genotypes and cultivars of cold areas of Iran to water stress were evaluated based on phenological, physiological and morphological traits. The experiment was carried out as factorial experiment based on a randomized com...
Effect of salinity on pollen viability, germination and yield was investigated on 8 canola cvs. Dunkled, Canola-III, Oscar, Ganyou-5, Ganyou-2, Rainbow, Abasin-95 and Westar. Plants were irrigated with non saline, 0.2% (E.C 2.5 dS.m). 0.4% (E.C 4.5 dS.m) and 0.6% (6.5 dS.m) of sea salt concentrations. Plant growth on vegetative as well as reproductive phases was proportionately inhibited with r...
