  For identifying osmoreguulation (or) differences in bread wheat genotypes, three experiments by using of randomized complete blocks design with five replications were carried out separately on 6 genotypes (Tabasi, Alvand, Shahi, Sabalan, Sardary and Roshan) under normal, drought and salinity stresses. At earring stage, in order to studying osmotic stress on pollen grains, treatments of 30% PEG (control) and 50% PEG with 10 mM KCl (osmotic stress) were applied. All pollen grains of genotypes were been swollen at control treatment, but under osmotic stress except of Roshan pollen grain (due to accumulation of K+ ion) was been shrinkage. Orthogonal analysis of variance showed significant differences for traits of grain yield and its components, soluble sugars, Na+, K+ accumulations. Under stress Roshan genotype had high accumulation of soluble sugars and K+. Increasing of grain yield due to or gene at Roshan than other genotypes under drought and salinity stresses were, respectively 18.14 and 38.80%. So, under drought and salinity stresses, identification of or allele and selection based on it in wheat breeding programs are strongly recommended.

  A way of estimation agriculture development and product stability agricultural location is using of energy flow method. In this consideration, energy flow at agricultural ecosystems of 2 grape in cities from west Azerbaijan province was compared. The related data of inputs and outputs for evaluation of energy efficiency in these gardens are become equivalent value of input and output energy efficiency. Energy value of used factors and input in grape gardens of Urmia and sardasht were 6417773 and 862570 k cal ha 1, respectively and output (production) energy value of the gardens were 25632600 and 10123800 k cal ha 1, respectively. Energy efficiency values (output: input ration) were 3.99 and 11.7, respectively. Data showed in grape gardens of Urmia the most use of energy were nitrogen fertilized usage and irrigation. In grape gardens of sardasht the most use of energy was nitrogen fertilized. In general, because of the climate conditions, topography and society culture in these regions the difference in energy efficiency of these gardens almost was reasonable. The number of inputs increases; effect increases any one of input decrease. Grape garden system of sardasht hasnít any contamination and agricultural systems because of much annual rainfall in this region are dry farming. Therefor, costs of irrigation and poisoning are deleted but inordinately poisoning of Urmia gardens result in contamination and transformed these ecosystems.

  This experiment with nine genotypes consist of 8 sunflower hybrid along with Record cultivar were sown in a randomized complete block design with 4 replication at the experiment farm of uremia university in 2004. Twelve quantitative traits (Days to 50% flowering, days to physiological maturity, plant height, number of leaves per plant, head diameter, number of filled seed per head, 1000 seed weight, kernel percentage, unfilled seed percentage, oil percentage, seed tiled, oil yield) were evaluated and measured. Among evaluated traits, number of filled seeds/head (0.754**) 1000 seed weight (0.732**) and head diameter (0.723**) had highest positive and significant correlation with seed yield and seed yield (0.843**) had highest positive and significant correlation with oil yield. Stepwise regression for seed and oil yield indicated that five traits including number of filled seed/head, 1000 seed weight, head diameter, oil percentage. Regarding the direct and indirect effects of each effective traits in oil and seed yield, it seems that screening with emphasis of the number of filled seeds/head, 1000 seed weight and head diameter could be effected on maximum.
