the aim of this research is the study of trends in annual precipitation changes in some selected stations located in the sefid rood basin, applying the man-kendall non-parametric technique. the method is one of the most frequently used non-parametric techniques for trend analysis of precipitation on an annual scale. six synoptic stations located in the sefid rood basin were selected for the ana...

  Mahisefid is the most popular fish in Iran with the highest economic value. The analysis of mitochondrial DNA has been extensively used as a marker for population genetic studies and is a powerful tool in studies of gene flow and evolutionary biology. Two hundred ninety four samples were collected from Sefid Rud River (100), Lamir River (98), Shir Rud River (48) and Tajan River (48) during s...

most sweet cherry cultivars are as found as self-incompatible and therefore for commercial fruit production, compatible pollinizers are needed. controlled pollination and microscopic examination of pollen tube growth in the style are two classical methods for determination of compatible and incompatible pollen donor cultivars. this experiment was carried out to explore the compatibility of ‘zar...
