Abstract Effects of water stress on root and leaf growth rates and their relationships with yield under normal and water stress conditions were examined at the Greenhouse and Research Field of Faculty of Agriculture, Kerman University, Iran, using seven maize cultivars including SC-404, SC-704, BC-666, TC-647, DC-370, Jeta and Kordona. During a period of 14 days, water stress at -0.4 MPa was ...
background: diabetes has become the next most widespread disease after cancer. recent studies have found that diabetes and moderate to severe vitamin d defi ciency are associated with reduced bone mineral content; therefore administration of vitamin d may correct these conditions. the purpose of this research is to compare the effect of vitamin d administration on bone to implant contact in dia...
The most desirable approach to improve characteristics such as yield with polygenic inheritance and genotype × environment interaction, is simultaneous selection using selection index based on related traits. This study was conducted Research Farm of Isfahan University of Technology, to compare selection indices for barley yield improvement under nitrogen stress and non stress conditions, usi...

insects with over 30,000 aquatic species are known as very successful arthropods in freshwater habitats. some of them are applied as biological indicators for water quality control, as well as the main food supply for fishes and amphibians. the faunistic studies are the basic step in entomological researches; the current study was carried out emphasizing on the fauna of aquatic insects in karaj...
In order to investigate the limited irrigation impact on physical characteristics of seed in nine sunflower hybrids, three 3-replicate field experiments RCBC were conducted under three irrigation regimes (irrigation after 60, 120 and 180 mm cumulative evaporation from class A evaporation pan, respectively) at the research field of Seed and Plant Improvement Institute in Karaj, Iran. The results...
