Temperature, humidity and precipitation in an area, are parameters proved influential in the climate of that area, and one should recognize them so that he can determine the climate of that area. Climate changes are of primary importance in climatology, and in recent years, have been of great concern to researchers and even politicians and organizations, for they can play an important role in s...

Expression patterns of four candidate AREB/ABF genes and four DREB/CBF genes were evaluated in leaf and root tissues of five grape varieties ('Qalati', 'Kaj Angoor', 'Sabz Angoor', 'Siahe Zarghan', 'Bidane Safid') with differential response to drought stress. Among the AREB/ABF genes, AREB1 and ABF2 showed up-regulation in response to drought stress in leaf and root tissues of all varieties whi...

thrips tabaci is one of the most important pests causing serioues damages on onion s in iran despite several chemical sprayings. to assess the population density and damage of the thips on onion, improved sefid-e-khomein genotype along with seven other iranian cultivars of onoin were planted in a rcb design with four replications in two separate experiments (sprayed and non-spray ed ) in arak f...

Objective In this study, the levels and antioxidant activities of some secondary metabolites isolated from five pistachio (Pistacia vera) cultivars collected from four different geographical regions of Iran, were studied. Materials and Methods Total phenolic compounds levels were determined by Folin-Ciocalteu method. Total flavonoid content was determined as AlCl3 complex and expressed as mg ...

the influence of water deprivation on potted grape (vitis vinifera l.) was investigated. leaf mass area (lma) and biochemical responses, including chlorophyll, total protein, peroxidase activity, soluble carbohydrates, photosynthesis and stomatal conductance were assessed in leaves of ‘sahani’ and ‘bidane sefid’ grape cultivars subjected to progressive drought (soil water potentials of: -0.2, -...

Artificial recharge can be an effective method to raise the groundwater table and to resolve the groundwater crisis in Sefid dasht plain. The most important step to successful accomplishment of artificial recharge is locating suitable areas for artificial recharge. Hence this research carried out with purpose of determining suitable areas for artificial recharge in Sefid dasht plain. Slope, sur...
