The molecular status of nine species of the genus Alburnoides from different river drainages in Iran and additionally by seven species from Europe was assessed. mtDNA COI gene sequences from freshly collected specimens and available NCBI data revealed four major phylogenetic lineages. Based on the results, a distinct taxon from the Cheshmeh Ali (Ali Spring), a Damghan River tributary in the end...

Although microplastics (MPs) are ubiquitous environmental contaminants, little is known about their occurrence and behavior in the terrestrial setting. In this study, MPs have been isolated from soils collected various geomorphological features (yardangs, sand dunes, moving sands, seasonal lakes) of Kavir Lut Deserts on Iranian plateau. The number identified 300 g samples ranged zero (not detec...

Establishment of seedlings at early growth stages of crop plants as one of the most important determinants of high yield is severely affected by soil salinity. Therefore, high germination rate and vigorous early growth under saline soils is preferred. In this study 15 wheat (Triticum aestivum L.) cultivars were used to investigate the effects of three salinity concentrations including 4, 8 and ...

Barley next to wheat is the most important and widely adapted food cereal in the lower parts of Karkhe River Basin. This crop is one of the most salt-tolerant crop species. Varieties of the crop differ considerably in their ability to tolerate salinity. These differences can be used for selecting high yielding varieties under saline conditions. A field experiment was conducted in Dasht-e Azadeg...

  Abstract In most southern provinces of Iran, soil salinity is a growing problem, particularly in irrigated agricultural areas, and has been found to reduce wheat yield, dramatically. To investigate the effect of sodium chloride on two wheat (Triticum aestivum L.) cultivars, four levels of salinity: 0, 4, 8 and 12 dS/m, were employed as a factorial experiment arranged in a randomized complet...

in desert areas high temperature and low precipitation limit growth and development of plants. under this circumstances wind becomes the most important erosion and transportation factor in these areas. there are four great sand masses in the central part of dasht-e-kavir namely rig-e-jen, rig-e-sargardan (shotori or halvan), rig-e-kharturan, and rig-e- chah-e-jam. these great sandy masses show ...
