in order to investigate the tolerance of wild barley (hordeum spontaneum), wild oat (avena ludoviciana) and different wheat (triticum aestivum) cultivars to metribuzin (sencore®), a completely randomized design experiment was conducted in ferdowsi university of mashhad. the treatment were replicated three times and included wheat cultivars (atila, chamran, niknejad, dorum, gaskojen), weed speci...

The aim of present study was to compare levels of genetic polymorphism between offspring of  wild , farmed and mix of them of Roach (Rurilus rutilus caspicus) using five microsatellite loci  (CA1, CA7, CypG27, Lid1, Rru4). Genetic diversity was investigated by studying samples collected from three population, 90 fish, thirty specimen form each population. All samples fixed in ethanol 96% until ...

A greenhouse experiment was conducted to evaluate the competitive effects of different densities of wild mustardas against rapeseed. The experiment was performed in a randomized complete block design with four replicationsusing replacement series in which wild mustard and rapeseed were respectively planted in different ratios of 4:0, 3:1,2:2, 1:3 and 0:4 plants per pot. Results indicated that t...

Climate change is one of the most important issues in the global social, political and economic agenda, yet it has taken a while to be prioritized. This is partly because climatic change was communicated as a scientific problem which was originally complex, confusing and at times contested scientific information which resulted to a slow public and political awareness. Thus, climate change comme...

Spatial pattern of trees in forests reveals how trees interact with each other and their environment. Spatial structure of trees in forest ecosystems is affected by environmental heterogeneity that leads to their heterogeneous distribution. This study was aimed to investigate the appropriate methods to analyze spatial pattern of heterogeneous wild pistachio woodlands in Zagros, Iran. A 40-ha pu...
