Silicon is as an essential element for crops and an important food source for the growth of rice plant. If no adequate replacement for this element, plants are faced with a shortage of silicon causing serious eating disorder and instability in plant resistance to pests. This research was done to investigate the effect of silicon on growth, yield and tolerance to rice stem borer in Tarom Hashemi...

Rice is a second important crop at Iran and its cooking and eating quality plays important role for consumers. In order to improve yield and quality, a set of crosses among Amol3 and Sepidrood made with Dom­­­Siah Mashhad and Sange Jo. The F1 was back crossed with local varieties as donor parents for two successive generations (BC2) and then selfed upto five generations (BC2F5). 13 promising li...

Arsenic contamination in soils often leads to groundwater contamination and arsenic toxicity in plants, humans and animals. Plant hormones play a quantitative and qualitative role in the coordination of growth and yield in plants. In this research the effects of gibberellin and sodium arsenate in different genotypes of rice were studied. The work has been conducted as a factorial experiment bas...

in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...

In order to identify QTLs controlling agronomically traits, landrace Tarom and rice Tarom mutant were crossed. SSR, ISSR, iPBS and IRAP markers were amplified in 250 F2 individuals to prepare the linkage map. Number of tillers, 100 grain weight, number of filled grains, number of unfilled grains, plant height, panicle length, number of branches, stem diameter, grain length, grain width, grain s...

regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
