from the plants nutrition view point, silicon has not been recognized as an essential element but its useful effects on growth and development of many plants have been reported. in order to study the effect of application of different silicon on the yield component of wheat, an experiment was conducted in the city torbat heidarieh located in razavi khorasan province. the experiment was performe...

abstract a hydroponics experiment was conducted to compare effect of fe-deficiency on concentration, uptake, translocation of fe, zn, mn in some plants. a completely randomized block design in triplicates was conducted in research greenhouse. seven plants with different fe-efficiency contained two bread wheat genotypes (triticum aestivium l. cvs. backcross roshan and qods), triticale (x. tritic...

study area is located in west of iran with relatively rough topography. lithologic units in the region belong from jurassic and cretaccous till recent era. the study area of the alvand mountain region is related to the tectonic zone of the sanandaj-sirjan region and the area dominant neo-tectonic regime appears to be compressional-extensional type. one of the identification tools to find out th...

this study was carried out to determine the effect of fermentation, hydrothermal treatment, soda (na2co3), and table salt (nacl) addition on the extent of phytase activity and phytate degradation in three iranian wheat cultivars, namely, mahdavi, ghods, and roshan. the samples were milled to three different extraction rates, i.e. whole, 85%, and 75% flours and three kinds of leavening procedure...

six cultivars of hexaploid wheat (hyrmand, shiraz, pishtaz, marvdasht, mahdavi, roshan ‎‎(susceptible check) and m-79-6) in subplots, and three seed treatments: i1 – seed without ‎treatment; i2- seeds artificially infected with bunt spores in 5/1000 ratio and i3- seeds treated ‎with carboxin thiram fs in main plots of a split plot trial within a rcbd with three ‎replications and 3 locations of ...

in order to study on adaptability and grain yield stability of eight bread wheat cultivars (alvand, alamout, zarrin, navid, azar 2, sabalan, omid and bezostiya), a rcbd experiment was conducted during three cropping seasons (2007-2010) at six locations (sanandaj, gorveh, marivan, divandarreh, saggez and baneh). simple analysis of variance (anova) and combined anova for three years in each locat...

The aim of this review is to check the possibilities and circumstances regarding how create a high-density Persian walnut orchard. Increasing yields, decreasing tree size, limiting juveniles, lowering total costs are most important objectives breeders horticulturists. Reducing size trees can increase yield. Breeding programs in several countries have led production dwarf rootstocks. For example...
