تولید و معرفی ارقام پرمحصول و مقاوم به خشکی در محصولات زراعی یکی از راهکارهای موثری است که در تلفیق با سایر روش‌های مدیریت کم آبی می‌تواند تأثیر این پدیده را به حداقل برساند. تحقیق حاضر با این هدف روی 18 ژنوتیپ برتر آزمایشات مقایسه عملکرد به همراه دو شاهد سرداری و آذر-2 در دو منطقه کرمانشاه (ایستگاه سرارود) و مراغه (ایستگاه مراغه) به‌مدت سه سال زراعی (84-1381) و در شرایط رطوبتی متفاوت (دیم، یک...
Salinity is one of a major abiotic stress, specifically on arid and semi-arid areas that has influenced on crop growth and reduced grain yield. The purpose of present study was identification of agronomic traits related to wheat grain yield variation under control and salinity conditions. In order to produce a population of 272 recombinant inbred lines (RILs), a cross between two bread wheat cu...
The studied volcanic and pluton rocks are located in west of Nir city in the Ardebil Province and south of Sabalan volcano. Volcanic rocks in the studied area are display basaltic to trachy-andesite composition with microlitic porphyry texture. The main minerals of basalt to trachyandesite rocks are plagioclase, pyroxene and olivine. Bordering to volcanic units, pluton of microgabbroic to micro...

the effects of different grazing intensities on the above and underground biomass of twospecies festucaovina l. and alopecurustextilisboiss. in the north sabalan rangelands (in shabil) were investigated. sampling on the light, medium and heavy grazing intensities in the flowering stage (the second half of june 2013) were performed. initially, from a 90-meter transects perpendicular to the slope...
conclusions the data of the study clearly indicated that the eo of s. hortensis has a strong antioxidant, antibacterial, and antifungal activity. results total phenolic content was determined by using folin-ciocalteu reagent (32.65 mg/g), which was presented as gallic acid equivalent in 1 g of sample. ic50 of eo and ascorbic acid in dpph method were respectively 277.9 and 19.34 µg. minimum inhi...
To evaluate cold resistance in wheat in laboratory and to find fast and effective methods of evaluation, nine wheat genotypes were studied in three experiments at the College of Agriculture, University of Tehran, Karaj, Iran. Genotypes consisted of four Iranian cultivars, Sabalan, Boulani, Khalij and Naz one Russian cultivar, Bezostaya and four Iranian accessions, 518, 583, 592 and 1255. In exp...
