بهمنظور بررسی اثر تنش خشکی پس از گردهافشانی بر صفات زراعی و برخی از ویژگیهای فیزیولوژیکی برگ پرچم و سنبله ژنوتیپ‌های مختلف گندم آزمایشی بهصورت فاکتوریل در قالب طرح پایه بلوکهای کامل تصادفی با سه تکرار اجرا گردید. دو سطح آبیاری شامل شاهد (آبیاری در تمام مراحل رشدی براساس شرایط کشت آبی) و تنش خشکی (قطع آبیاری پس از گردهافشانی تا پایان دوره رشد) به‌عنوان فاکتور اول و ژنوتیپ‌های مختلف گندم (S...
In this study, we obtained two-dimensional tomography maps of the Rayleigh wave group velocity for the northwest part of the Iranian Plateau in order to investigate the structure of the crust and the uppermost mantle of NW Iran. To do this, the local earthquake data during the period 2006-2013, recorded by the 10 broadband stations of the Iranian seismic network (INSN) were used. After the prel...
this research was conducted to investigate genotyp×environment interaction for grain yield of ten wheat cultivars in 8 environments (combinations of two nitrogen fertilizer treatment and four irrigation regimes). analysis of additive main effects (analysis of variance) and multiplicative interaction effects (principal component analysis) revealed that the effects of genotype, environment and ge...
in recent years, the russian wheat aphid, has been included worldwidely in the list of the important pests of cereals, particularly wheat plants. in addition to direct serious damage, the aphid is the main vector of barley yellow dwarf, barley mosaic, and sugarcane mosaic viruses. the pest was reported from east azarbaidjan province (iran) a few years ago and it is now widespread in tabriz,...
Abstract Background and Objective: It has been proved that plant essential oils have antimicrobial effects. Stachys Lavandulifolia Vachl is a medicinal plant growing wild in many parts of Iran, and is used as a brewed drink to treat some diseases. Material and Methods: Aerial parts of Stachys lavandulifolia Vachl at flowering were collected from the Sabalan mountainous &nbs...
Grazing intensity should follow the management roles to prevent the soil compaction. Soil compaction decreases plant root penetration so that at 2 MPa the root extension and above ground biomass will stop. In this research, digital penetrometer was used to assessment the soil compaction level in Sabalan region in Ardabil province caused by livestock. Grazing intensity and distance from villa...
Today, due to industrial advances and the expansion of urban environments, it is essential to create ecoparks as places that can provide natural environments for human. The current study performed a comparative ecopark site selection across Ardabil, Meshkinshahr, Sarein, Nir and Namin, using multi-criteria analysis models. To achieve the research objective, four criteria and 15 sub-criteria wer...
Line TO/CAL/3/7C//Bb/CNO/5/CAL//CNO/Sn64/4/CNO//Bad/DAR/3/KL/6/Sabalan was received from ICARDA under International Winter Wheat Improvement in 1999-2000 cropping season. Based on its favorable agronomic characteristics, it was selected for further evaluations in advanced and elite yield trials in main research stations of Dryland Agricultural Research Institute (DARI) and on farm yield trials ...
a hybrid hydro/wind/photovoltaic base on hydrogen storage system is designed to supply power demand of pump stations. the aim of this design is minimization of net present cost of the hybrid system. optimization problem is subject to reliable supply of the demand. the system is investigated in the north west of iran (meshkinshahr) and the local data is applied. about 12 pump stations are found ...
background: the aims of this study were to examine the prevalence of trichomoniasis among women aged 18 to 48 yr in ardabil, northwestern iran and the relationship between demographic factors and the risk of infection. methods: vaginal discharge samples of 914 women aged 18 to 48 yr, referred to gynecology clinic of sabalan hospital of ardabil, iran in 2014, were collected and trichomonas vagin...
