Baseline data represent one of the important stages of Environmental Impact Assessment (EIA) procedure that describes the existing environment of the study area and surrounding areas in enough detail to allow the environmental impacts of the proposed area to be accurately and adequately assessed, and future changes and effects can be measured. Baseline data may be inaccurate, difficult to obtai...
iran is widely drought prone, considering its semi-arid climate. eleven wheat cultivars differing in yield potential and drought resistance were employed to determine the possible relationship among grain filling rate and duration, stem reserves remobilization and grain yield under either irrigated (ir) or non-irrigated (nir) conditions at gerizeh research station in sanandaj for a duration of ...
دو گونه جدید از جنس گون برای ایران و جهان شرح داده شده و تصاویر آنها ارائه می گردد و چک لیستی از گون های ارتفاعات کوه بزقوش ارائه می گردد که قریب 75 گونه گون براساس فلورا ایرانیکا شناسایی و ارائه می گردد. گونه های جدید عبارتند از Astragalus Sect. (Incani) turkaman-chaiensis و Astragalus Sect. (Malacothrix) bozghoushensis صفات تاکزومیک گونه های مذکور ارائه شده و با نزدیک ترین گونه ها مقایسه می شود.
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...
