The re-implantation and reproduction native plants project, which will run from June 2003 to May 2019, main part zones. most effective reducing aeolian mobile sediments were highlighted, along endangered plant species area, including Ly...
the aim of this research was to investigate the effect of index species, astragalusammodendron on the associated plants of agropyron tauri and bromus tomentellus fromdifferent aspects in shazand rangeland in southwest of markazi province. the effects ofspecies density and distribution pattern and then index species on the soil properties werestudied. based on the randomized – systematic method,...
A Gram-stain-negative, rod-shaped, motile bacterium, designated AER10T, was isolated from the roots of Ammodendron bifolium collected from Takeermohuer desert in Xinjiang Uygur Autonomous Region, northwestern China. Growth was found to occur from 10 to 45 °C, at pH 5.0-9.0, and could tolerate up to 10 % (w/v) NaCl. 16S rRNA gene sequence result indicated that the strain AER10T belongs to the ge...
During the study on the specimens of Astragalus sect. Ammodendron in the herbarium of Ferdowsi University of Mashhad (FUMH), based on the last and most recent sources, two new species, i.e. A. microfoliolatus sp. nova and A. rashed-mohasseli sp. nova were found and described. Morphological evidence confirmed that the belonging of these taxa to Astragalus sect. Ammodendron. The most important di...
این پژوهش به منظور بررسی اثر انواع مالچ بر حفظ رطوبت خاک نهالهای تاغ در استان سمنان در قالب طرح بلوک کامل تصادفی با 2 تیمار اصلی مالچ طبیعی و مصنوعی و دو تیمار فرعی پلاستیک سفید و سیاه و شن درشت و نرم هر یک با 3 تکرار در مناطق مختلف انجام شد. نهال های تاغی آماده به این منظور از گلدان جدا شده و به فاصله 3 متر از هم کاشته و انواع مالچ در حوزه تشتکها به ضخامت 5 سانتیمتر قرار گرفت. تیمار بدون ما...
تولید نهال گیاهان بومی و غیربومی در نهالستان یکی از مواد اولیه برای جنگلکاری در مناطق خشک بشمار میرود. یکی از عوامل مؤثر و تأثیرگذار بر روی تولید نهال در نهالستان تراکم بذر و عمق کاشت میباشد که در این ارتباط مطالعات وسیعی صورت گرفته است، بنابراین در این تحقیق سعی شده است تا تأثیر این دو عامل را بر فاکتورهای رویشی گونه زردتاغ بررسی نماییم. تاغکاریهای حسینآباد استان قم با مساحت 3180 هکتا...
due to the notable role of different land uses in carbon sequestration and emission, four treatments including rangeland as control, haloxylon plantation area, olea plantation (olive garden), and residential lands, were selected to study the effects of land use change on soil carbon sequestration and emissions in eivanakei rangelands, semnan province. carbon stocks in vegetation and soil of eac...
