بهمنظور بررسی توان گیاه آتریپلکس برای ترسیب کربن، از گونه آتریپلکس کانیسنس (Atriplex canescens) در ایستگاه مرتع نودهک در استان قزوین استفاده شد. این گونه گیاهی در طرح آماری کرت خرد شده در قالب بلوکهای کاملاً تصادفی کاشته شد. تیمارهای اصلی فاصله کاشت بوته (تراکم) در دو سطح 2×2 متر و 4×4 متر و هر تیمار اصلی شامل تیمارهای فرعی بلندی (ارتفاع) هرس در چهار سطح (تیمار بدون هرس یا شاهد، هرس ...
to find the effect of atriplex canescens on soil chemical properties, two adjacent areas, each with and area of 1 ha, were selected in hossein abad hapeshloo shahryar. in one area it was planted atriplex canescens in 2003 while the later one without atriplex canescens was considered as control area. to sample soil, random- systematic method was used along 3 transects with a length of 100 m. in ...
it has often been stated or implied that grazing is an important factor in the land degradation process, a suggestion supported by various research projects, and this study investigated the effect of livestock grazing on stem height, crowncover, production, basal diameter, stem biomass, litter, leaf-stem index (leaf to stem weight) , root diameter and weight and seed production per individual o...
Microbial diversity associated with micropropagated Atriplex species was assessed using microscopy, isolate culturing, and sequencing. Light, electron, and confocal microscopy revealed microbial cells in aseptically regenerated leaves and roots. Clone libraries and tag-encoded FLX amplicon pyrosequencing (TEFAP) analysis amplified sequences from callus homologous to diverse fungal and bacterial...
One of the methods of biological sand dune stabilization and reclamation of desert, Planting resistant species in areas of bare and covered with dry conditions. One of the plants used for the purpose of is Atriplex canescens . Considering that the successful establishment of plants in arid regions is a prerequisite for the success of the restoration area and since the medium first is where the ...

حدود 15 درصد از اراضی کشور ایران تحت تأثیر شوری قرار دارند. گونه های جنس آتریپلکس جهت کشت در این گونه اراضی از جایگاه ویژه ای بر خوردارند. این تحقیق طی سالهای 1373 تا پایان 1383 به منظور بررسی تاثیر فاصله کاشت و زمان و ارتفاع هرس بر عملکرد علوفه atriplex canescens در ایستگاه تحقیقات مرتع نودهک استان قزوین در یک طرح آماری کرت های دوبار خردشده در قالب بلوک های کامل تصادفی با سه تکرار به اجرا در...
some of arid regions problems of iran are saline and sodic soils. in improvement and reclamation of iranian arid rangelands, some foreign species of atriplex had been imported and adapted for many years ago. the most adapted species was atriplex canescens. at the present research, some environmental factors, vegetative characteristics (na, ca, mg and k), soil properties (moisture, ec, ph, solut...
