climate changes and global warming are considered as very important challenges of sustainable development. carbon sequestration is the easiest and cheapest way to reduce the greenhouse gases, especially carbon which constitutes the largest portion of them. in the present study, the potential of carbon sequestration in four plant species of atriplex canescens, haloxylon persicum, artemisia siebe...
today, environmental crisis and loss of natural resources are the principle causes of the creation of environmental management systems. the optimal management of natural resources requires the assessment and classification of ecological and environmental potentials. using this method, the abilities and restrictions of resources can be recognized, and their future trends can be predicted. nebka ...
. زنجرکهای جمعآوری شده در الکل 75 درصد نگهداری و اطلاعات محل و میزبان آنها ثبت و برای شناسایی به متخصصان مربوطه ارسال شدند. در مجموع 24 نمونه زنجرک از روی 14 میزبان در عرصههای طبیعی استان جمعآوری گردید که تاکنون 10 گونه از روی 6 گیاه توسط محمد تقیزاده و مرحوم میرزایانس شناسایی شده است. از این تعداد 4 گونه از روی بنه (Pistacia atlantica)، 3 گونه از روی رمس (Hammada salicornica) و از روی هر ...
Climate change is one of the most important challenges in sustainable development that has negative effects on the ecosystems, land and water. The main cause of this phenomenon, increasing the concentration of CO2 in the atmosphere. The main method for reducing at CO2 atmosphere is increasing global carbon storage in soils, in other hand 75% total carbon stock on land has stored in soils. The s...
The aim of the present study was to evaluate the spatial and temporal changes of NPP in different biomes of Isfahan province from 2000 to 2014 and their response to climatic factors. For this purpose, the NPP data of the MODIS satellite were collected and the map of climatic variables was produced using various interpolation methods. The investigation of the spatial and temporal variations of N...
شوری یکی از مشکلات در حال افزایش جهان است که سطح وسیعی از اراضی کشور ما را نیز دربرمیگیرد. با توجه به افزایش سطح اراضی شور و کمبود اراضی مطلوب در کشور، شناسایی گیاهان مرتعی مقاوم به شوری اهمیت زیادی دارد. به منظور تعیین اثر سطوح مختلف شوری بر جوانهزنی گونههای اشنان (Seidlitzia rosmarinus)، سیاهتاغ (Haloxylon aphyllum)، سفیدتاغ (Haloxylon persicum)، پرند (Pteropyrum aucheri)، سیاهشور (Sue...
BACKGROUND The central function of chloroplasts is to carry out photosynthesis, and its gene content and structure are highly conserved across land plants. Parasitic plants, which have reduced photosynthetic ability, suffer gene losses from the chloroplast (cp) genome accompanied by the relaxation of selective constraints. Compared with the rapid rise in the number of cp genome sequences of pho...
Haloxylon salicornicum (H. salicornicum) is a plant that is frequently taken as a tea by Bedouin women in Egypt who are experiencing difficulties during pregnancy, as well as to provide relief from dysmenorrhoea. Despite its medical use, there has been no detailed evaluation of the effect of this plant on uterine tissue. Therefore, the initial aim of this study was to determine whether H. salic...
Haloxylon ammodendron, a perennial xero-halophyte, is an essential species for investigating the effects of drought on desert tree. To gain a comprehensive knowledge on the responses of H. ammodendron to drought stress, we specially performed the molecular and physiological analysis of H. ammodendron in response to -0.75 MPa osmotic stress for six and 24 h in lab condition via RNA-seq and digit...
Desert plants are exposed to a combination of environmental stress conditions, including water deficit, high temperature and high irradiance. We focused on antioxidative protection systems of C4 desert plant Haloxylon ammodendron and C3 desert plant Hedysarum scoparium within arid dune ecosystem with artificial controlling water availability. The activities of antioxidative enzymes (SOD, POD an...
