Seeds of Haloxylon (H. pericae, H. aphyllum, and H. ammmodendron) were collected from Sabzevar and Gonabad regions. The seeds were kept in the refrigerator for isolation of the fungi after determining the germination rate and moisture content. The recommended methods by International Seed Testing Association (I.S.T.A.) for isolation of seedborne fungi were followed throughout this study. The fu...
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...
سیاه تاغ (haloxylon aphyllum) یکی از مهمترین گونه های موجود در مناطق خشک است که کاربرد گسترده ای در تثبیت شن و بیابان زدایی دارد. با وجود مقاومت بالای این گیاه در برابر تنش های محیطی ازجمله خشکی، احتمال وجود مقاومت بیشتر در جمعیت های مختلف آن وجود دارد. بر این اساس برای ارزیابی میزان تحمل جمعیت های مختلف به تنش خشکی، آزمایشی با استفاده از شش جمعیت غالب شامل جمعیت های برگرفته از استان های یزد (د...

Abstract 34 types of pests were found on haloxylon and other sand-retaining plants planted in the dry area Aral Sea. The main dominant species these are large small humpback grasshoppers. When insecticide Imitrin 20% sus.K. was tested grasshoppers at 0.05 L/ha distribution patter measurement against 2-3-year-old nymphs 0.1 4-5-year-old nymphs: after 3 hours - 89.2-87.4%, 24- 95.1-94.0% 72 96.3-...
رویش گونههای گیاهی در یک منطقه تحتتأثیر فاکتورهای محیطی و زیستی آن منطقه میباشد. بهطوریکه برای تعیین رویشگاه بالقوه گونههای گیاهی انجام مطالعاتی در زمینه نیازهای اکولوژیکی گونهها و خصوصیات محیطی منطقه مورد مطالعه ضروریست. در این تحقیق رویشگاه بالقوه دو گونه زرد تاغ (Haloxylon pesicum) و سیاه تاغ (Haloxylon aphyllum) در منطقه سیستان با استفاده از تکنیک سامانه اطلاعات جغرافیایی(GIS) تعیین ...
Anti-aging activities of extracts from Tunisian medicinal halophytes and their aromatic constituents
Six medicinal halophytes widely represented in North Africa and commonly used in traditional medicine were screened for pharmacological properties to set out new promising sources of natural ingredients for cosmetic or nutraceutical applications. Thus, Citrullus colocynthis, Cleome arabica, Daemia cordata, Haloxylon articulatum, Pituranthos scoparius and Scorzonera undulata were examined for th...
