در این پژوهش تأثیر تنش قلیائیت بر ویژگیهای فیزیولوژیک گیاه قرهداغ در سال 1391 تحت شرایط گلخانه ای در دانشگاه کاشان مورد بررسی قرار گرفت. در این مطالعه اثر تیمارهای مختلف اسیدیته (ph) آب آبیاری در دامنه قلیایی بر فراهمی عناصر غذایی و قندهای محلول در گیاه قرهداغ، در قالب یک طرح کاملاً تصادفی مورد بررسی قرار گرفت. طرح مذکور حاوی 5 تیمار (هر تیمار شامل 4 تکرار) شامل شاهد و چهار سطح تنش: سطح اول ش...
کشور ایران دارای اقلیم گرم و خشک بوده و میزان بارندگی سالیانه آن250میلی‌متر است. بنابراین در کشور ایران با بارشی کم و توزیع نامناسب آن، استفاده موثر از فن‌آوری نوین برای بالابردن کارایی مصرف در منابع محدود آبی امری حیاتی است. یکی از این راهکارها برای حفظ و ذخیره رطوبت، استفاده از مواد فراجاذب خاک است. در این تحقیق تاثیر ماده معدنی زئولیت در سه سطح(0،10، 15درصد وزنی) و سوپرجاذب جیوهوموس درچهار س...
Water crisis is an important issue in arid and semi-arid regions like Iran. Due to drought events, the situation has become more acute in recent years. Therefore, where good quality water is not available, the use of unconventional water has increased considerably. One of these resources is municipal wastewater that can also provide some of the nutrients needed for plant nutrition. Therefore, i...
BACKGROUND In this report, the isorhamnetin 3-o-robinobioside and its original extract, the ethyl acetate extract, from Nitraria retusa leaves, were evaluated for their ability to induce antioxidant and antigenotoxic effects in human chronic myelogenous leukemia cell line. METHODS Nitraria retusa products properties were carried out by firstly evaluating their effects against lipid peroxidati...
BACKGROUND Here, phytochemical profile of Nitraria retusa (N. Retusa) leaf extracts was identified and their ability to induce apoptosis and inhibiting growth of melanoma cells and enhancing melanogenesis of B16F10 melanoma was evaluated. METHODS The Apoptosis was evidenced by investigating DNA fragmentation, and Acridine orange/ethidium bromide staining. Amounts of melanin and tyrosinase wer...
Nitraria schoberi (Ghar-e-Daghin in Persian) from Zygophyllaceae (Nitrariaceae) family is considered as a wonderful exquisite plant in terms of its economical, medicinal, animal feed, significant values and also its unique characteristics of being tolerant to the soil salinity, drought and erosion. On the other hand, this plant is challenging with severe problems such as seed dormancy, plant gr...
geostatistical approaches have great importance because they include spatial correlation of geographic data. present study evaluated the efficiency of geostatistical techniques and demonstrated their capabilities in studying the soil variables(soil texture (sand percent), ec and so4-2) in the important plant community of nitraria schoberi in meighan desert, arak. a regular grid on the map compr...
abstract this study aimed to investigate the effects of urban wastewater on some soil physical and chemical properties in segzi, east isfahan. six sites were selected considering the planted species (haloxylon persicum and nitraria schoberi) and irrigation types (control or no irrigation, water logged and furrow irrigation methods). the 4 to 12 replications were chosen in each site depending on...
the effects of saline groundwater on soil properties and yield of three range plants in saline soils
the use of saline groundwater resources, in addition to save fresh water, could be used in production of forage in saline soils. in order to do it, the area in northern ardakan, yazd province with saline ground water (ec= 11.25ds/m, sar= 16.7) and saline and alkaline soil (ec=27.3ds/m, esp= 30.2%) was selected for planting of atriplelentiformis, seidlitzia rosemarinus, and nitraria schoberi. th...
