Abstract The variability of metric traits has been studied in 20 Kazakhstan populations three Nitraria species ( N. schoberi L., sibirica Pall., and komarovii Iljin & Lava ex Bobrov). According to the results, differs from small leaves, fruits, seeds, as well structural features inflorescences flowers. is characterized by a greater number flowers per inflorescence (25–66 on average) than (1...

Abstract: The presence of rather complicated alkaloids in Nitraria species as racemates suggests a non-enzymic biosynthesis of the skeletons, which implies that these reactions should be reproducible in the lab. In the case of Nitramine and Nitraramine the total synthesis was approached starting from highly symmemc glutarimide derivatives. Insight in the biosynthesis of Nitraria alkaloids led t...

Desert vegetation plays significant roles in securing the ecological integrity of oasis ecosystems in western China. Timely monitoring of photosynthetic/non-photosynthetic desert vegetation cover is necessary to guide management practices on land desertification and research into the mechanisms driving vegetation recession. In this study, nonlinear spectral mixture effects for photosynthetic/no...

salinity is one of major stresses which can severely limit plant production, especially in the arid and semi-arid regions. the present study was carried out to evaluate the impact of salinity stress on some physio-biochemical parameters in nitre bush plants (nitraria schoberi). thus, an experiment was carried out under natural conditions and salinity stress was induced by a combination of diffe...

Improving water use efficiency and soil properties are two major factors for sustainable development in desert areas. Therefore, this research aims to study the effectiveness of a biological hydrogel, plant vegetation layer, sand and barley straw with rain harvesting techniques through micro-catchment operation on some soil properties including pH, Nitrogen, Electrical conductivity, Sodium Abso...

با هدف استفاده از فضای خالی بین Haloxylon ammodendron برای شناسایی و معرفی گونههای مناسب جهت کاشت همزمان باSeidlitzia Atriplex canescens، Salsola rigida از گونه های ،H. ammodendron بوتهای و تقویت اکوسیستم مناطق دارای پراکنشاستفاده شد. نحوه کاشت در قالب مدل آماری بلوکهای کامل تصادفی ، با 3 Anabasis setifera و Nitraria schoberi ،rosmarinusبلوک (تکرار) و هر بلوک با 6 تیمار در ایستگاه تحقیقات منابع...

امروزه پوشش گیاهی طبیعی در بسیاری از مناطق خشک بنا به علل مختلف، به‌شدت تخریب‌شده است؛ پدیده­ای که این مناطق را به‌سوی بیابانی­شدن سوق می­دهد. یکی از راهکارهای مدیریتی به­منظور جلوگیری از پیشروی بیابان، کشت انواع گیاهان سازگار (مانند درختچه قره­داغ)، از طریق جنگلکاری است و در این راستا کیفیت نهال­های مورد استفاده، نقش مهمی در رسیدن به این هدف دارند. از عوامل مؤثر بر کیفیت نهال­ها، می­توان به خص...
