Rhizosphere effect and salinity competing to shape microbial communities in Phragmites australis (Cav.) Trin. ex-Steud.
Rhizobacterial communities associated with Phragmites australis (Cav.) Trin. ex Steud. in a hypersaline pond close to Wuliangsuhai Lake (Inner Mongolia - China) were investigated and compared with the microbial communities in bulk sediments of the same pond. Microbiological analyses have been done by automated ribosomal intergenic spacer analysis (ARISA) and partial 16S rRNA gene 454 pyrosequen...
متن کاملphotosynthetic responses in reed (phragmites australis (cav.) trin. ex steud.) seedlings induced by different salinity-alkalinity and nitrogen levels
many phragmites-dominated wetlands have been markedly salinized and alkalinized in the songnen plain, northeastern china. agricultural wastewater with high nitrogen content has been discharged into these alkalinized-salinized wetlands. to understand the effect of salinity-alkalinity on reed (phragmites australis) seedlings at various nitrogen levels, we examined photosynthesis rate, chlorophyll...
متن کاملتأثیر اختلاط نانورس و خاکستر ساقه نی (Phragmites australis (Cav.) Trin. ex Steud) در تثبیت بستر خاکی ریزدانه راههای جنگلی
امروزه استفاده تلفیقی از تثبیتکننده های زیستی خاک مانند انواع خاکسترها و نانوذرات برای تسریع و تقویت فرآیند تثبیت بستر خاکی تورم‌پذیر راهها بیش از پیش مورد توجه قرار گرفته است. خاک رس تورم‌پذیر مورد استفاده در این پژوهش از مسیر عبور جاده‌های پیشنهادی سری دو طرح جنگلداری دکتر بهرام‌نیا واقع در استان گلستان تهیه شد. برای آمادهسازی تیمارهای تثبیت خاک، ابتدا درصدهای وزنی اختلاط 0/5 نانور...
متن کاملInteraction of cadmium with glutathione and photosynthesis in developing leaves and chloroplasts of Phragmites australis (Cav.) Trin. ex Steudel.
We investigated how the presence of cadmium (Cd) at the emergence of Phragmites australis Trin. (Cav.) ex Steudel plants from rhizomes interacted with leaf and chloroplast physiological and biochemical processes. About 8.5 nmol Cd mg-1 chlorophyll was found in leaves, and 0.83 nmol Cd mg-1 chlorophyll was found in chloroplasts of plants treated with 50 microm Cd. As a result, a 30% loss of chlo...
متن کاملEffect of EDTA treatment method on leaching of Pb and Cr by Phragmites australis (Cav.) Trin. Ex Steudel (common reed)
One of the major problems about the chelant-enhanced phytoextraction is the potential metal leaching associated with chelant application. A glasshouse pot experiment was conducted to investigate phytoextraction efficiency of common reed (Phragmites australis (Cav.) Trin. ex Steudel) for Lead and Chromium and to determine EDTA (ethylenediaminetetraacetic acid) enhancement of the mobility and phy...
