Evaluation of Biological Nitrification Inhibition (BNI) Capacity in a Biparental Mapping Population of Brachiaria humidicola
Soil nitrogen (N) loss due to rapid nitrification (oxidation of ammonium to nitrate) is a serious problem with economic and environmental implications. As a result, a large proportion of N fertilisers applied to crops are lost to the environment via nitrate leaching and nitrous oxide emissions. The tropical pasture grass Brachiaria humidicola (Bh) exudes organic molecules from roots that inhibi...
متن کاملWaterlogging-induced changes in root architecture of germplasm accessions of the tropical forage grass Brachiaria humidicola
Waterlogging is one of the major factors limiting the productivity of pastures in the humid tropics. Brachiaria humidicola is a forage grass commonly used in zones prone to temporary waterlogging. Brachiaria humidicola accessions adapt to waterlogging by increasing aerenchyma in nodal roots above constitutive levels to improve oxygenation of root tissues. In some accessions, waterlogging reduce...
متن کاملEvidence for biological nitrification inhibition in Brachiaria pastures.
Nitrification, a key process in the global nitrogen cycle that generates nitrate through microbial activity, may enhance losses of fertilizer nitrogen by leaching and denitrification. Certain plants can suppress soil-nitrification by releasing inhibitors from roots, a phenomenon termed biological nitrification inhibition (BNI). Here, we report the discovery of an effective nitrification inhibit...
متن کاملCyathostomin larvae: presence on Brachiaria humidicola grass during the rainy and dry seasons of Brazil.
The presence of cyathostomin larvae is directly associated to climatic conditions of each region. This study aimed to evaluate the ecology of infective larvae on Brachiaria humidicola during the dry and rainy seasons from October 2007 to September 2008 in a tropical region, Rio de Janeiro state, southeastern Brazil. Stools were collected from the rectum of horses naturally infected with cyathos...

ممانعت از نیتریفیکاسیون در اکوسیستم‌های طبیعی چندین دهه است که مطرح می‌باشد. این اثرات ممانعت کنندگی یک ویژگی ژنوتیپ‌های وحشی می‌باشد تا ارقام تجاری. بسیاری از گیاهان مخصوصاً گراس‌ها نشان داده شده اند که دارای این خاصیت ممانعت از نیتریفیکاسیون هستند و اخیراً برخی ژنوتیپ‌های Brachiaria مخصوصاً humidicola Brachiaria توجه زیادی را به سبب نقش آن‌ها در کاهش میزان نیتریفیکاسیون در خاک از طریق ترشحات ریش...
