تاثیر بازدارندگی ترشحات رشد brachiaria humidicola نیتریفیکاسیون
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...
متن کاملSalt stress response and proline accumulation in Brachiaria humidicola plants with and without mycorrhizal inoculation.
The work was carried out to investigate the effects of different concentrations of NaCl on Brachiaria humidicola Rendle in the presence and absence of Glomus etunicatum Becker and Gerdemann, as well as to evaluate some growth parameters and the accumulation of free proline in the plant leaves. The soil used was a Neosoil Fluvic Eutrophic with pH of 6.5, organic matter, 12.8 g kg-1 and soil text...
متن کاملPreference for C4 shade grasses increases hatchling performance in the butterfly, Bicyclus safitza
The Miocene radiation of C4 grasses under high-temperature and low ambient CO 2 levels occurred alongside the transformation of a largely forested landscape into savanna. This inevitably changed the host plant regime of herbivores, and the simultaneous diversification of many consumer lineages, including Bicyclus butterflies in Africa, suggests that the radiations of grasses and grazers may be ...

Mitotic behavior in root tips of Brachiaria genotypes with meiotic chromosome elimination during microsporogenesis.
Three accessions of Brachiaria brizantha, three of B. humidicola, and two interspecific hybrids between B. ruziziensis and B. brizantha were analyzed with regard to their mitotic behavior in root tips. All these genotypes revealed chromosome elimination or lack of chromosome affinity in previous analyses of microsporogenesis. Analyses of root tips showed a normal mitotic division in all accessi...
