The effect of palisade grass (Urochloa brizantha) was evaluated on the growth of five tree species from the Atlantic Forest biome in Seropédica, RJ, Brasil. This study consisted of five experiments in a completely randomized design. The effect of grass on the growth of Cedrela fissilis, Guazuma ulmifolia, Schinus terebinthifolius, Sapindus saponaria, and Hymenaea courbaril was tested in pots at each experiment. Height, collar diameter, and plant mortality were measured monthly. Shoot and root dry matter of tree species and grass were evaluated at 180 days. A strong interference of palisade grass was observed on the growth of the five studied species. The reduction of growth in height and collar diameter reached 32 and 29% in S. saponaria and 26 and 44% in G. ulmifolia, respectively. Grass interference was even higher on dry matter accumulation, promoting reductions in the shoot that ranged from 48% in H. courbaril to 90% in G. ulmifolia and S. terebinthifolius. Root dry matter of tree species was reduced between 28 and 84% in relation to the control without the presence of grass. The species C. fissilis had a mortality rate of 83% in coexistence with U. brizantha. The other species, except S. saponaria, presented mortality from 15 to 30% under competition. This study evidences the importance of controlling grasses in reforestation projects aiming higher gains in growth and survival of tree species |

The study of the microbiome related to fermentation in ruminants can help to optimize the conversion of animal protein. However, most species present in the rumen are unculturable , which makes the study of such microorganisms challenging. Advances in scientific knowledge, especially in the areas of molecular biology, biotechnology and bioinformatics, have paved the way to provide deeper genetic information on the rumen microbiome. Within this scenario, metagenomics and metatranscriptomics have been filling some gaps and deepening our knowledge about the microbiome. |
