The tropical peatlands of southern Brazil are essential for the maintenance ofthe Atlantic Rain Forest, one of the 25 hotspots of biodiversity in the world.Although diazotrophic micro-organisms are essential for the maintenance ofthis nitrogen limited ecosystem, so far studies have focused only on micro-organisms involved in the carbon cycle. In this work, peat samples werecollected from three tropical peatland regions during dry and rainy seasonsand their chemical and microbial characteristics were evaluated. Our resultsshowed that the structure of the diazotrophic communities in the Braziliantropical peatlands differs in the evaluated seasons. The abundance of the genusBradyrhizobiumshowed to be affected by rainfall and peat pH. Despite theshifts of the nitrogen-fixing population in the tropical peatland caused byseasonality it showed to be constantly dominated bya-Proteobacteria followedbyCyanobacteria. In addition, more than 50% ofnifHgene sequences have notbeen classified, indicating the necessity for more studies in tropical peatland,since the reduction of N supply in the peatlands stimulates the recalcitrantorganic matter decomposition performed by peatland micro-organisms,influencing the C stock.
This manuscript reports the first ecological study of tropical peat-lands diazotrophic communities from the Brazilian Atlantic Rain Forest, one of the world?s largestbiodiversity hotspots. Based on culturing and culture-independent approaches, our results showed alter-ations in the structure of the diazotrophic communities in different seasons. The genusBradyrhizobiumabundance was affected by rainfall and peat pH. In addition, the great number of unclassifiednitrogen-fixing bacteria indicated the need for additional studies to guide future mitigation actions,since the reduction of N supply in the peatlands stimulates the recalcitrant organic matter decomposi-tion performed by peatland micro-organisms, influencing the C stock.

Abstract: The production of passion fruit in Mato Grosso is low in comparison with that of other Brazilian states and is insufficient to supply local demand. A key factor contributing to this poor performance is the use of mixed varieties that are susceptible to diseases such as Fusarium wilt. In this regard, cultivation of grafted plants would be advantageous in establishing healthy, homogenous and productive orchards. The aim of this study was to compare fruit production of non-grafted plants of the commercial cultivar Passiflora edulis BRS Gigante Amarelo grown under the climatic and soil conditions of Terra Nova do Norte, Mato Grosso, with the scion grafted onto rootstocks of native species/hybrids known to be resistant to Fusarium spp. Performances were determined by evaluating the number of fruits per plant, fruit production, average fruit mass and productivity. The rootstocks employed were P. edulis BRS Gigante Amarelo, P. nitida, P. alata, P. alata x P. maliformis, P. edulis BRS Gigante Amarelo x [(P. quadrifaria x P. setacea) F1 x P. incarnata], P. setacea x (P. speciosa x P. coccinea), and P. katsshbachu x (P. vitifolia x P. setacea). The best performances, with values in the ranges 183.6-232.8 fruits plant1, 33.5-39.2 kg plant-1, 165.8-190.9 g fruit-1 and 37-43 t ha-1, were observed with non-grafted plants and with the scion grafted onto the first four mentioned rootstocks. The other scion/hybrid rootstock combinations presented significantly lower values and their performances were considered moderate to poor. The results reported herein will contribute to the improvement of passion fruit orchards in Mato Grosso.
