25. Conservation system improves soil microbial quality and increases soybean yield in the Northeastern Cerrado
ABSTRACT The conservation tillage systems is based on the surface protection by crop residue and reduced soil disturbance. These two principles can favor the soil quality and promote sustainable agricultural systems. The study was developed with the objective of measure soil microbial biomass, soil basal respiration, enzymatic activity and soybean yield in c

26. FLORISTIC COMPOSITION AND DIVERSITY IN TERRA FIRME FOREST UNDER WATER STRESS IN THE AMAZON
ABSTRACT The studies on floristic composition are an aid in the understanding of the structure and dynamics of the plant communities, fundamental parameters for its management and conservation. Thus, the objective of this work was to evaluate the floristic composition, species richness, Shannon’s diversity and models of species abundance over a 10-year per

28. Nutritional, physicochemical and anatomical evaluation of creole corn varieties from the region of the Costa Chica of Guerrero
Abstract Corn (Zea mays) is the most consumed cereal in México, so it is necessary to know the nutritional and anatomical quality of the grains, which have been the main conservation and consumption criteria of the prehispanic peoples. This practice has allowed to preserve varieties of Creole corn, however, due to the lack of knowledge of these characterist

29. EVALUATION OF DIVERSITY AND GENETIC STRUCTURE AS STRATEGIES FOR CONSERVATION OF NATURAL POPULATIONS OF Dalbergia nigra (Vell.) Allemão ex Benth.
ABSTRACT: The evaluation of diversity and genetic structure allows us to verify with precision the effect of evolutionary and anthropic processes on species. The objective of this research was to evaluate the divergence and the genetic structure of two natural populations of Dalbergia nigra, using molecular markers Inter Simple Sequence Repeats (ISSR). Leaf

30. Tillage systems and cover plants change organic fractions of phosphorus in oxisol of eastern Amazonia
ABSTRACT Due to the large extent of degraded areas in the Amazon, the use of conservation systems is very important to contain the advance of the agricultural frontier, and may favor the availability of nutrients such as phosphorus (P). This study evaluated effect of tillage systems on and cover plants distribution of organic P fractions (Po) in oxisol under

31. Bromatological aspects of Lentinus crinitus mushroom (Basidiomycota: Polyporaceae) in agroforestry in the Cerrado
Abstract Much of the diversity of mushrooms is still unknown to science. In the search for new edible mushrooms, we began to look at the traditions of Amazonian forest peoples in order to learn about the potential for edible mushrooms among other species. In particular, the Yanomami people launched the encyclopedia of food (Sanoma) in 2016 to preserve their

32. SHADING AS A DETERMINANT FACTOR FOR THE SURVIVAL AND GROWTH OF Cabralea canjerana IN SOUTHERN BRAZIL
ABSTRACT Plantations with native tree species, which emphasize biodiversity conservation, may not succeed because of a lack of forestry knowledge about the native species. Cabralea canjerana is an important tree species, which is rarely present in area restoration programs because of the difficulty in establishing it in plantations. Despite this, the species

33. Conservation of crisp lettuce in different post-harvest storage conditions
ABSTRACT The objective of this work was to evaluate the post-harvest quality and the final storage time of the hydroponic crisp lettuce ‘Brida’, conditioned in different types of plastic packaging and environments. The statistical design was a completely randomized 3x2 factorial design, with 3 types of packages (control (without plastic packaging), perf

34. Conservation of species-rich subtropical grasslands: traditional management vs. legal conservation requirements in primary and secondary grasslands
ABSTRACT Land-use change is the main cause of biodiversity losses, and for grasslands includes changes in management. The last 10 years has seen afforestation of traditionally grazed grasslands increase considerably in the understudied Serra do Sudeste region of the Brazilian Pampa, turning the region into a mosaic of tree plantations, natural ecosystems (pa

35. Taxonomic study of Marsypianthes Mart. ex Benth. (Hyptidinae, Lamiaceae) in Brazil
ABSTRACT Marsypianthes is a Neotropical plant genus distributed from southern Mexico to northeastern Argentina. It is composed of six species - M. arenosa, M. burchellii, M. chamaedrys, M. foliolosa, M. hassleri, M. montana - with all occurring in Brazil except for M. arenosa, which occurs in Mexico. Marsypianthes burchellii, M. foliolosa and M. montana are

36. Evaluation of quality parameters and chromatographic, spectroscopic, and thermogravimetric profile of Patauá oil (Oenocarpus bataua)
Abstract The objective of this research was to evaluate the quality parameters and the chromatographic, thermogravimetric, and spectroscopic profile of Patauá oil (Oenocarpus bataua). All analyses were performed according to the Recommended Practices of the American Oil Chemists’ Society (AOCS). The parameters obtained indicate conservation quality standa
