Este trabalho reveste-se de grande importância no que tange ao levantamento de recursos naturais nessa Fazenda Experimental, com informações sobre caracterização, classificação taxonômica e mapeamento dos solos, em escala de detalhe. Os resultados deste trabalho apresentam potencialidade para dar suporte às pesquisas agronômicas aplicadas não apenas na propriedade analisada, mas igualmente em áreas com condições edafoclimáticas semelhantes, no contexto das ações de transferência de tecnologias desenvolvidas pela Embrapa Amazônia Oriental. |

Photochemical responses are directly dependent on the level of incident solar radiation during the initial establishment of forest species. The aim of the current study was to evaluate chlorophyll a fluorescence in 2-year-old Bertholletia excelsa seedlings from July to October 2017. Samples were acclimated on polyolefin screens under different quantitative (35%, 50%, 65% and 80%) and qualitative (thermo-reflective, red, blue and green screens, at 50% solar radiation attenuation) shading levels and under full sun at the 77th, 105th, 122nd and 150th days after acclimation - DAA - (73 days) in Sinop County - MT. Estimates of effective quantum yield (ΦPSII) and electron transport rate (ETR) were performed in the OS5p Fluorometer (150 μmol m-2 s-1 PAR). The experimental design was completely randomized in factorial arrangements (5 x 4) and (6 x 4) (shading levels x time), with three repetitions (seedling). Data were subjected to analysis of variance, at 5% and 10% significance levels. There was significant interaction between shading and time; the maximum ETR (38.26 μmol m-2 s-1) and ΦPSII (0.77) points were estimated at the 116th DAA, at 77% and 76% shading levels, respectively. Red and green screens increased fluorescence parameters throughout the growth period. Seedlings showed low ability to differentiate changes in the quality of the intercepted light, however, those acclimated under full sun were less efficient to photochemically dissipate light energy. We conclude that intermediate shading levels (50% and 65%) increase the efficiency of Brazil nut tree seedlings in converting solar energy into chemical energy.
