No presente estudo, verificou-se a interferencia da macrofauna edafica sobre os atributos fisicos e quimicos e sua relacao com a reflectancia espectral de um Latossolo Vermelho-Amarelo (LV), Terra Roxa Estruturada latossolica (TR) e Vertissolo (V). Esses solos localizam-se em tres pontos ao longo de uma topossequencia da regiao de Piracicaba (SP). As amostras direcionadas para os agregados formados pelas formigas cortadeiras (Atta sp.), cupins (Cornitermes cumulans) e minhocas (Pontoscolex corethrurus), os quais foram comparados com o solo-controle sem atividade visivel e recente dos animais (testemunha). Foram avaliadas a granulometria e a composicao quimica das amostras de solo. O comportamento espectral do solo foi obtido em laboratorio, utilizando espectroradiometro entre 400 e 2.500 nm. Os coprolitos de minhoca apresentaram 2 a 3 vezes mais fosforo e um incremento de 30 a 50% na materia organica em relacao ap horizonte superficial do solo. Os agregados de cupins e formigas apresentaram composicao quimica semelhante a dos horizontes subperficiais dos solos. O comportamento espectral dos agragados biologicos variou conforme sua composicao quimica e profundidade de acaodos animais. No caso da minhoca, as curvas de reflectancia foram semelhantea as do horizonte superficial para os tres solos. Para as caracteristicas de cupim e formiga, tanto a composicao quimica como o comportamento espectral corresponderam ao horizonte subperficial no LV e TR. |

Pinus taeda (loblolly pine) is a widely-cultivated conifer that is particularly prevalent in the southeast United States and Southern Brazil. Some companies in Brazil are working with the third generation of improvement and other clonal tests of this species. The present study analyzed the interaction of genotype ×environment (G ×E) in clonal tests of loblolly pine planted in the South and Southeast regions of Brazil. For this, 75 clones and three commercial controls were tested using a randomized block design, with eight replications, and one plant per plot repeated across four sites. Measurements were performed at 11 years of age for diameter at breast height (dbh), total height, and volume. The GGE biplot and the Harmonic Mean of the Relative Performance of Genotypic Values (MHPRVG) methods were used to study the effects of G×E on dbh. The dbh was chosen because it is less subject to measurement errors and highly correlated with volume. The mean of heritability in the broad-sense among sites for dbh was high (0.89), as was the genotypic correlation between sites (0.78). Among the four tested environments, two sites can be considered as one mega-environment. Through the analysis, it was possible to verify the low magnitude of the effects of G × E on the tested clones. The best performing clones among all tests can be selected to produce commercial stands in areas with similar environmental characteristics to the sites tested herein. Thus, the composition of two breeding zones is recommended considering the tested clones.
