Abstract: Pau de balsa is a forest species that is native to the Amazon and stands out for its rapid growth, being an option for a productive and profitable activity. The objective of this study was to select phenotypically superior pau de balsa trees and verify the dissimilarity between them and their respective origins in order to identify individuals for wood production. Three distinct populations trees in plantations of pau de balsa implanted in January 2011 in the municipality of Guarantã do Norte, Mato Grosso, Brazil, were evaluated as to their characteristics of commercial importance. Among the trees evaluated, highlight the genotype A09 as a candidate for the matrix in breeding programs of the species due to its superiority in the characteristics of diameter at breast height and total height. Genotypes A09 and IF03 are the most genetically distant and S02 and S09 the most similar. The principal component analysis explained 81.24% of all the variance of the characteristics analyzed in the first two variables. With the results obtained, it was possible to identify the superior characteristics of the Ecuadorian genotypes A01, A09 and A14; the first two present good characteristics for wood production, and the third presents the lowest basic density of wood. | Resumo: O pau de balsa é uma espécie florestal nativa da Amazônia, e destaca-se pelo rápido crescimento e, portanto, considerada como uma opção de atividade produtiva e rentável. Objetivou-se neste estudo selecionar árvores de pau de balsa superiores fenotipicamente e verificar a dissimilaridade entre elas e suas respectivas origens, afim de identificar indivíduos para a produção de madeira. Foram avaliadas as árvores de plantios de pau de balsa implantado em janeiro de 2011 no município de Guarantã do Norte, Mato Grosso, Brasil, em três populações distintas e avaliadas características de importância comercial. Entre as árvores avaliadas podemos destacar o genótipo A09 como um candidato à matriz em programas de melhoramento da espécie, devido à superioridade nas características de diâmetro à altura do peito e altura total. Os genótipos A09 e IF03 são os mais distantes geneticamente e S02 e S09 os mais similares. A análise de componentes principais explicou 81,24% de toda a variância das características analisadas logo nas duas primeiras variáveis. Com os resultados obtidos foi possível selecionar os genótipos equatorianos A01, A09 e A14, os dois primeiros por apresentar boas características para a produção de madeira, e o terceiro por apresentar a menor densidade básica da madeira.

Pedotransfer functions are methods proposed with the objective of obtaining indirect information, with greater speed and ease to estimate various soil attributes. Thus, the objective of this work was to generate and obtain pedotransfer functions (PTFs) to predict the moisture retained at specific potentials in a Planosol under integration crop-livestock-forest system in the Agreste of Paraíba, three years after implementing the system. The research was conducted in an area located at the Experimental Station of the Paraíba Company of Research, Rural Extension and Land Regularization - EMPAER, in the district of Alagoinha, PB. The experimental design utilized was that of randomized blocks with 5 integration systems and 4 repetitions. The treatments were structured as 1) Gliricídia + Brachiaria decumbens (GS+BD); 2) Mimosa caesalpiniaefolia+ Brachiaria decumbens (MC+BD); Tabebuia alba + Brachiaria decumbens (TA+BD); 4) Zea mays + Brachiaria decumbens (ZM+BD); 5) Brachiaria decumbens (BD). Soil samples with undisturbed structure were collected in three layers (0.00-0.10; 0.10-0.20 and 0.20-0.30 m). Soil water retention was determined in the following matrix potentials: Psi m = -33 e -1,500 kPa. According to the results, it was possible to observe an increase in the available water content in all treatments, as a function of depth, and the soil granulometry was shown to be related to the increase of clay particles in the subsurface. |
