Authors: L.D. Giustina, A.B. Baldoni, H. Tonini, V.C.R. Azevedo, L.G. Neves, F.D. Tardin, A.M. Sebbenn
Knowing the mating patterns is important to determine the number of trees necessary for seed collection for conservation ex situ, tree breeding and environmental reforestation purposes. We investigated B. excelsa individuals and fruits, to check mating system index variations in a population by using open-pollinated seeds whic.. Read More»

Minimum number of measurements for evaluating Bertholletia excelsa
Authors: A.B. Baldoni, H. Tonini, F.D. Tardin, S.C.C. Botelho and P.E. Teodoro
Repeatability studies on fruit species are of great importance to identify the minimum number of measurements necessary to accurately select superior genotypes. This study aimed to identify the most efficient method to estimate the repeatability coefficient (r) and predict the minimum number of measurements needed for a more a.. Read More»

Isolation and characterization of microsatellite markers for Bertholletia excelsa (Lecythidaceae) population genetic analysis
Authors: P.S. Sujii1, P.W. Inglis2, A.Y. Ciampi2, V.N. Solferini1 and V.C.R. Azevedo2
Seven polymorphic microsatellite markers were developed and validated for Bertholletia excelsa (Brazil nut tree) population genetic studies. This species is a widespread monotypic Amazonian tree with high non-timber economic value. Unfortunately, Brazil nut production is currently less than 25% of historical production levels, because of extensive defores.. Read More»
