| The objective of this study was to generate information relative to the allele distribution and dynamics within and among populations of Araucaria angustifolia, a naturally-occurring conifer in the south of Brazil, being known popularly as "pinheiro-do-Paraná", "araucaria" or pine tree. In order to elucidate the levels and the distribution of the genetic variability, the population's genetic structure and the genetic distance among natural populations of this species with different levels of disturbance in different geographical areas were studied in detail. For this, samples of leaf tissue were collected from 328 adult individuals in nine natural populations in Santa Catarina State. To analyze the samples, the allozyme technique was applied in starch gel... |

| The pineapple guava (Acca sellowiana), known in portuguese as the goiabeira-serrana or "Feijoa", is a native fruit tree from southern Brazil and northern Uruguay that has commercial potential due to the quality and unique flavor of its fruits. Knowledge of genetic variability is an important tool in various steps of a breeding program, which can be facilitated by the use of molecular markers. The conservation of repeated sequences among related species permits the transferability of microsatellite markers from Eucalyptus spp. to A. sellowiana for testing. We used primers developed for Eucalyptus to characterize A. sellowiana accessions. Out of 404 primers tested, 180 amplified visible products and 38 were polymorphic. A total of 48 alleles were detected... |

| A goiabeira-serrana (Acca sellowiana Berg.) é uma mirtácea nativa do planalto meridional brasileiro, com dispersão secundária no Uruguai, e produz um fruto de sabor único. Plantas de um pomar comercial composto por duas famílias de meios-irmãos (FMI1 e FMI2) foram avaliadas, com o objetivo principal de analisar a variabilidade fenotípica de várias características. As médias (± desvio-padrão) obtidas para as características avaliadas, no ano de 2000, foram: produtividade (29,2±35,0 e 55,1±53,4 frutos por planta); altura (2,2±0,7 m e 2,7±0,8 m); diâmetro de copa (1,9±0,7 m e 2,1±0,7 m); número de ramificações a 20 cm do solo (2,4±1,5 e 1,6±1,2) e distância entre o estigma e as anteras na flor (0,5±0,2 cm e 0,2±0,2 cm), para as plantas da FMI1 e da FMI2,... |
