Orientador: Ananda Virginia de Aguiar / Resumo: The aim is to propose a management plan for progeny and provenance tests of Astronium fraxinifolium Schott and Jacaranda cuspidifolia Mart. It will be based on knowledge of genetic variability in an effort to promote the conservation of their genetic potential for commercial and environmental purposes. The test was originally installed in 1996 in Selvíria, Mato Grossa do Sul (MS) using an experimental design of randomized complete block design. We applied a total of 30 treatments (progenies) of provenance in Ilha Solteira, São Paulo (SP) and 30 treatments of provenance in Selvíria, MS with five repetitions for A. fraxinifolium and 30 treatments and 10 repetitions for J. cuspidifolia. The experimental plots were installed in a linear array, with 10 plants per plot, spaced 3 × 1.5m in alternate plantings. The silvicultural traits of both species were measured from 18 years after planting and sex determination of A. fraxinifolium individuals. The estimates of variance components and genetic parameters were obtained by employing the genetic statistical software SELEGEN-REML / BLUP. To investigate the genetic diversity the Mahalanobis distances and grouping of Tocher optimization model was used. It detected significant differences among provenances for DAP and ALT, between and within progenies for all growth traits, except FOR within progenies in A. fraxinifolium. The heritability coefficient average level progenies ranged from 0.59 to 0.89 and individual heritability from 0.14 to... (Resumo completo, clicar acesso eletrônico abaixo) / Mestre
