Genetic diversity between and within populations of Handroanthus heptaphyllus (Vell.) Mattos using microsatellite markers

Abstract: ABSTRACT:Handroanthus heptaphyllus (Vell.) Mattos, popularly known as ipê-roxo, is a species of the family Bignoneaceae much appreciated for its beauty, excellent quality wood which is used for making medicinal products and also in reforestation programs of degraded areas, as well as landscaping and restoration. The aim of this study was to investigate the genetic diversity between and within populations of H. heptaphyllus using microsatellite markers. The 192 seedlings were produced from seeds collected on 30… Show more

“…Mattos (Bignoniaceae), synonym Tabebuia heptaphylla (Grose and Olmstead, 2007) also known as black lapacho is a heliophile meso hygrophytic species native to the tropical forests and riverine areas of Brazil and Argentina (Ramos et al, 2008;Olmstead et al, 2009;Mori et al, 2012). The characteristics of the wood, suitable for the manufacture of fine furniture, as well as the presence of certain secondary metabolites that impart insecticidal and medicinal properties, attracted the interest of companies for commercial exploitation of wild populations (Alonso, 2000;Martínez et al, 2012).…”

“…The characteristics of the wood, suitable for the manufacture of fine furniture, as well as the presence of certain secondary metabolites that impart insecticidal and medicinal properties, attracted the interest of companies for commercial exploitation of wild populations (Alonso, 2000;Martínez et al, 2012). Despite of the predatory exploration, use of the species on a commercial scale is very limited because their seeds exhibit reduced viability and do not tolerate extended storage periods (Mori et al, 2012). No genetic improvement programs have been set up to offer-improved seeds, either for commercial purposes or for the establishment of seed orchards.…”

O que pode ser observado pela alta porcentagem observada de meio-irmãos ( A coancestria dentro de progênie (  =0,134) apresenta valor maior, porem próximo do valor esperado em populações panmíticas (  = 0,125), indicando que há cruzamento entre indivíduos aparentados (MORAES, 2012), demonstrado também pelo parâmetro s m t t .…”

“…Uma hipótese é que essa diferença é decorrente do baixo fluxo gênico entre as populações(MOURA et al, 2009;SILVA et al, 2011). Mesmo apresentando divergência relativamente alta, a maior parte da diversidade está concentrada dentro das populações (83,2%), seguindo o padrão observado em diversas espécies nativas nas quais a maior parte da diversidade ocorre dentro das populações e não entre as populações(KAGEYAMA et al, 2003;MORI et al, 2012).…”
