Estimação da taxa de cruzamento da aceroleira com base em dados isoenzimáticos

Abstract: A aceroleira (Malpighia emarginata) é uma espécie da família Malpighiaceae que produz frutos com alto conteúdo de vitamina C. O crescimento da demanda da acerola e de seus derivados causou a procura de variedades melhoradas, para expansão dos plantios comerciais. O objetivo deste trabalho foi obter informações sobre o sistema de cruzamento de um pomar de aceroleiras localizado em Visconde do Rio Branco, MG. Dez famílias oriundas de sementes de polinização natural foram genotipadas usando-se sete locos izoenzim… Show more

“…The maternal fixation index (F̂m) was not different from zero, indicating no inbreeding level of the mother trees. A similar result was found for Malpighia emarginata (Lopes et al 2002). The multilocus outcrossing rate (t̂m) and singlelocus outcrossing rate (t̂s) were equal to 1 (Table 1), indicating that the progenies were originated by outcrossing and that the species is allogamous.…”

“…Em estudos conduzidos por Lopes et al (2002), foram expressos dois locos para peroxidase, quando avaliava a estimativa da taxa de cruzamento em aceroleiras. Mellon (1991) relata que alterações nos níveis de peroxidase e distribuição de isoformas são conhecidas por acompanhar processos de mecanismos de defesa dos hospedeiros a patógenos, como lignificação e suberização.…”

“…Studies suggest that acerola is an allogamous species that developed the specific adaptations needed for plant growth in tropical and subtropical Brazilian regions. Despite its narrow genetic basis, the introduced genotypes present high variability in morphological and quantitative characters as well as for resistance to Meloidogyne incognita (LOPES et al, 2002;ROSSITER et al, 2008).…”
