Morfobiometria de frutos e sementes de <i>Schizolobium amazonicum</i> Huber ex Ducke

Abstract: Resumo -A espécie Shizolobium amazonicum (paricá) vem sendo bastante cultivada nas regiões Norte e Nordeste do Brasil por apresentar rápido crescimento e potencial no setor madeireiro. Diante disto, objetivou-se com o presente estudo avaliar a biometria de sementes e frutos de paricá. Frutos maduros foram coletados na copa de árvores matrizes, escolhidas aleatoriamente e localizadas em áreas urbanas, no mês de dezembro de 2015. A biometria dos frutos e das sementes foi realizada no Laboratório de Tecnologia e … Show more

“…Furthermore, the coefficient of variation of the seed length of the mother plant 5 (São João do Cariri) presented the highest value (12.3%), and the seed width of the mother plant 7 (Esperança) stood out with the lowest value (3.8%) (Table 4). The low standard deviation and coefficient of variation for the assessed characteristics indicate that seed sampling was homogeneous, which is probably related to genetically determined traits for the species (DUTRA et al, 2017a). A study related to biometrics with a species from the family Fabaceae showed low values of standard deviation and coefficient of variation (DUTRA et al, 2017b).…”

“…symmetrifoliolata, indicating a high genetic variability within the population. This may be influenced by biotic and abiotic factors during fruits formation and seeds development (Dutra et al, 2017). Moraes and Alves (2002) affirm that seed size is an important factor, since larger seeds boost the chances of having a successful germination, and increase growth and seedling survival, also producing seedlings that are more vigorous and competitive.…”

“…Diante do exposto, este trabalho teve como objetivo desenvolver e avaliar o desempenho de painéis sanduíche como um possível sistema construtivo utilizando-se lâminas de madeira de Schizolobium amazonicum (paricá) e núcleo de caixa de ovos feita de papelão, colados com adesivos FF e UF. Por ser a madeira de paricá uma espécie nativa das regiões Norte e Nordeste do Brasil, apresenta rápido crescimento (DUTRA et al, 2017), tolerância à baixa fertilidade do solo, facilidade de manejo (SILVA et al, 2020) e baixa incidência de defeitos, o que reflete no aumento do rendimento e na qualidade do compensado (IWAKIRI et al, 2011;MODES et al, 2014). Ainda, a reutilização das caixas de ovos proporciona diminuição da degradação ambiental e valorização do produto final.…”
