Posição da semente na semeadura e tipo de substrato sobre a emergência e crescimento de plântulas de <i>Schizolobium parahyba</i> (Vell.) S.F. Blake

Abstract: RESUMOA germinação rápida e uniforme das sementes, seguida por pronta emergência das plântulas são características altamente desejáveis na formação de mudas. O objetivo deste trabalho foi identificar a posição da semente na semeadura e o substrato mais adequado ao processo de germinação e crescimento de plântulas de Schizolobium parahyba (Vell.) S.F. Blake. As sementes foram colocadas para germinar nas seguintes posições em relação ao fundo do sulco no substrato: semente com o hilo voltado para cima, com o hil… Show more

“…The oil extracted from its seeds has been industrialized by the pharmaceutical and cosmetic sectors, which has increased the demand for seedlings for planting (Follegatti-Romero et al, 2009;Gutiérrez et al, 2011;Ruiz et al, 2013). For the production of seedlings of a certain species, it is important to identify temperatures and substrates that favor their germination and growth (Martins et al, 2012). Temperature acts on the speed of water absorption and biochemical reactions that determine the entire process of germination, and the substrate is also important, because its chemical composition, texture and structure influence the availability of water, oxygen, light and nutrients (Lima et al, 2010;Weitbrecht et al, 2011;Silva et al, 2014).…”

“…Os resultados obtidos para a invasora Cryptostegia madagascariensis concordam com os encontrados por Freire et al (2014) e Martins et al (2012) para as espécies Bauhinia divaricata L. e Schizolobium parahyba (Vell.) S.F.…”

“…Os valores das médias do IVE não diferiram estatisticamente entre si para as profundidades 1,0, 2,0 e 3,0 cm, com constatação do menor valor quando as sementes foram semeadas a 4,0 cm de profundidade. Martins et al (2012), trabalhando com diferentes posições e substratos em sementes de Schizolobium parahyba (Vell.) S.F.…”
