Regulação hídrica entre frutos e sementes de pau-brasil durante sua maturação

Abstract: RESUMO O pau-brasil, Paubrasilia echinata E.Gagnon, H.C.Lima & G.P.Lewis, é uma das mais importantes espécies vegetais do Brasil. Muitos fatores podem interferir na manutenção da viabilidade e na conservação das sementes, principalmente sua qualidade fisiológica inicial. Entre outros fatores, esta qualidade depende do grau de maturação, sendo importante identificar a maturidade fisiológica com vistas a determinar o melhor momento para a colheita das sementes. O presente trabalho descreve as modificações qu… Show more

“…We observed color changes in both Cenostigma tocantinum fruits and seeds, along with increases in biometric and physiological variables. and 44 DAA, followed by a change to dark green with small light brown spots at 50 DAA and a completely brown color at 60 DAA (Borges et al, 2020). These observed changes are related to the maturation of internal tissues, associated with chlorophyll degradation and synthesis of existing pigments, which determine fruit coloration (Lima et al, 2012).…”
