Physiological ripening of Anadenanthera colubrina (Vellozo) Brenan seeds

Abstract: -The seed physiological maturity knowledgment is critical determine its maximum production and physiological quality. The objective of this study was to determine the ideal time to harvest by evaluating seeds physiological maturity. Seventeen weekly harvests of fruits and seeds from matrices located in the Brazilian city of Botucatu, SP, were performed from May to September 2001. Fruits size and weight, seed water content and dry matter, and germination and emission of primary root were evaluated. Seeds showed… Show more

“…Progressive advancement of maturation in seeds from A0 to A4 resulted in progressive reduction in water content and increase in dry matter content (Figure 2), parameters that are frequently considered as indicators of the point of maturation of seeds (Lazzaroto et al, 2011;Marcos-Filho, 2015;Silva et al, 2015;Pires Neto et al, 2016). Nevertheless, according to the parameters described by Borges et al (2005) for Caesalpinia echinata (that is, seed coat color, dimensions, water content, and dry matter content), seeds of all the ages in this study can be considered as still immature (Figure 2).…”

“…According to Barbosa et al (2015), after zygote formation, the seed moisture content is high (70-80%), with slow dehydration during maturation, followed by intense desiccation. Studies on the physiological maturation stage are of fundamental importance to determine the optimum seed harvesting time, thus guaranteeing maximum yield and high physiological quality (Nogueira et al, 2013;Kaiser et al, 2016;Pires Neto et al, 2016).…”

“…Informações voltadas a melhores condições de propagação são necessários para recomposição de áreas degradadas. Plantios conservacionistas de recuperação investem na produção de mudas florestais nativas, que apresentem boa qualidade fisiológica, selecionadas inclusive por tamanho e massa das sementes (VARELA et al, 2005;NÓBREGA et al, 2008;SANTOS et al, 2012, SILVA et al, 2014MATOS et al, 2015;PIRES NETO et al, 2016).…”
