Aspectos biométricos, morfoanatômicos e histoquímicos do pirênio de Bactris maraja (Arecaceae)

Abstract: ResumoBactris maraja (marajá) é uma palmeira frequente nas margens de lagos e igarapés amazônicos, cujos frutos comestíveis são consumidos pelo homem e pela fauna. Os estudos morfoanatômicos das estruturas reprodutivas podem contribuir com informações que subsidiarão estudos taxonômicos, fisiológicos e ecológicos. O objetivo deste estudo foi determinar características biométricas e morfoanatômicas do pirênio, bem como característi-cas histoquímicas da semente. Frutos maduros foram coletados e foram determinada… Show more

“…The protein bodies found within the endosperm cells of palm trees may be related to the accumulation of hydrolytic proteins, activated during the mobilization of the endosperm reserves. Similarly, the occurrence of pectins within the endosperm cells of açaí have also been reported for other palm species (Moura et al 2010;Nazário et al 2013;Rodrigues et al 2015;Mazzottini-dos-Santos et al 2017. Pectins are structural polysaccharides that usually compose the cell wall.…”

“…In comparison with the tucum, the pyrene (Bactris maraja Mart.) weights almost three times less [22]. The almond weight of tucum-do-Pantanal corresponds to 60.32% and its endocarp to 39.68% (Figure 1).…”

“…Isto já era esperado considerando que estas espécies estão em ambiente natural na Caatinga nordestina. No entanto, quando esta variação é muito baixa pressupõe-se que as matrizes estão presentes em ambiente com vegetação primária (RODRIGUES et al, 2015).…”
