Estruturas secretoras em órgãos vegetativos e florais de Secondatia densiflora A.DC. (Apocynaceae - Apocynoideae - Odontadenieae)

Abstract: RESUMO:A família Apocynaceae é caracterizada por possuir grande diversidade de estruturas secretoras como idioblastos, coléteres, laticíferos e nectários florais. Este estudo teve por objetivo caracterizar anatomicamente as estruturas secretoras nos órgãos vegetativos e reprodutivos de Secondatia densiflora e identificar as principais classes de compostos químicos nos idioblastos e na secreção dos coléteres vegetativos. Os idioblastos estão distribuídos por todos os órgãos aéreos da planta possuindo conteúdo n… Show more

“…Colleters have been described in at least 60 families of angiosperms (Thomas, 1991), including Apocynaceae (Appezzato-da-Glória and Estelita, 2000; Martins et al, 2013; Ribeiro et al, 2017), Bromeliaceae (Ballego-Campos and Paiva, 2018a,b), Euphorbiaceae (Vitarelli et al, 2015, 2016; Feio et al, 2016; Martins et al, 2016), Fabaceae (Paiva and Machado, 2006; Oliveira and Isaias, 2010), and Rubiaceae (Judkevich et al, 2017; Paiva-Pinheiro et al, 2019). These secretory structures are located in the vegetative and floral buds, and remain in these plant organs throughout their life.…”

“…The colleters studied here can be described as the standard type, present in most Apocynaceae [1,5,6]. Only one layer of secretory epidermal cells is observed in these colleters [1,5,6,11,[18][19][20], which characteristically have thin walls and large vacuoles. However, Tabernaemontana has cells with poorly developed vacuoles, and the periclinal cell walls are thicker than the anticlinal ones [5].…”
