Development of mucilage cells of Araucaria angustifolia (Araucariaceae)

Protoplasma, 2008
The roles of mucilage cells were investigated through morphological and cytological analysis during leaf development in young Araucaria angustifolia plants. Differentiation began in leaf primordia in the shoot apex, when the young cells underwent a greater increase in volume in comparison with other mesophyll cells.

Bioenergetic use of Araucaria angustifolia branches

Biomass and Bioenergy, 2020
Abstract The aim of this study was to physically, chemically and energetically characterize A. angustifolia branches of different dimensions and to compare them with the values described in literature. Thus, a total of 30 branches from 15 adult native trees were divided into three treatments according to the following base diameters: (S) less than 0 ...

Immunoanalysis of dehydrins in Araucaria angustifolia embryos

Protoplasma, 2012
The aim of this study was to describe the dehydrin content of mature Araucaria angustifolia embryos, a species of endangered and economically important conifers, native to southern Brazil, northeastern Argentina, and eastern Paraguay. The A. angustifolia seeds have been categorized as recalcitrant. Dehydrins were studied by western blot analysis and in

Diversity of Secondary Metabolites of Araucaria Seed (Araucaria angustifolia (Bert.) O. Ktze) Residues

Ensaios e Ciência C Biológicas Agrárias e da Saúde, 2022
A semente da Araucaria angustifolia (Bert.) O. Ktze é conhecida como pinhão e é considerada um alimento de alto valor nutricional. No consumo do pinhão, seu tegumento é descartado, gerando um resíduo que apresenta um processo lento de decomposição. Esse material é composto por três camadas de tecido: camada interna (endotesta), camada intermediária ...

Somatic Embryogenesis in Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae)

2016
This chapter deals with the features of somatic embryogenesis (SE) in Araucaria angustifolia, an endangered and native conifer from south Brazil. In this species SE includes the induction and proliferation of embryogenic cultures composed of pro-embryogenic masses (PEMs), which precede somatic embryos development. A.
