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.

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.

Norlignan from the knot resin of Araucaria angustifolia

Phytochemistry, 1992
Abstract A new norlignan, 2,3-bis-( p -hydroxyphenyl)-2-cyclopentene-1-one, was isolated from the knot resin powder of Araucaria angustifolia . The structure was elucidated by spectroscopic chemical analyses. In addition 4,4′- dihydroxychalcone, cryptoresinol (norlignan), four known lignans and one known norlignan, were isolated for the first time ...

Shade and sapling size influence restoration of Araucaria angustifolia

Journal of Forestry Research, 2020
Toward improving reforestation of Brazilian pine (Araucaria angustifolia), two contrasting sapling sizes in either full sun or in the shade of a mixed plantation and the effect of opening the canopy were evaluated for survival, growth, gas exchange, photosynthetic pigments, and leaf anatomy 18 months after being planted.

Arabinogalactan-proteins from cell suspension cultures of Araucaria angustifolia

Phytochemistry, 2010
Arabinogalactan-proteins (AGPs), found in the culture medium of suspension cells of Araucaria angustifolia grown in plant growth regulator-free and plant growth regulator-containing BM media, BM0 and BM2, respectively, were evaluated quantitatively and qualitatively.

Purification and biological effects of Araucaria angustifolia (Araucariaceae) seed lectin

Biochemical and Biophysical Research Communications, 2006
This paper describes the purification and characterization of a new N-acetyl-d-glucosamine-specific lectin from Araucaria angustifolia (AaL) seeds (Araucariaceae) and its anti-inflammatory and antibacterial activities. AaL was purified using a combination of affinity chromatography on a chitin column and ion exchange chromatography on Sephacel-DEAE ...

Somatic Embryogenesis in Araucaria angustifolia (Bert) O. Ktze

2000
Brazilian pine tree (Araucaria angustifolia), the only native conifer of economic importance in Brazil (Figure 1A), representing the most exploited timber source up to the 70’s (Mattos, 1994; Shimizu and Oliveira, 1981). This tree can provide seed, wood, fiber and resin.
