Rodent handling of Araucaria araucana seeds

Austral Ecology, 2012
AbstractIn an intermast year of very low seed production, we studied seed handling in an Araucaria araucana (Araucariaceae) forest in Neuquén Province, Argentina. Rodents identified in 844 photographs from automatic cameras removed 589 seeds marked with small embedded magnets. Within 12 days of removal, 460 were recovered using a magnetic field locator;

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 ...

Seed development of Araucaria angustifolia: plant hormones and germinability in 2 years of seeds production

New Forests, 2021
During seed development, plant hormones are involved in processes such as the accumulation of reserves, cellular activity and physiological responses. The present study aimed to analyze levels of abscisic acid, gibberellins, auxins, salicylic acid and their role in the physiological responses during development of A.

SEEDS AND EMBRYOS OF ARAUCARIA MIRABILIS

American Journal of Botany, 1975
Seeds and embryos contained within the silicified ovuliferous cone Araucaria mirabilis from the Cerro Cuadrado petrified forest are described. One wingless seed, 0.8–1.3 cm in length and 0.2–0.6 cm in width, is embedded in each ovuliferous scale. Seeds show a three‐layered integument and a prominent wavy nucellus which is attached basally to the ...

Seed Development in Araucaria Juss

Australian Journal of Botany, 1983
The development of the seed coat, seed wing and food reserve tissue of the female gametophyte was studied in four species of Araucaria: A. cunninghamii, A, heterophylla, A. bidwillii and A. hunsteinii. The means of seed dispersal in each of these species were also recorded.

Sweet endosperm detected in Araucaria angustifolia (Bertol.) O. Kuntze seeds

Genetic Resources and Crop Evolution, 2020
We discovered an Araucaria angustifolia (Bertol.) O. Kuntze with sweet seeds, this is the first description and seems to be an isolated case. We aimed with this work to characterize this sweet seed and compare them with the typical one. We found that the sweet seeds presented 763% more reducing sugars, 466% more total sugar, and 54.8% lower starch ...

Chemical Composition and Glycemic Index of Brazilian Pine (Araucaria angustifolia) Seeds

Journal of Agricultural and Food Chemistry, 2004
The seeds of Parana pine (Araucaria brasiliensis syn. Araucaria angustifolia), named pinhão, are consumed after cooking and posterior dehulling, or they are used to prepare a flour employed in regional dishes. Native people that live in the South of Brazil usually consume baked pinhão. As a result of cooking, the white seeds become brown on the surface

Seed predation ofAraucaria angustifolia(Araucariaceae) by small rodents in two areas with contrasting seed densities in the BrazilianAraucariaforest

Journal of Natural History, 2011
We investigated the effects of variation in seed density on small-rodent predation of Araucaria angustifolia seeds. Seed removal experiments were conducted simultaneously in two contrasting stands (seed-poor – planted with the slash pine Pinus elliottii and seed-rich – planted with A. angustifolia) outside the seed production period and also during the

Adsorption isotherms of pinhão (Araucaria angustifolia seeds) starch and thermodynamic analysis

Journal of Food Engineering, 2010
Abstract The seeds of Araucaria angustifolia, commonly known as pinhao, are widely consumed in both Southern and Southeastern Brazil due to their high nutritious value comprised basically by starch. The literature on the technological aspects of this seed is still very scarce.
