Provedor de dados: Acta Scientiarum: Agronomy
Autores: Shibata, Marilia; Coelho, Cileide Maria Medeiros; Araldi, Cristhyane Garcia; Adan, Natalia; Peroni, Nivaldo.
Araucaria angustifolia seeds are the basis for the rural economy in southern Brazil, and the species presents different botanical varieties. The objective of this work was to evaluate the diversity of physical, physiological and biochemical characteristics of Araucaria angustifolia seeds from local varieties: ‘sancti josephi’, ‘angustifolia’, ‘caiova’, and ‘indehiscens’. Seeds were collected from the cities of Painel and Urubici in Santa Catarina State and tested for moisture content, 1000-seed weight, emergence, emergence speed index (ESI), root and shoot length, electrical conductivity, tetrazolium, soluble carbohydrates, and starch content. Among the varieties cited above, the angustifolia variety from Painel displayed a greater 1000-seed weight, ESI,...

Reserve metabolism of stored and germinated Araucaria angustifolia seeds
Provedor de dados: Acta Scientiarum: Agronomy
Autores: Araldi, Cristhyane Garcia; Coelho, Cileide Maria Medeiros.
Germination metabolism of recalcitrant seeds of Araucaria angustifolia is activated in storage, which complicates the seeds conservation and utilization. This study aimed to identify the changes in the reserve metabolites of A. angustifolia seeds throughout storage in order to understand the processes of hydrolysis caused by germination metabolism. Mature seeds were harvested in southern Brazil and stored in an ambient environment and cold chamber conditions. Biochemical analyses were performed for embryos and megagametophytes from seeds stored for 0, 15, 30, 45, and 90 days. Due to seeds being in advanced germination in storage, they were evaluated at 90 days in different early developmental categories: I – seeds with mature embryos, II – seeds with...
