Use of low temperature for the conservation of seeds of Araucaria angustifolia (Bert.) O. Kuntze



Use of low temperature for the conservation of seeds of Araucaria angustifolia (Bert.) O. Kuntze



II Simposio sobre avances en la produccion de semillas forestales en America Latina: Memorias, Santo Domingo, Re ica Dominicana, 18-22 de octubre 1999: 215-218



A. angustifolia seeds from San Antonio, province of Misiores, Argentina, were dipped in captan (20 g/10 litres water) for 10 minutes, and then covered with polyethylene (PE) or ethyl vinyl acetate (EVA). Seeds were stored for 360 days at 0, 4 and 10 degrees C. Data are presented on seed weight losses and seed germination rates after 2, 4, 6, 8, 10 and 12 months. Highest seed germination rates were obtained after 4-6 months of storage (independent of temperature).
