Palm seeds are known for displaying dormancy and a thick endocarp that delays germination and embryo growth, but water treatments may accelerate their germination process. Additionally, ex-situ conservation of arecaceae species may cause loss of seed viability over time. Data on seed dormancy and storage have been neglected for many native palm species in Brazil. Therefore, we investigated the effect of water treatments and one-year storage on the germination of Copernicia alba Morong, a palm tree from the Brazilian Pantanal wetland. Fresh and stored pyrenes were immersed in water (at room temperature for 24, 48, and 72h) and in hot water (~75°C for 5 and 10-min). Fresh pyrenes germinated up to 84% in control, reaching 100% after water immersion for 48 and 72h. One-year storage reduced germination by almost 50%, but water immersion slightly increased the germination of stored pyrenes. Hot water decreased germination for both fresh and stored pyrenes. Seeds of C. alba may be classified as orthodox seed storage behavior. Taken all together, water treatments at room temperature improved the germination of the pyrenes. In contrast, long-term seed storage and hot-water treatments may jeopardize germination.

“…2d). Likewise, hot water treatments jeopardized the germination of Euterpe oleracea seeds from the Amazon rainforest (Bovi and Cardoso 1976). Thermal shock also did not promote the seed dormancy of Acrocomia aculeata (macaw palm) but rather caused high seed deterioration rates (Rodrigues-Junior et al, 2016).…”

Copernicia alba (Morong ex Morong & Britton) is a palm tree native to tropical and subtropical climates, commonly named “carandá”, that often forms monodominant populations in the Pantanal wetland in Brazil. Currently, the knowledge of the seed germination behavior of C. alba is still limited, as well as seed viability in ex-situ conservation under laboratory conditions. Hence, this study investigated the effect of water treatments and a one-year storage period (at 19°C under a relative humidity of 45%) on its germination. We subjected fresh and stored seeds to immersion in water at room temperature (~25°C) for 24, 48, and 72 h; and hot water (~75°C) for 5 min and 10 min. The results showed that seeds do not have primary dormancy, with fresh seeds germinating 84% in the control. Additionally, fresh seeds had a significant increase in germination percentage (reaching 100%) and faster germination times after immersion in water for 48 and 72 h. On the other hand, hot water treatments decreased germination for both fresh and stored seeds. One year of storage reduced the germination capacity by almost 50%. We concluded that seeds of C. alba may be easily germinated under laboratory conditions for seedling production, and water immersion at room temperature can improve the germination of fresh seeds. However, long-term seed storage and hot-water treatments may jeopardize germination. Future studies should further investigate ex-situ conservation of seed of C. alba under extended periods, considering seed desiccation and alternative storage conditions, to improve seed conservation techniques .
