“…Contrasting with our study, Fava & Albuquerque (2011) affirmed that the study species exhibits seed dormancy. Genetic factors and environmental factors may affect seed germination by influencing seed viability and quality within same species from different areas (Soler-Guilhen et al 2020). The initial moisture content of the pyrenes was ~10%, with similar results of 10% (Fabri 2018) and 16.6% (Masetto et al 2012) for the same species.…”

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.

“…2a), indicating a high germination percentage, with no primary dormancy type, contrary to previous studies (Fava and Albuquerque 2011). Genetic factors may affect seed germination by influencing seed viability and quality in the same specie from different areas (Soler-Guilhen et al 2020). Lack of dormancy in C. alba seeds can warrant recruitment in the Pantanal wetlands where seeds are subjected to flooding conditions, demonstrated by a rapid flush of seedling emergence in the post-flood environment (Bao et al 2018).…”

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 .

“…This, in part, can also be attributed to A. murumuru seeds. In Euterpe edulis Mart., the existence of genetic variability in germination percentage and speed between genotypes indicated the possibility of selection for these characteristics (Soler-Guilhen et al, 2020).…”

GERMINATION AND POST-SEMINAL DEVELOPMENT OF Astrocaryum murumuru MART. PROGENIES

2022

View full text Add to dashboard Cite

Astrocaryum murumuru is a palm tree whose seeds have been exploited in an extractive way by traditional populations in the Amazon, providing raw material to the cosmetic industry, with lack of information about its propagation. Thus, the aim of this study was to characterize seeds, germination, and seedling development of different A murumuru progenies. Seeds from six racemes from different plants were used, which were physically characterized and sown in a completely randomized design, with six treatments (progenies) and four replicates. Description, illustration, and quantification of the mean time of the different seedling stages were performed. On average, the diameter, length, and mass of soaked seeds were 17.1 ± 1.2 mm, 28.4 ± 5.8 mm, and 3.3 ± 0.6 g, respectively. A. murumuru germination is of adjacent type, with the cotyledon sheath developing next to the seed. Seedling development took an average of 46 ± 28 days to reach the germinative bud stage and 225 ± 38 days to reach the third expanded eophyll stage. The emergence of the first cataphyll (normal seedling) ranged from 12 to 73% among progenies, which occurred in an average time of 73 ± 29 days. There is a need to improve the processing of A. murumuru seeds aiming to reduce seed loss during this process, as well as studies on seed dormancy. Progenies showed variation regarding the physical and physiological characteristics of seeds and seedlings. Germination and seedling development can be considered slow, with variable times among progenies.
