“…stands out, being widely distributed in the region, usually found along riverbanks or in periodically fl ooded areas, although occasionally occurring at 900 m altitude, on slopes of the eastern Andes (Henderson et al, 1995). Frequently, it has hyperdominance, reaching 325 plants per hectare (Steege et al, 2013), which favors extractivism due to the logistical ease for fruit collection (Cruz et al, 2017). Its seeds have great potential for use in the cosmetic, food, emulsifi er, soap, surfactant, and biodiesel industries, due to their high content of fatty acids, especially lauric (55%) and myristic (31%) acids (Almeida et al, 2008).…”

“…This activity has been considered important for being a complementary alternative to income for these communities, in addition to favoring the conservation of the species and/or local biodiversity (Costa and Simões, 2013). Although extracted products are well accepted in the market, it is necessary to improve processing techniques to reduce losses that occur during the oil extraction process (Cruz et al, 2017). In addition, the production seasonality and the high cost of distribution logistics make it diffi cult to estimate the amounts of oil to be produced and, therefore, the meeting of demands (Vidal et al, 2021).…”

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

2022

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.
