“…Even though the experiment was conducted under atypical conditions, with the isolation of embryos in culture medium, it can be inferred that this might be a natural property of this species. These findings are corroborated by those of Schlindwein et al (2013), who observed, in experiments with diaspores of B. odorata, an average of more than one emerged seedling per sown diaspore.…”

“…seeds is slow and they typically present low viability (Geymonat & Rocha 2009). Although only few methods exist to overcome the dormancy of these seeds, these extant methods are laborious and time consuming (Carpenter 1988, Fior et al 2011, Schlindwein et al 2013, Hoff mann et al 2014. According to Orozco-Segovia et al (2003) and Henderson (2006), the diaspore structure and the germination process in palm trees are quite peculiar.…”

Butia odorata (Barb. Rodr.) Noblick is a palm species that has potential for economic and environmental applications. The aim of this study was to evaluate the seed viability of a B. odorata population using two methods, as well as the water content at three ripening stages, the average number of fruits per infructescence, and the thousand-diaspore weight. Fruits and seeds were analyzed from the beginning of ripening stage to the partial dehiscence stage. The percentage humidity of the diaspores collected from the beginning of ripening to the dehiscence of fruits ranged between 16.8% and 19.8%. However, one week after pulping, when the seeds were maintained in a dry and ventilated environment, the water content decreased to 11.06%, regardless of the fruit ripening stage. The average mass of 1000 diaspores was 1.9 kg, with variation among the mother plants. We recorded an average of 860 fruits per infructescence and around 1,570 viable seeds. Around 2% of these seeds lacked an embryo. The viability was 83%.

“…In a study with B. odorata kernels, Schlindwein et al [15] reported that the combination between periods of high humidity and temperature (90% moisture + 21 days at 40°C + 30°C) associated with pre-drying (24 hours), which favors germination (70.0%), because of the diaspores drying and hydration cycles are related to seedlings surpassing dormancy, which promotes occurrence of physiological changes in B. odorata seeds, but does not significantly reduce the average germination time (39 days). Therefore, this pre-storage of the kernels during the period of 30 days in a chamber with 90% of humidity does not alter the germination.…”

“…B. odorata is propagated exclusively by seeds, which present dormancy and uneven germination results in poor seedling production, thus hindering the effectiveness of conservation. Fior et al (2011) and Schlindwein et al (2013) suggested several alternatives to overcome dormancy, as opening the seed embryonic cavity or through dry and warm stratifi cation. However, these methods are labor-demanding and require specifi c conditions.…”

Butia odorata is a palm native to southern Brazil and Uruguay, not domesticated, much appreciated for its fruits and economic potential. However, the extractivism and the diffi culty of propagation have led to the decline of natural populations. The objective of this work was to prove the possibility of induction of somatic embryogenesis in B. odorata. Mature zygotic embryos were induced in two media, MS and Y3, combined with auxin 2,4-D and picloram in fi ve concentrations (2,4-D: 0, 361.99, 452.49, 542.99 and 633.48 μM/L, picloram: 0, 50, 150, 300 and 450 μM/L). The results promising during induction with the formation of embryogenic calli and somatic embryos, however the regeneration of them was not effi cient, this may be due to the occurrence of somatic embryos fused during its development. The roots were formed, but the aerial part remained molten, not completing its development. Auxin picloram and Y3 medium provided the most adequate conditions for calogenesis, formation of embryogenic callus and somatic embryos, with concentrations of 150, 300 and 450 μM/L. This is the fi rst description of somatic embryogenesis in B. odorata that will serve as the basis for future research and adjustments of the methodology proposed here.
