Acrocomia oilseed palms are endemic to the sub-humid tropical regions of South and Central America. They are considered a promising economic and sustainable alternative to African oil palm, allowing to expand the growing areas of oilseed palms into semi-arid regions. Acrocomia has a specific period of flowering, normally in the first month of the rainy season, and it takes around 12-14 months for the fruits to maturate. Acrocomia is protogynous, as such cross pollination is predominant and the success of reproduction is higher, the more plants flower at the same time. Understanding the differences of flowering patterns between Acrocomia ecotypes is of importance as the time of flowering is crucial for the reproductive success and not the number of female flowers. Even though, flowering patterns were already studied in Acrocomia, this study is the first to assess the flowering pattern and fruit set of contrasting ecotypes of A. totai and A. aculeata grown in the same location.
