Breaking the norm: Absence of seed size/seed number trade‐off in Hymanaea stigonocarpa, a tree species from the Brazilian semi‐arid

Plant Species Biology, Volume 40, Issue 5, Page 472-482, September 2025.
Seed size/number trade‐off is a central topic in plant biology as it reflects ecological and evolutionary aspects of the species. Here we report the absence of a trade‐off mass/number of seeds and fruits in a polyspermic plant probably associated to abortion of self‐pollinated pistils and flowers.

Polyphenols, antioxidants, and antimutagenic effects of Copaifera langsdorffii fruit

Food Chemistry, 2016
Copaifera langsdorffii (copaiba) is a Brazilian exotic fruit, poorly studied regarding its bioactive composition. The aim of this study was to determine bioactive compounds, antioxidant and antimutagenic activities of copaiba pulp. The samples were extracted with different solvents in order to analyze polyphenol compounds (Folin Ciocalteau and HPLC-DAD)
