Morphometry of the fruits of Genipa americana (Rubiaceae): a case study from the southern coast of Bahia, Brazil

Abstract

We conducted a study to assess the morphometric attributes of Genipa americana fruit, and their relationship with variations in elevation and distances between sampling sites on the southern coast of Bahia, Brazil. Eight fruit were used per sampling site (ten sites; n = 80). Mantel’s test revealed that the spatial distance between sample sites, and elevation of all sampling sites were significantly correlated with the similarities found in fruit diameter (DF), fruit length (FL), and fresh fruit mass (FFM), but the spatial distance between sites, independently of the elevation, was only correlated with the number of seeds per fruit (NSF) and total fresh mass of seeds per fruit (FMSF). The morphometric attributes of fruits, and their associated relationships with elevation and distance between sampling sites are demonstrated.
