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

Zusammenfassung: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. Resumo Nós conduzimos um estudo com o objetivo de acessar os atributos morfométricos de frutos de Genipa americana e suas semelhanças associadas a elevação e distância entre locais de coleta no Litoral Sul da Bahia, Brasil. Foram utilizados oito frutos por local de amostragem (dez locais; n = 80). O teste de Mantel revelou que a distância espacial e a elevação de todos os locais de amostragem estavam significativamente correlacionadas com as semelhanças encontradas no diâmetro do fruto (DF), comprimento do fruto (FL) e massa fresca do fruto (FFM), mas a distância espacial apenas se correlacionou com o número de sementes por fruto (NSF) e a massa fresca total de sementes por fruto (FMSF). Foi demonstrado que os atributos morfométricos de frutos e suas semelhanças associadas na elevação e distância entre os locais de amostragem.
