Citogenética de Piper hispidinervum e Piper aduncum

Abstract: Resumo -O objetivo deste trabalho foi detectar diferenças entre duas espécies de pimenta-longa por meio de análise de cariótipos. Foram analisados cinco acessos de Piper hispidinervum (Piperaceae) C. DC. e Piper aduncum L. (Piperaceae) pertencentes à coleção de germoplasma da Embrapa Acre, utilizando-se o método de esmagamento e coloração de Feulgen. As duas espécies apresentaram número cromossômico 2n = 24 e cromossomos pequenos e metacêntricos com comprimento médio de 1,38 µm em P. hispidinervum e 1,32 µm em… Show more

According to those authors, this group might be a primitive group from which the x = 13 lineage has evolved.…”
