RESUMO: 

O objetivo deste trabalho foi estimar parâmetros genéticos de frutos, sementes e
plântulas de Jatropha ribifolia (Pohl) Baill., subsidiando futuros programas de melhoramento e
conservação genética. Foram selecionadas 20 matrizes da espécie e os frutos coletados em
área de Caatinga, no Município de Jequié - BA / Brasil. Para descrição morfológica foram
observadas características de 50 frutos e 50 sementes. Para germinação foi utilizado o
delineamento experimental inteiramente casualizado com 20 tratamentos (progênie) e três
repetições de 20 sementes. O fruto de J. ribifolia é seco, cápsula loculicida e septicida, endocarpo
lenhoso e deiscência explosiva (autocórica). A semente é oval, endospérmica, de testa lisa, com
diferentes colorações e carúncula presa na parte ventral. O hilo é visível e a rafe bem marcada
longitudinalmente. A germinação é hipógea-criptocotiledonar. O tempo médio para germinação foi
de 10 a 40 dias. As matrizes de J. ribifolia estudadas apresentaram variabilidade genética
significativa para a maioria dos caracteres estudados.

ABSTRACT: 

Genetic parameters of fruits, seeds and seedlings of Jatropha ribifolia (Pohl)
Baill. (Euphorbiaceae). The aim of this study was to estimate genetic parameters of fruits,
seeds and seedlings of Jatropha ribifolia (Pohl) Baill, subsidizing future breeding and genetic
conservation programs. Twenty matrices of the species and the fruits collected in the Caatinga
area in the city of Jequié - BA / Brazil were selected. For morphological description, the features
of 50 fruits and 50 seeds were observed. For germination, completely randomized design was
used with 20 treatments (progeny) and three replicates of 20 seeds. J. ribifolia fruit is dry and has
loculicidal and septicidal capsule, woody endocarp and explosive dehiscence (autochory). The
seed is oval, endospermic and has smooth testa and different colors, with caruncle attached to
the ventral part. The hilum is visible and the raphe is longitudinally marked. Germination is 
hypogealcryptocotylar. The average time for germination was from 10 to 40 days. The matrices of J.
ribifolia showed significant genetic variability for most of the studied traits.
