Resumo

O objetivo desse artigo foi avaliar a ocorrência do caráter albinismo e estimar a endogamia em uma população de palmito juçara (Euterpe edulis Mart.). Neste contexto, foram avaliadas progênies de polinização livre de 15 (quinze) matrizes da espécie, oriundas de população conservada. No teste de progênies, 13,3% das matrizes apresentaram indivíduos albinos e, portanto, heterozigotas para a característica. Com base na relação mudas albinas/normais, estimou-se uma taxa média de autofecundação de 10,0% e conseqüentemente, um valor de coeficiente de endogamia média de 0,05. Esses valores foram considerados limites para espécies alogâmicas.

Abstract

The aim of present research was to verify the occurrence of albinism character and to estimate the coefficient of endogamy of a juçara palm (Euterpe edulis Mart.) population. On this context, were evaluated fifteen free pollination progenies. The progeny test showed that 13.3% of the seed trees presented albino seedlings and therefore the heterozygous for the characteristic. Based on the ratio between albino and normal seedlings, was estematel that the average tax of self-fertilization was 10.0%. The average value of the endogamy coefficient was 0.05. These values are considered the above of the limits for an alogamous species.
