Abstract

Germination of half-sib progenies of Euterpe oleracea Mart., promising for palm heart production were studied. A cluster with seeds of each progenie was selected at Embrapa Experimental Sation placed in Eastern Amazonia. Fruits were immersed in warm water and the chosen seeds were sown immediately. Randomized blocks design with 25 treatments (progenies), three repetitions and parcels of 100 seeds were utilized. Evaluation of the following characters were made: days for beginning (IG) and end (FG), average time (TM) and percentage (PG) of germination. Progenies presented genetic differences for germination characters. Beginning of germination (IG) and the average time (TM) showed the biggest estimates of heritability related to b index.
