Publisher: 1990Subject(s): BACTRIS GASIPAES | REGENERACION NATURAL | BRASIL | BACTRIS GASIPAES | NATURAL REGENERATION | BRAZIL | BACTRIS GASIPAES | REGENERATION NATURELLE | BRESIL In: Acta Amazónica (Brasil) (no.20) p. 399-403Summary: Numerous pejibaye plants were evaluated in 12 year old second growth on an abandoned farm to determine the extent of natural regeneration. Adult plants with crowns above the canopy produce fruit. Fruits are predated by man and seeds by rodents. Lateral shoots grow well with enough light or show leaf etiolation and reduced number in shade. Two seedlings were found, with low leaf number, etiolated petioles and low leaf area, suggesting extremely slow growth in shade. Reproduction appears to depend upon natural or man-madeclearings, the former of insufficient duration to permit natural regeneration. This, combined with other modifications, confirms pejibaye's status as a full domesticate.
