OCORRÊNCIA DE XILOPÓDIO EM PLANTAS NATIVAS DE IMBUZEIRO

Abstract

This study had the objective of surveying the occurrence of tubers in native imbu (Spondias tuberosa) trees in the Northeast of Brazil. It was carried out in 36 native trees in the Caatinga area of the communities of Sitio Papagaio (Juazeiro-BA), Saco Farm (Jaguarari-BA) and Alto do Angico (Petrolina-PE), from August 2000 to November 2002. In each community, twelve plants were randomly selected for tuber extraction. The following variables were analyzed: plant height, trunk diameter at soil level, canopy diameter, as well as number and total weight of tubers per tree. In the community of Sitio Papagaio, in average, 978.42 tubers per tree were collected, with a total weight of 1731.2 kg. In the community of Saco Farm, in average, 1011.58 tubers were collected, with a total weight of 1820.13 kg. In the community of Alto do Angico, in average, 731.58 tubers per tree were collected, with a total weight of 1370.09 kg. The occurrence of tubers per tree in the communities was, in average, 907.19, with a total weight of 1352.12 kg per tree.
