摘要
the objective of this study was to estimate the richness and the diversity of fruit tree species cultivated in boa vista%26apos;s home gardens, as well as to determine what species the local urban population prefers. two neighborhoods that originated during the city%26apos;s expansion in 1982 were sampled: (1) best - bairro dos estados (north zone) and (2) basa - bairro asa branca (west zone). seven hundred and twenty-two home gardens were surveyed in best (march 6 to 22, 2004), and 339 in basa (april 7 to july 1, 2004). thirty-six species (19 botanical families) were observed in best, and 37 (20 families) in basa, totaling 43 species (20 families). thirty species (69.8%) in 19 families (95%) occurred in both neighborhoods, suggesting common fruit preferences. the three largest indices of preference value (ivp) were coconut (cocos nucifera l. - best: 19.4% and basa: 20.5%), mango (mangifera indica l. - best: 14.9% and basa: 22.5%) and rose-apple (syzygium malaccence (l.) merr. %26 l.m. perry - best: 10.5% and basa: 10.1%). all of them are exotic (originating in southeast asia) and together had ivps of 44.9% (best) and 53.0% (basa). these results suggest that the cultivation of fruit trees in the home gardens of boa vista shows a pattern that concentrates choices in a few non-amazonian species that are traditionally preferred because of their successful fruit production.
