PHENOLOGY OF Anacardium occidentale (ANACARDIACEAE) AND ITS RELATIONSHIP WITH CLIMATIC FACTORS

摘要

Phenology of Anacardium occidentale (Anacardiaceae) and its relationship with climatic factor. Anacardium occidentale (Anacardiaceae) is a species of great economic importance for central-west Brazil and few studies have been published on its phenology. This study aimed to describe the reproductive phenology of an A. occidentale population in Montes Claros de Goiás, state of Goiás, Brazil. The following phenophases were recorded monthly in 20 A. occidentale individuals between June 2012 and July 2015: flower bud, anthesis, underripe fruit, and ripe fruit. Data were analyzed using the Fournier index, presence-absence method, Spearman correlation, and circular statistics. Flowering and fruiting were synchronous in the dry season and the two events ended with the onset of the rains, resulting in a negative significant correlation between flowering and rainfall (rs = ?0,73) and a positive significant correlation between fruiting and temperature (rs= 0,7). All reproductive events showed a seasonal pattern.
