PHENOLOGY OF <i>Aniba parviflora</i> (MEISN.) MEZ. IN A REGION OF PARÁ STATE, BRAZIL

The aim of this work was to study the phenology of Aniba parviflora (Meisn.) Mez. The study was developed in Curauá experimental farm located in Curuá-Una highway in Santarém - Pará. The record of phenophases was conducted on 15 trees and the monitoring period lasted 44 months, between May / 2011 to December / 2014 being the headquarters monitored monthly. The evaluated phenophases were flowering season, fructification and leaf change. In phenological evaluation was recorded the intensity of each event and synchrony. The influence of climatic factors on the phenological phases was analyzed using the Spearman correlation coefficient (rs). The flowering phenology was more intense in the rainy season, with flower buds showing significant correlation with rainfall (rs=0.399), mean temperature (rs=-0.448), maximum temperature (rs=-0.440) and humidity (rs=0.472) and flowers open with an average temperature (rs=-0.354) and humidity (rs=0.397). The phenophase green fruits showed peaks at both the stations and there was no significance to climate variables. Considering the mature fruit, the highest intensities were in the dry season, with significant correlation with rainfall (rs=-0.5894), average temperature (rs=0.755), maximum temperature (rs=0.700) and humidity (rs=-0.771). In the dry season occurred the greatest manifestations of phenophases little leaf / leafless and significant correlation with average temperature (rs=-0.528), maximum temperature (rs=-0.579) and humidity (rs=-0.543). In the rainy season occurred the highest peaks of old leaves. There was a correlation between old leaves with a mean temperature (rs=-0.523), maximum temperature (rs=-0.585) and humidity (rs=- 0.470). The major and minor peaks phenophase new leaves were observed at both stations. There was a significant correlation with rainfall (rs=-0.326), average temperature (rs=0.304) and maximum temperature (rs =0.319) and phenophase new leaves. Phenophases that showed high synchrony were the flower buds (68%), green fruits (82%), new leaves (80%) and old leaves (100%). The species can be considered evergreen with subanual reproductive pattern. Keywords: Phenophases; % of Fournier; macacaporanga; synchrony.
