Influência climática e sazonalidade da fenologia reprodutiva de Qualea parviflora Mart. (Vochysiaceae) em cerradão

The reproduction of cerrado species varies according to climatic conditions. This study describes the reproductive phenology of Qualea parviflora in cerradao, located at Fazenda Fontes do Saber (17°47’12 “S and 50° 57’48” W), Rio Verde, Goias, where 11 individuals were followed between July 2016 and June 2018 to register the intensity of flower bud, anthesis, immature and mature fruits. The evaluations consisted of intensity, seasonality and correlation of the phenophases with the climatic variables. Flower buds and flowers occurred during the rainny season, immature fruits in the rainy and dry period, and maturation in the dry season. All events were seasonal, except for immature fruits. In terms of correlations, only the events of flower buds had strong and significant correlations with rainfall and thermal variations of the study area.
