Phenological and reproductive aspects of Vriesa incurvata Gaudich (Bromeliaceae) - DOI: 10.4025/actascibiolsci.v28i2.1011

Abstract

The results of phenological monitoring and quantification of seed production of Vriesa incurvata Gaudich were presented. The study was carried out in Rio da Onça State Park, (Matinhos, Paraná State, Brazil, 25 ° 50´S and 48° 30´W). The occurrence of flowering, fructification and dispersion phases, and sprouts were registered. In parallel, 30 inflorescences were collected in two dates (August, 2003 and 2004) in order to evaluated the size, number of developed fruits and amount of seeds. The flowering happened from January to February, with the highest level observed in April and May. Fructification and the emission of clone sprouts began in April and persisted through June and July. Dispersal started on August and continued until December. There were positive correlations between the phenophases of inflorescence emission to temperature and photoperiod. The fructification and emission of clone sprouts presented negative correlation with photoperiod during monitoring.
