Reproductive cycle of Pitcairnia flammea Lindl. (Bromeliaceae/Pitcairnioideae) in an insular Atlantic rainforest area in southeastern Brazil
چکیده انگلیسی

We studied for 6 years the reproductive cycle of the bromeliad Pitcairnia flammea in the Atlantic Rainforest of Ilha Grande, an island located in the south of Rio de Janeiro state, southeastern Brazil. We marked 150 adult individuals of the species, for which we monthly observed the occurrence of reproductive characteristics. The phenological attributes were related to environmental factors such as photoperiod, rainfall and temperature. Additionally, we estimated a mortality rate that was related to the rainfall in the area. P. flammea possesses a seasonal reproduction pattern, with a relatively fixed and well-defined time span during the winter dry period; flowering precedes fruiting by approx. 1 month. Due to the occurrence of P. flammea preferably on boulders of river channels and banks mortality of the plants is highest when floods from strong rainfall remove the plants mechanically from their growing places.
