The phenological parameters of five mangrove
species such as Sundri (Heritiera fomes),
Gewa (Excoecaria agallocha), Kankra (Bruguiera sexangula), Goran (Ceriops decandra) and Passur (Xylocarpus mekongensis) were studied
during 2005 - 2014 at three ecological zones of the Sundarbans of Bangladesh.
Appropriate annual time for leaf emergence, leaf shedding, flowering, fruiting
and dropping time of fruit/ propagules were determined. The phenological
parameters of E. agallocha, B. sexangula, C. decandra and X.
mekongensis were found almost same in three salinity zones. It has been
established that the duration of flowering, fruiting and dropping time of H. fomes was shorter in the less saline
zone but longer in the strongly saline zone.
