- Abstract
Ceriops decandra is a shrubby mangrove species, which shows budding, flowering and fruiting continuously throughout the year. It is an obligate outcrosser and fruit set occurs only in the presence of pollinators. The flowers have a simple pollination mechanism and are adapted for pollination during daytime by Nomia bees and Odynerus wasps. The plant shows a high per cent of bud and flower abortion. Fruit abortion is absent, but only one ovule produces seeds in all flowers. Abortion at different stages of the reproductive unit is considered to be a strategy to adjust the available maternal resources to the growing fruits and seedlings. The seedling characteristics suggest true vivipary, but the seedlings stay on the maternal parent for a short period, which is a characteristic of cryptoviviparous mangrove species. Viviparous growth is considered to be an adaptive strategy for seedlings to overcome the harsh mangrove environment prior to establishment.
