| Summary: | The reproductive phenology of two mangrove tree species, Rhizophora apiculata and Rhizophora mucronata, were observed
monthly for one complete annual cycle from March 2010 until February 2011 at Sungai Pulai Forest Reserve (FR). The
objectives of this study were to identify and compare the reproductive phenological patterns of the two species, to determine
the duration of flowering and fruiting development, to investigate the percentage of successfulness for each species, and to
look at the relationship between rainfall and temperature with reproductive phenological patterns of the two Rhizophora
species. Results revealed that both species produced all reproductive units (flower bud, open flower, and fruit) throughout
the study period. The flower bud season for R. apiculata was from November until May whilst R. mucronata was from
November until April. The flowering season was from June until August for R. apiculata and January until May for R.
mucronata. The fruiting season of R. apiculata was from July until January while March until May for R. mucronata.
Development from young flower buds to mature propagules took about 14 to 16 months in R. apiculata. Results showed
that 7.3% flower buds of R. apiculata gave rise to open flowers and only 1.4% were fertilized. The production of R. mucronata
flower buds was significantly (p< 0.05) inversely correlated with the total monthly rainfall and its fruits production was
positively correlated with the mean temperature. |
