Effect of Inundation Degree on the Growth of Rhizophora mucronata Lamk. to Different Seedling Age at the Mangrove Ecotourism Area, Angke Kapuk, North Jakarta

ABSTRACT

Increasing of CO2 consentration in the atmosfer has caused to global climate change. It can be used to indicate of sea level rise. In this phenomenon, mangroves have high tolerance towards the sea level rise due to its high salinity. Rhizophora mucronata represents the type of mangrove plant species that has an ability to grow at the higher tidal area than Avicennia marina. Research was done on March to June 2011 at the Mangrove Ecotourism of Angke Kapuk, North Jakarta. The method was explored by using randomize block design with three replication (blocks of seedling age 28 weeks, 12 weeks and 8 weeks) and three treatments (inundation of about up to
50% stem length, inundation of close to under canopy, inundation at root neck). Primary data
consisted of height, diameter, quantity of leaves, quantity of internodes, length of internodes and biomass, meanwhile secondary data consisted of climatology data. The data were analised by SAS 9.1.3 Portable. Seedling age 28 of weeks with inundated of about up to 50% stem length was significant on the growth of R. mucronata than other treatments. Based on the research result, R. mucronata growth indicated average around 7.75 mm of stem diameter, 454.21 mm of stem height,
7 leaves, 5.33 mm length of internodes, biomass (6.18 gram of stem and 9.59 gram of leaves) and
13.48 mm per weeks of current weekly stem height.
