Growth and survival rate of Rhizophora mucronata viviparous seedlings using riley encasement method (rem) at Kampung Pengkalan Gelap, Setiu, Terengganu

Abstract

A study was conducted in mangrove nursery in Kampung Pengkalan Gelap, Setiu, Terengganu to determine the growth of three months old Rhizophora mucronata seedlings in two different planting method that are Ridley Encasement Method and conventional method. The objective of this study is to study the survival rate and the initial growth of the Rhizophora mucronata seedlings. This study also wants to compare the growth and the survival rate of Rhizophora mucronata seedlings using the Ridley Encasement Method and conventional method. The height of the seedling was measured and the numbers of the seedling was counted twice in a month until the thirteen weeks. The seedlings that planted using conventional method showed the increased in height and number of leaves through the days compare to the Ridley encasement method that fluctuated throughout the observation days. Eventually, the seedlings survival rate planted in Ridley Encasement Method is higher than conventional method. It is suggest that to experimental Ridley Encasement method to the high energy shoreline that exposed to high wave to test the full potential of this method to establish new mangrove area in preventing coastal area erosion.
