Abstract:
This study is about replanting of Rhizophora apicu/ata propagules by using
two different planting methods which are conventional method and Riley Encasement
Method (REM). Conventional method is a method which propagule is directly planted
into the soil without any encasement while REM is a method of propagules planted
within encasement to help the propagule to survive. The objectives of this project are
to study and compare the survival and initial growth rate (plumule height and average
number of leaves) of R.apiculata propagules based on the two methods.
Based on the result, there is significant difference between both methods in
initial growth of plumule height and average number of leaves. There are also weaker
correlations between the plumule height and average number of leaves with physical
parameter. Besides that, there are also high survival rate of propagules in REM
compared to conventional method.
In conclusion, by using REM in propagules replanting will help in survival of
the propagules besides increased the growth rate compared to using conventional
method. It is also suggested that, there should be longer period on study the planting
method of propagules in conventional and REM in order to observe the growth rate.
Besides that, further study should be done in other species of mangroves to be applied
in REM. This will then help in reforestation of mangroves.
