PENGARUH SALINITAS TERHADAP PERTUMBUHAN DAN PERKEMBANGAN AKAR SEMAI MANGROVE RHIZOPHORA APICULATA BLUME
ABSTRACT: Rhizophora apiculata
is easy species to be found and widely distributed. The purpose this research
is to know the best concentration of salinity for growing seedlings of mangrove
as refrence to rehabilitate mangrove forest. Effect of salinity on the growth
and root development in mangrove Rhizophora apiculata Blume seedlings at
Greenhouse Faculty of Agriculture and Laboratory of Ecology, University of
Sumatera Utara from May 2015 until October 2015. Five level concentration of
salinity was used namely 0%, 0,5%, 1,5%, 2%, and 3% with ten of repeatation.
The research measured the parameters of height seedlings, diameter, leaves
thickness, wide of leaves, primary root, lateral root, long of primary root,
long of lateral root, diameter of primary root, diameter of lateral root, water
content of shoot, water content of root, and shoot ratio. We found that the
best growing Rhizophora apiculata seedlings was at 0,5% salinity level.
