STRUKTUR PRODUKSI GETAH, PERTUMBUHAN DAN KAJIAN FENOTIPIK KEMENYAN (STYRAX SP)
ABSTRACT: Kemenyan tree was
North Sumatera local species that produce high valuable resin and prospective
export comodities. Recently, information about kemenyan resin production,
growth structure and phenotypic studies still not determined yet. The
objectives of this research were : (1) To determine resin production baseline
data, growth structure and growth character related with resin production for
further characterization research and (2). To estimate genetic variable of
resin production through phenotypic characterization. SPSS and Minitab software
were used for determined some variable of research. The result showed that
kemenyan stand on Banuaji IV Village has resin production average as much 192,6
g/tree/yield and right-skewness resin production distribution structure.
Pearson correlation test and multiple linear regression for 11 growth
characters showed 9 characters that correlated with resin production (r:
0.18-0,734) and regression test showed that bark thickness and stem diameter
character can be used as indicator for high resin tree selection. The result on
phenotypic study showed that resin production character has high narrow sense
heritability (h2: 0.55 – 0.60). It indicated that resin production character
dominanly influenced by genetic factor.
