PERKECAMBAHAN BENIH DAN PERTUMBUHAN SEMAI TANJUNG (MIMUSOPS ELENGI L.) PADA BERBAGAI TEKNIK SKARIFIKASI DAN MEDIA TUMBUH
ABSTRACT: Cape (Mimusops
elengi L.) treeis one of tree species that grows quickly and adapts easily in
tropical area. But, the cape tree needs a longer time to get germination
becuase of its hard seed skin. Therefore, it needs scarification or earlier
treatment in order to fasten the seed germination. The objective of the reseach
was to find out both of seed germination and seedling growth of the cape tree
(Mimusops elengi L) on some scarification techniques and growing medium. The
research was conducted on June to August 2015 in Permanent Seedling of BPDAS
Palu – Poso, Tadulako University, Palu. The soil analysis was conducted in
Agronomy Laboratory, Forestry Faculty, Tadulako University. The research
applied Factorial Pattern of Complete Randomized Design that consisted of 2
factors and repeated 5 times. The first factor was scarification technique that
without scarification or control (S0), seed was submerged in cool water for
3x24 hours (S1), submerged in hot water with early temperature 100°C for 15
minutes (S2), and it submerged with KNO3 0,5% for 10 hours (S3). The second
factor was growing medium, soil (M0) and soil mixed with hull of rice charcoal
(M1), so there were 8 treatments combination, they were S0M0, S0M1, S1M0, S1M1,
S2M0, S2M1, S3M0, and S3M1. The result of the research showed that treatment
combination of seed scarification that submerged with KNO3 0,5 % for 10 hours
by using soil growing medium (S3M0) gave the highest result on percentage
parameter of seed germination of 81,1%, the speed of germinationwas 25,44 days,
and seedling wet weight was 0,562 gram. The treatment combination of seed that
submerged in cool water for 3x24 hours by using growing medium soil mixed with
hull of rice (S1M1) gave the highest result on the parameter length of seedling rootwas 9,4 cm.
