Pengaruh Berbagai Jenis Bahan Perendaman Terhadap Perkecambahan Benih Balsa (Ochroma Pyramidale)

Balsa is originating wood _ from Central America and South America, balsa wood is included wood
secondary after slashing jungle wilderness. Balsa included tree grow fast, deep 5-6 years time can reach
20m high and 40 cm in diameter. Balsa is used For various models of ships, airplanes, gliders, and
building as well as can used become board surf. Balsa seeds included experienced seeds_dormancy
exogenous cause_ No factor default , however factor outside including water, gas and inhibitors
mechanical other . For overcome problem the can done with method scarification mechanics, for
example with soaking water, coconut water and use a solution of KNO3, H2 SO4. Purpose of study This
is For know influence various type material immersion to Power germinate balsa seeds. Study This held
in September 2022 until with December 2022 which took place at the Nursery Permanent BPDASHL
Palu-Poso, Central Sulawesi Province. Study This use method Draft Complete Random (RAL) which
consists of the 4 treatments consisting from P0 = Without immersion ( Control ), P1 = Soaked with water
for 24 hours, P2 = Soaked with coconut water for 24 hours, P3 = Soaked with 0.1 % KNO3 for 45
minutes, and P4 = Soaked in 70 % H2SO4 for 45 minutes. Research results show treatment H 2 SO 4 70 %
showed more results_good on all observation parameters compared with treatment other, where
percentage germination by 90%, power sprouts 90%, and the average rate germination ie 7.16 day
