Perkecambahan dan pertumbuhan benih jati (Tectona grandis Linn. f) dalam merespon perbedaan konsentrasi dan perlakuan waktu perendaman benih dalam asam klorida

Teak is a wood-producing plant that in great demand by the community. However, teak seeds are challenging to germinate due dormancy, so special treatment needed before planting. This research aimed determine effect of hydrochloric acid and soaking time on breaking dormancy seed improve its viability. The first factor was concentration with four levels, i.e., 0 M, 0.5 1 1.5 M. second submerging which 12, 18, 24 hours. Parameters observed included percentage germination, maximum growth potential, vigor index, germination rate, simultaneity, height, number leaves, wide leaf. data obtained were analyzed statistically using ANOVA followed DMRT test level 5%. results showed significantly affected width In addition, had significant concluded M 12 hours increased compared control 29.64% 29% 41.66% simultaneity.
