Pengaruh Waktu Perendaman Dengan Asam GIBERELAT Terhadap Viabilitas Benih SOLANUM KHASIANUM CLARKE

Effect of soaking time with gibberelic acid on Solanum khasianum CLARKE seed viability.The study was conducted at the Seed Tecnology laboratory of Research Institute for Spice and Medicinal Crops from Juli 1986 – Desember 1986. The objective was to evaluate the effect of soaking time and gibberelic acid concentration on breaking dormancy and Solanum khasianum CLARKE seed viability. S. khasianum seed have dormancy treated with GA3 0, 100, 300, 500, 700, 900, 1100, 1300 and 1500 mg/l concentration on percent germination and seed vigor. Good seed viability produced by combination between soaking time (24 hours) and 1300 mg/l GA3. Percent germination of 87.33%, uniformity of 87% and speed of germination (9,86%/eternal) were produced.
