Pengaruh GA3 Terhadap Viabilitas dan Vigor Benih Bawang Merah

Abstrak

Shallots is one important commodities in Indonesia. Shallots can be propagated using a vegetative seed (tuber) or generative (True Shallot Seed). This study aims to determine the effect of gibberellins (GA3) on viability and vigor of True Shallot Seed. This research wasconducted at the Seed Testing Laboratory, Vegetable Crops Research Institute Lembang from November to December 2015. The study was compiled using a completely randomizeddesign (CRD) with two factors factorial, repeated four times. The first factor is the varietyinclude Tuk-tuk, Trisula and Pancasona. The second factor is concentrationGA3 comprisesthree levels giberrelin GA3 treatment include 0 ppm, 100 ppm and 200 ppm. Parametersobserved include seed moisture content, germination, maximum growth potential, vigorindex, the growth rate of germination, root length and hypocotyl length. The results showedthat concentrationof GA3 solution of 100 ppm and 200 ppm are not able to improve theviability and vigor of botanical onions (True Shallot Seed) were tested.Keywords : Gibberellins ( GA3 ) , True Shallot Seed, viability and vigor
