The effect of gibberellins soaking duration on germination frequency and growth of true shallot seed in the nursery

Abstract

Gibberellins are growth regulators that can increase seedling germination of true shallot seed (TSS). This study aims to determine the effect of TSS soaking duration in gibberellins solution on germination and growth of two TSS varieties. The study was conducted from May to June 2020 in Kotarindau Village, Dolo SubDistrict, Sigi Regency. The study used Factorial Randomized Block Design with 2 factors, each repeated 5 times. The first factor is Variety, consisting of Trisula and Lokananta. The second factor is the Seed Soaking Duration (T), consisting of 4 levels which are No Gibberellin Soaking, 2 hours Soaking, 4 hours Soaking, and 6 hours Soaking. To determine the effect of treatment, analysis of variance was carried out, continued with Duncan’s Multiple Range Test (DMRT) at 5% when the results of variance showed significant differences. The results showed that varieties and soaking duration of TSS in gibberellins solution treatments have significant effect on the growth of TSS. The highest number of plant height and number of leaves was obtained in the treatment of Lokananta varieties with 6 hours soaking duration, but not significantly different from the treatment of the Trisula varieties with 2 hours soaking duration in the number of leaves parameters.
