Abstract

Okra plants are generally propagated generatively, but one of the main obstacles to propagating this plant is seed dormancy (hardseedness), which can inhibit germination. Hardseedness is a type of exogenous dormancy that can be overcome through H2SO4 treatment, wich increases the seeds permeability to water and gases. While chemical scarification using H2SO4 has been widely utilized, there has been limited testing on the permeability and mechanical resistance of okra seed coats. This study aimed to obtain the correct technique for breaking dormancy in okra seeds. The study was conducted in April-November 2022 at the Cikarawang experimental field and the IPB Seed Laboratory. The two-factor experiment was structured using a Completely Randomized Design . The first factor: the concentration of the H2SO4 solution consists of four levels, namely control aquadest without H2SO4, 60, 70 and 80%. The second factor: soaking time consists of four levels, namely control, 3, 5, and 8 minutes. The results showed that H2SO4 treatment increased okra seed germination from 61% (control) to 98.1%. The most effective treatment for breaking dormancy based on average sprout dry weight from 0.7 g to 1.93 g is 80% of H2SO4 with a soaking duration of 8 minutes, seedling vigor from 1.5% to 92.5%, and speed of germination from 17.4% to 22.7% is 70% H2SO4 with a soaking duration of 8 minutes.
