Pemecahan Dormansi Benih Kopi Liberika (Coffea liberica) Menggunakan Ekstrak Eceng Gondok

Abstract

Generative propagation was a form of propagation that coffee growers have so far utilized most frequently. Seed dormancy is a common issue in the production of generative coffee. The length of the germination process undoubtedly affects the quantity of seeds available, hence ZPT soaking is required to get around it. a few the crops that can be utilized a  source of the hormone gibberellin is the water hyacinth. The goal of this study was to find a therapy that would effectively break the dormancy of Liberika coffee seeds by soaking coffee seeds in water hyacinth extract. P0 = Soaking with water for 24 hours (control), P1 = Soaking with water hyacinth root extract for 12 hours, P2 = Soaking with water hyacinth root extract for 24 hours, and P3 = Soaking with water hyacinth root extract for 36 hours. The research was carried out using a design that was completely randomized. The findings indicated that the length of time liberica coffee seeds were soaked in water hyacinth extract have a substantial impact on breaking the dormancy of coffee seeds, as measured by the percentage of time that sprouts appeared and the percentage of time that cotyledons ruptured, as well as germination power and speed. Coffee seeds should be soaked in water hyacinth extract for least 24 hours for the most effective results.
