Perkecambahan Benih Kopi Dengan Pemberian Konsentrasi Hormon Giberellin (GA3) dan Jenis Air yang Berbeda

Dede Suhendra, Siska Efendi, Aswaldi Anwar

Abstract

The propagation plants coffee is carried out in generative manner and needs be optimized with treating gibberellin hormone and water temperature to germination stage of coffee seeds.The research conducted at the Seed Technology Laboratory Faculty Agiculture, Andalas University from May to August 2021. Measurement parameters were germination rate (days), normal germination (%), abnormal germination (%) and dead seeds (%). The results showed that germination rate (days), normal germination (%) and abnormal germination (%) showed a significant effect. While the data had no significant effect on the observation of dead seeds (%) in the treatment of gibberellin hormone concentration and treatment of water types, which in the observation of normal sprouts was the highest, namely in the treatment of 400 ppm gibberellin hormone concentration with coconut water (G4J3) of 86.67% and on seed observation. The highest death rate was treatment gibberellin hormone 200 ppm with mineral water temperature 60°C (G1J2) which was 33.33%. Giberelin and mineral water can affect coffee germination.
