Pengaruh Berbagai Konsentrasi dan Lama Perendaman Eco Enzyme terhadap Perkecambahan Benih Aren (Arenga pinnata Merr.)

Abstract

Palm seeds require a relatively long time to germinate because they have a thick and hard skin structure. Under natural conditions, palm seeds only germinate after 4-6 months due to the hard seed coat, which prevents water imbibition into the seed. So a dormancy breaking technique using an eco enzyme solution is needed. This research was carried out at the Seed Technology Laboratory, Faculty of Agriculture, Universitas Sumatera Utara at an altitude of ±32 m above sea level, in January-May 2023, using a Randomized Block Design with 2 treatment factors. The first factor is the concentration of the solution with 4 levels, namely concentrations of 25%, 50%, 75% and 100%. The second factor is the soaking time for eco enzyme with 3 levels, namely 24 hours, 48 hours and 72 hours. The parameters observed were seed water uptake, seed growth capacity, germination test, germination rate, vigor index, fresh weight of sprouts, dry weight of sprouts. The research results showed that a 50% concentration of eco enzyme solution could increase the dry weight of sprouts, while increasing the soaking time for eco enzyme could increase seed water uptake, reduce seed growth capacity and increase the percentage of seeds that did not grow. The interaction between concentration and soaking time in the eco enzyme solution had no significant effect on all parameters.
