Pengujian Daya Berkecambah dengan Metode Pengujian dan Suhu yang Berbeda

Abstract

The proper germination testing method is an absolute condition that must be met in determining the viability of seeds. Seed viability is one of the mandatory tests carried out in determining the quality of seeds to be circulated. This study aims to study germination testing methods related to growing methods and media, temperature and evaluation time of germination from several types of seeds. The study consisted of two sub-topics, namely (1) Germination growth at different test methods and (2) Germination rate at two different temperatures. Experiment 1 used cucumber, caisin, and peanut seeds while the second experiment used corn and onion seeds. Cucumber seeds were tested by 3 methods, namely UKDdp, UDK, and UAK; caisin seeds tested by 1/2 UKDdp and UDK methods; peanut seeds tested by sand and UKDdp methods; corn and onion seeds tested by UKDdp method placed at room temperature and constant. Cucumber, caisin and peanuts are placed on the ecogerminator. Each treatment is repeated 9 times, each replay of 25 grains of seeds. Observations were made on the parameters of germination power and sprouting speed with the observation time referring to the ISTA rules. Cucumber seed data were analyzed with RAL one factor while other plant seeds used t-student. In cucumber seeds, the UKDdp and UAK methods are the best methods in the DB test although they are not significantly different from UDK. In caisin seeds the 1/2UKDdp method is the best method in the germination test and in peanut seeds, the best method in the germination test is UKDdp and sand. Room temperature and constant temperature can be used for corn DB test but growing speed is higher at room temperature. Constant temperature testing is best for onion DB testing with better growing speed than room temperature.
