The effectiveness of germination pre-treatment on mung beans, peanuts, and tomatoes

Abstract

Improvement in the germination process will improve the productivity of mung beans (Vigna radiata), peanuts (Arachis hypogaea), and tomatoes (Solanum lycopersicum), the three Indonesian important crops. Seed immersion in the water is one of the germination pre-treatments. The aim of the study was to evaluate the effects of seed immersion in pre-determined water on mung beans, peanuts, and tomatoes germination. The study used a factorial completely randomized design with three factors consisted of water pH (5, 7 and 9), water temperature (27 ºC and 50 ºC), and immersion time (15 and 30 minutes) on 3 replications. Seed germination process was carried out in a rolled paper method. The study showed that different water pH, water temperature, and immersion time gave a significant effect on the germinability, germination speed, seed vigor index, and the percentage of normal growth seeds. Moreover, the seed immersed in the water (pH 7, 50ºC) for 15 minutes showed the best effect on germination quality.
