Pengaruh Konsentrasi dan Lama Perendaman Kolkisin Terhadap Pertumbuhan dan Produksi Kacang Hijau (Vigna Radiata L.) Varietas Vima 1

Abstract

This study aims to determine the effect of concentration and duration of colchicine soaking on the growth and production of mung beans. This research was conducted at Jl. Harmonika, Medan Selayang District from May to December 2024. This research used a 2-factor randomized group design (RAK) method. The first factor is the length of soaking (P): P1 (2 hours), P2 (4 hours), P3 (6 hours). The second factor is the concentration of colchicine (K): K1 (0%), K2 (0.05%), K3 (0.10%). The observed variables were plant height, number of leaves, flowering age, seed weight and 100 seed weight. The results showed that colchicine concentration treatment significantly affected plant height 2-5 weeks after planting, number of leaves 2-3 weeks after planting, flowering age, seed weight per plot, 100 seed weight and pod length. Soaking time treatment only significantly affected the number of leaves at 2 weeks after planting. The interaction between soaking time and concentration treatment had no significant effect on all observation parameters.
