Abstract

This study aimed to compare the growth of chrysanthemum explants from the concentration of Young Coconut Water and Old Coconut Water in vitro. This research was conducted at the Biotechnology Laboratory of Klabat Airmadidi University – Manado, North Sulawesi in February – May 2020. This study used a completely randomized design consisting of Young Coconut Water and Old Coconut Water, each with 3 treatments MS0, 15% and 30% so that 5 treatments were obtained and repeated 10 times. The statistics used are ANOVA and multiple distance difference test. The results of the observational variables used were explant shoot height, 30% Young Coconut Water and 30% Old Coconut Water had an effect on explant shoot height at the age of 2 MSK, 4 MSK and 6 MSK. The explant shoot height data showed that Old Coconut Water was 30% better than Young Coconut Water 30%. The variable number of shoots treated with MSO greatly affected the number of shoots.
