PENGARUH INTENSITAS CAHAYA TERHADAP VARIEGASI DAUN TANAMAN SIRIH GADING (Epipremnum aureum)

Abstract

Leaf variegation (color mixing) is an important aesthetic characteristic in ornamental plants, including devil's ivy (Epipremnum aureum). Light intensity is thought to influence the level of variegation, but information on this is still limited. This study aims to examine the effect of various light intensities on the percentage of variegation in devil's ivy leaves. The study used a Completely Randomized Design (CRD) with four light intensity treatments, namely P1 (25%), P2 (50%), P3 (75%), and P4 (100%). Observations were made every 5 days for 50 days, and the data were analyzed using a one-way ANOVA and further tested using Tukey HSD. The results showed that light intensities of 75% and 100% produced higher variegation compared to lower light intensities. From day 30 to day 45, P3 (75%) and P4 (100%) achieved the highest variegation percentages (50% and 57.80%). These results were statistically significant, with differences between treatments being significantly different (F = 15.89 and p < 0.05), with optimal variegation at high light intensities. The conclusion of this study is that light intensity affects leaf variegation in devil's ivy, with optimal variegation for obtaining more attractive plants occurring at light intensities of 75% to 100%.
