Onion ( Alliumwakegi Araki) is a popular herb and vegetable commodity that can be used as a flavoring dish or traditional medicine. This study aims to determine the effect of light intensity for callus growth. This research was conducted at Plant Biotechnology Laboratory, Faculty of Agriculture, Tadulako University using Completely Random Design (RAL) with a single factor that is light intensity (A) consisting of 3 levels, i.e., 0-100 lux (A1), 300-800 lux (A2) and 1000-4000 lux (A3). The results showed that the onion cultured on the light intensity 1000-4000 lux accelerated the formation of onion callus varieties of lembahpalu. This callus began to form at 13.17 days after cultured. The light intensity 300-800 lux accelerated callus formation at a high percentage and embryonic callus cells. The percentage of callus formation reached 32.46%, resulting callus color was white up to 4 WAC (Week After Culture). The average color of white callus was found on 4 WAK with the average texture of crumb callus, while at the 6 th and 8 th WAC the color of callus was yellow.
