Abstrakt: The concept of utilizing light-emitting plants (LEPs) as an alternative to traditional electricity-based lighting has garnered interest. However, challenges persist due to the need for genetic modification or chemical infusion in current LEPs. To address this, researchers have investigated the interaction between plants and luminous bacteria, specifically Vibrio campbellii, which can efficiently be translocated into Aglaonema cochinchinense tissues through the roots to produce LEPs. This study concentrated on examining light intensity and enhancing luminescence by growing plants and spraying them with various media substances. The results indicated that V. campbellii successfully translocated into the plant tissue via the root system and accumulated a high number of bacteria in the stems, approximately 8.46 × 10 4  CFU/g, resulting in a light-emitting intensity increase of 12.13-fold at 48 h, and then decreased after 30 h. Interestingly, luminescence stimulation by spraying the growth medium managed to induce the highest light emission, reaching 14.84-fold at 48 h, though it had some negative effects on the plant. Conversely, spraying plants with CaCl 2 on the leaves prolonged light emission for a longer duration (42 h after spraying) and had a positive effect on plant health, it maintained ion homeostasis and reduced-MDA content. This study highlights the potential of using V. campbellii and CaCl 2 spraying for the future development of practical light-emitting plants.
