Light is used to enhance the appearance of the fish and supports the survival of living ornamental aquatic plants in aquariums. The light required by the fresh aquatic plants is different among the species. This study examined the effects of light colours, which are white, blue, red, and green on tissue culture-derived Cryptocoryne elliptica grown under submergence conditions. The morphological traits and chlorophyll content of the planets were measured for ten weeks. Results showed that plantlets’ growth under blue light exhibited the longest petioles (4.9 ± 0.5 cm), leaf length (3.0 ± 0.2 cm), leaf width (1.3 ± 0.4 cm), and leaf number per plantlet (p < 0.05) compared to other lights. The highest chlorophyll content (0.72 mg/g fresh wt.) was recorded in the leaves of plantlets under white light. The number of newly produced shoot tips did not significantly differ among the light treatments (p > 0.05). Experimenting with different propagation methods, hormone treatments, or adjustments to light intensity or duration may provide insights into improving the production of new plantlets in future studies.
