| Abstract | This research studied the effects of different light intensities on the growth, physiological characteristics, and chemical composition of the Daruma variety wasabi (Eutrema japonicum) grown in an environmentally controlled plant factory. Wasabi seedlings were grown under light-emitting diode (LED) lights with four light intensity levels, i.e., 140, 90, 60, and 35 µmol/m2/s. Growth data recorded included plant height (cm), petiole length (cm), leaf number, leaf greenness (SPAD unit) and leaf area (cm2). At 44 weeks after treatment, physiological data such as stomatal conductance, transpiration, and photosynthesis were measured. Yield data included rhizome diameter, rhizome length, and total plant fresh weight. Chemical composition data included non-structural carbohydrates, reducing sugars, total nitrogen content, and glucosinolates. The results found that specify light intensity (35 µmol/m2/s) promoted stem elongation, whereas a light intensity of 140 µmol/m2/s significantly improved the yield and quality of rhizome. This study provides valuable insights into optimizing light conditions for wasabi cultivation in a plant factory. |
