Data collection began on January 15, 2025, with observations recorded approximately every three days. All measurements were conducted by the same experimenter to ensure accuracy and consistency. As of January 24, 2025, the results showed that Group A exhibited the most vigorous growth, with leaf lengths of 20 cm, root lengths of 8 cm, and nine flowers in full bloom. Group B displayed slower growth, with leaf lengths of approximately 13 cm, root lengths of 6 cm, and flower buds present but not yet blooming. Group C showed the slowest growth, with leaf lengths ranging from 2 to 5 cm and no flower buds observed (Table 1). Measurements were taken using standard tools such as rulers, and all values were recorded for subsequent statistical analysis. At the end of the experiment, data from all groups were compared and statistically analyzed to reveal the effects of different light conditions and cultivation methods on the growth performance of Narcissus tazetta subsp. chinensis.
