These differences are closely related to the plant's health and ornamental characteristics. Moreover, light, as a critical environmental factor for plant growth, directly influences photosynthetic efficiency, morphological formation, and flowering quality (Luo et al., 2024). Therefore, investigating the effects of light conditions and cultivation methods on the growth performance of Narcissus tazetta subsp. chinensis is of significant scientific and practical importance. The growth performance of Narcissus tazetta subsp. chinensis varies under different light conditions (adequate light and insufficient light) and cultivation methods (hydroponics and soil cultivation). Insufficient light can lead to poor growth, while different cultivation methods may affect the plant’s water and nutrient absorption efficiency. The interaction of these factors directly determines the ornamental traits and health of Narcissus tazetta subsp. chinensis (Bian and Pan, 2018; Li et al., 2021). However, research on the combined effects of light and cultivation methods onNarcissus tazetta subsp. chinensis remains limited, and systematic scientific data are lacking. Exploring the comprehensive mechanisms by which these key factors affect Narcissus tazetta subsp. chinensis growth can not only clarify their influence on physiological development but also provide a basis for optimizing cultivation management to enhance its horticultural potential (Li et al., 2013; Zhang et al., 2015). Identifying an economically efficient cultivation model is crucial for improving the growth quality and market value of Narcissus tazetta subsp. chinensis in modern horticultural production. Understanding the mechanisms of light conditions and cultivation methods on Narcissus tazetta subsp. chinensis growth will provide valuable guidance for the efficient cultivation of ornamental plants and open new pathways for diversifying the application of landscape plant resources. This study explores the response mechanisms of Narcissus tazetta subsp. chinensis to hydroponic and soil cultivation methods under different light conditions. It focuses on comparing the effects of adequate and insufficient light on the morphology, physiological traits, and growth quality of Narcissus tazetta subsp. chinensis under varying cultivation methods. It analyzes the interactive effects of light conditions and cultivation methods on the regulatory mechanisms underlying Narcissus tazetta subsp. chinensis growth performance, providing a scientific basis for optimizing cultivation conditions. The findings offer guidance for improving the cultivation techniques of Narcissus tazetta subsp. chinensis, promoting its broader application in modern landscape design and home gardening, and laying a solid foundation for its sustained promotion as a premium ornamental plant. 2 Results and Analysis 2.1 Growth of hydroponically cultivatedNarcissus tazetta subsp. chinensis under adequate light Narcissus tazetta subsp. chinensis in Group A, cultivated hydroponically in an adequately lit office environment, exhibited significant growth advantages. Experimental data show that by January 15, 2025, Group A plants had developed two flower buds, with leaf lengths reaching 15-18 cm. By the morning of January 20, the first flower began to bloom, and flowering continued progressively, with a total of eight flowers blooming by January 25. This demonstrated robust growth and flowering capacity (Figure 1). Overall, Group A plants displayed uniform leaf growth, vibrant green coloration, and a high number of well-developed flower buds. Adequate light played a critical role in this experiment. Sufficient natural light provided a continuous energy source, enhancing photosynthetic efficiency, promoting leaf elongation, and facilitating flower bud differentiation and development (Dou et al., 2014). Additionally, the daytime temperature of approximately 20 °C created optimal conditions for plant metabolism, accelerating the absorption and utilization of nutrients. These results align with existing literature, confirming the crucial role of light and temperature in photosynthesis and plant development (Li et al., 2013). Furthermore, the hydroponic method used for Group A maintained clean water quality, ensuring efficient oxygen and water absorption by the roots and providing a stable supply of nutrients for healthy plant growth.
