The study found that appropriate light and potassium treatments significantly increase anthocyanin content, enhancing the plant’s metabolic properties. Additionally, the application of mycorrhizal fungi improved D. officinale’s resistance to drought and disease, effectively enhancing growth quality. Case analysis further indicated that pine bark substrate exhibits a high potential for flavonoid accumulation, and different cultivation modes (such as greenhouse and bionic cultivation) also impact the active components of D. officinale in varying ways. This study provides a scientific basis for sustainable cultivation of D. officinale, revealing approaches to optimize cultivation conditions to further enhance its medicinal value in clinical applications. Keywords Dendrobium officinale; Physiological characteristics; Cultivation conditions; Photosynthesis; Mycorrhizal symbiosis 1 Introduction Dendrobium officinale, a perennial epiphytic herb belonging to the Orchidaceae family. As a valuable traditional Chinese medicinal herb, D. officinale is highly regarded for its health-promoting properties, including immune system enhancement, anti-inflammatory effects, and antioxidant potential (Zhang et al., 2014; Liu et al., 2020; Ji et al., 2022). Due to overharvesting and environmental changes, the natural resources of D. officinale are increasingly diminishing, making cultivation a sustainable approach to meet this demand. Optimizing cultivation not only aids in conserving the species but also ensures a steady supply of high-quality raw materials to maintain its medicinal value. Cultivating D. officinale presents specific challenges, as it has stringent and sensitive requirements regarding growth conditions. Unlike many crops, D. officinale requires a unique combination of factors, including suitable humidity, temperature, and light intensity, to ensure successful growth and production of medicinal compounds (Wang et al., 2017; Yuan et al., 2020). Given its high economic value and ecological importance, determining optimal cultivation strategies is essential. The physiological characteristics of D. officinale, such as its photosynthetic pathways, nutrient uptake, and stress responses, play a crucial role in its growth and quality. As an epiphytic orchid, D. officinale has evolved unique adaptations, such as specialized root structures and Crassulacean Acid Metabolism (CAM) photosynthesis, enabling it to survive in nutrient-poor environments (Zhang et al., 2014). Light intensity, temperature, and nutrient availability significantly affect its growth and physiological traits. For instance, appropriate light intensity can enhance seedling growth and physiological characteristics, leading to better quality plants (Li, 2014). Additionally, nutrient management, such as potassium and nitrogen supply, influences the accumulation of active compounds and overall plant health (Jia et al., 2022; Wu et al., 2023). This study systematically analyzes the correlation between the physiological characteristics of D. officinale and its cultivation environment, exploring in depth the effects of various environmental factors on plant growth and quality to identify key physiological traits and cultivation conditions that contribute to the optimal cultivation of D.
