These adaptations are supported by genetic traits that enhance drought resistance and antioxidant potential, making dragon fruit a versatile and economically valuable crop. 7 Implications for Cultivation and Management Practices of Dragon Fruit (Hylocereus spp.) 7.1 Optimization of light and water management for improved growth Effective light and water management are crucial for the optimal growth of dragon fruit (Hylocereus spp.). Dragon fruit plants are known for their ability to survive under less water and poor-quality soils, which makes them suitable for cultivation in arid and semi-arid regions (Salunkhe et al., 2022b). However, intermittent and untimely rains can exacerbate disease conditions such as anthracnose, which affects the overall health and yield of the plants (Salunkhe et al., 2022b). Therefore, implementing controlled irrigation systems that provide consistent moisture levels without waterlogging can help mitigate disease risks and promote healthy growth. Additionally, ensuring adequate light exposure is essential, as dragon fruit plants thrive in well-lit environments (Zhang et al., 2022). Utilizing shade nets or adjusting plant spacing can optimize light penetration and reduce the incidence of diseases caused by excessive moisture. 7.2 Soil and nutrient management for maximizing yield and quality Soil and nutrient management play a pivotal role in maximizing the yield and quality of dragon fruit. The use of organic fertilizers has been identified as a beneficial practice, although its application is currently minimal among producers (Pérez et al., 2023). Enhancing soil fertility through the incorporation of organic matter and balanced fertilization can improve plant health and fruit quality. Regular soil testing and tailored nutrient management plans can ensure that the plants receive the necessary macro and micronutrients. Additionally, addressing soil-borne diseases through proper sanitation and crop rotation practices can further enhance yield and quality. For instance, the management of stem canker caused by Neoscytalidium dimidiatum requires careful monitoring and timely intervention to prevent significant yield losses (Salunkhe et al., 2022a). 7.3 Controlled environment adaptations Adapting controlled environment agriculture (CEA) techniques such as greenhouse and vertical farming can offer significant advantages for dragon fruit cultivation. These methods provide a controlled environment that can mitigate the impact of adverse weather conditions and reduce the incidence of diseases (Neo et al., 2022). Greenhouses can protect plants from excessive rainfall, which has been linked to the spread of anthracnose and other fungal diseases (Salunkhe et al., 2022a; 2022b). Vertical farming, on the other hand, can optimize space utilization and enhance light exposure, leading to improved growth and yield. Implementing these advanced cultivation techniques can also facilitate better pest and disease management, ensuring a consistent and high-quality production of dragon fruit. By integrating these optimized cultivation and management practices, dragon fruit producers can enhance the overall productivity and sustainability of their operations, leading to improved economic outcomes and market potential. 8 Concluding Remarks The morphological and photosynthetic characteristics of dragon fruit (Hylocereus spp.) have been extensively studied, revealing significant genetic variation and biochemical diversity among different species. Morphological traits such as the number of spines, length of areoles, and the color of the peel and pulp are key identifiers for distinguishing between species. Additionally, the biochemical analysis has shown that the peels of dragon fruit have higher phenol and flavonoid content compared to the pulp, indicating a higher antioxidant potential. The presence of high carotenoid and xanthophyll content in certain genotypes suggests their potential for industrial applications in nutraceutical products. Furthermore, the identification of new fungal pathogens affecting dragon fruit, such as Neoscytalidium hylocereum and Fusarium spp., highlights the importance of understanding the plant's disease resistance mechanisms.
