Studies have revealed that the albiflorin content, a key medicinal component, varies significantly between different populations of P. lactiflora ‘Hang Baishao’, with cultivated varieties showing higher concentrations compared to their wild counterparts (Wang et al., 2014; Jian et al., 2018). This indicates that specific cultivation techniques can be optimized to enhance the medicinal value of P. lactiflora. The growth conditions significantly affect the mineral and active component content in the roots of Hangzhou White Peony. For example, the iron and manganese content show a positive correlation with the total glycoside content, indicating that regulating soil mineral levels can enhance the medicinal quality of P. lactiflora ‘Hang Baishao’ (Li et al., 2019). Moreover, comprehensive microbiome and metabolome analyses have shown that the medicinal cultivar P. lactiflora ‘Hang Baishao’ has a distinct profile of endophytic fungi and metabolites compared to ornamental varieties. The lower diversity and abundance of endophytic fungi in P. lactiflora ‘Hang Baishao’ are associated with higher concentrations of medicinal compounds like flavonoids and phenolic acids (Cheng et al., 2018; Yang et al., 2023). These findings suggest that targeted cultivation practices can significantly improve the medicinal quality of P. lactiflora ‘Hang Baishao’, making it a valuable resource for traditional and modern medicine. 5.3 Economic benefit analysis of technological improvements The economic benefits of technological improvements in the cultivation of P. lactiflora ‘Hang Baishao’ are substantial. The introduction of advanced cultivation techniques, such as optimized chilling treatments and the use of growth regulators, has not only improved the yield and quality of the plant but also its economic viability. For instance, the successful adaptation of P. lactiflora ‘Hang Baishao’ to low-latitude regions has expanded its growing area, thereby increasing its market availability and economic value (Zhang et al., 2019a; 2019b). Furthermore, the development of a multi-criteria decision-making (MCDM) model for evaluating the performance of P. lactiflora‘Hang Baishao’under different climatic conditions has provided a cost-effective and time-saving method for selecting high-quality germplasm. This model has identified P. lactiflora ‘Hang Baishao’as a top-performing cultivar, which can be promoted for large-scale cultivation, thereby enhancing its economic returns (Wang et al., 2022a). The combination of these technological advancements ensures that the cultivation of P. lactiflora‘Hang Baishao’ is not only sustainable but also economically profitable. 6 Case Studies 6.1 Development and optimization of an efficient regeneration system for P. lactiflora‘Hang Baishao’ Paeonia lactiflora is a perennial herbaceous plant with both ornamental and medicinal value. However, its traditional propagation methods are time-consuming and inefficient, making it challenging to meet large-scale production demands. Tissue culture technology offers an effective approach for the rapid propagation and germplasm preservation of peony, making the establishment of an efficient and stable regeneration system a key research focus. Song et al. (2023) developed an efficient regeneration system for Paeonia lactiflora through systematic optimization of culture conditions and plant growth regulators. During the callus induction phase, cotyledons used as explants combined with MS medium supplemented with appropriate concentrations of 6-BA, NAA, 2,4-D, or PIC achieved the highest induction rate of 98.89%, with high-quality callus and significantly reduced browning. In the bud differentiation phase, the combination of TDZ and NAA significantly improved the differentiation rate of adventitious buds, which grew robustly. During the rooting phase, IBA demonstrated superior root-promoting ability, achieving a rooting rate of 38.89% at a concentration of 1.0 mg/L (Figure 3). These improvements significantly enhanced the overall regeneration efficiency of Paeonia lactiflora.
