By integrating experimental data with molecular studies, the potential roles of key genes such as SOC1 and WRKY33 in the fulfillment of chilling requirements were revealed. Additionally, the study validated the close relationship between the chilling accumulation value (672 CHs) and dormancy release in Hang Baishao buds, while highlighting the pivotal roles of temperature- and photoperiod-related genes in regulating chilling requirements. This provides a clear pathway and reference for further exploration of the molecular mechanisms underlying chilling requirement regulation (Adapted from Zhang et al., 2017) 5 Impact of Cultivation Techniques on Yield and Quality of P. lactiflora‘Hang Baishao’ 5.1 Evaluation of the effectiveness of high-yield cultivation techniques The effectiveness of high-yield cultivation techniques for P. lactiflora‘Hang Baishao’ has been demonstrated through various studies. For instance, the introduction of chilling treatments and the use of growth regulators have shown significant improvements in flowering and growth. Specifically, chilling at 0 °C-4 °C for four weeks combined with irrigation using 300 mg/L humic acid was found to be the optimal combination for hastening flowering and ensuring high-quality blooms (Zhang et al., 2019a). This method not only promotes better bud dormancy release but also enhances the overall growth cycle of the plant, making it more adaptable to low-latitude regions with warmer winters (Zhang et al., 2019a; Wang et al., 2020). Additionally, the integration of long-running quantitative observation (LQO) and multi-criteria decision-making (MCDM) approaches has been effective in evaluating the comprehensive performance of P. lactiflora‘Hang Baishao’ in different climatic conditions. This approach has identified P. lactiflora‘Hang Baishao’ as one of the most adaptable cultivars for southern growing regions, further validating the effectiveness of these high-yield cultivation techniques (Zhang et al., 2019b; Wang et al., 2022a). The use of these advanced evaluation methods ensures that the cultivation techniques are not only effective but also sustainable in the long term.
