Bicarbonate (HCO₃^-), a byproduct of carbonate rock weathering, may interact with Se, but the synergistic effects of HCO₃^- and Se on Cd transport in selenium hyperaccumulators remain unclear. In this study, <i>C. violifolia</i> was used to examine the impact of different bicarbonate levels on its growth, photosynthesis, intracellular water dynamics, and nutrient transport. As one result, Se⁶⁺ improved the intracellular water-holding capacity (IWHC), the intracellular water/nutrient transfer rate (WTR/NTR), the nutrient translocation capacity (NTC), the nutrient active translocation capacity (NAC), while simultaneously reducing Cd²⁺ translocation. Bicarbonate and Se⁶⁺ together affected Cd²⁺ transport in <i>C. violifolia</i>. The BSC1 treatment (1 mm HCO₃^- addition, 0.46 mm Se⁶⁺ and 0.27 mm Cd²⁺) maximized biomass and photosynthesis, likely due to low HCO₃^- aiding Se⁶⁺ translocation and reducing Cd²⁺ movement. Conversely, BSC3 (15 mm HCO₃^- addition, 0.46 mm Se⁶⁺ and 0.27 mm Cd²⁺) resulted in the smallest biomass and photosynthesis in <i>C. violifolia</i>, as the high HCO₃^- level inhibited the translocation of Se⁶⁺, which decreased the IWHC, WTR(NTR), NTC and NAC. No significant correlation was found between Se-Cd translocation factors, suggesting that HCO₃^- may not directly affect Cd²⁺ transport but could increase root pH, hindering Cd²⁺ movement from roots to shoots.

With increasing market demand outpacing wild resource availability, cultivation has become essential for sustainable production. However, the cultivation of <i>P. sibiricum</i> is challenged by the double dormancy characteristics of seeds, which include embryo and physiological dormancy. This affected the germination of seeds and the establishment of seedlings. This study investigates the role of plant hormones in breaking seed dormancy and regulating germination and emergence in <i>P. sibiricum</i>. We found that cold stratification at 4°C for over 70 d significantly alleviates seed dormancy, associated with changes in endogenous hormone levels. Auxin, gibberellin, abscisic acid, cytokinin, salicylic acid, jasmonic acid, and ethylene were identified as key players in these processes. Exogenous applications of GA3 and 2-coumarate (2-hydroxycinnamic acid) significantly enhanced seed germination, while 6-BA and GA3 promoted corm growth and development. In conclusion, our research provides insights into the hormonal regulation of seed dormancy and germination in <i>P. sibiricum</i>, offering valuable strategies for improving cultivation practices.
