Calcium supply promotes seed germination in Tartary buckwheat (Fagopyrum tataricum) by mediating amino acid and lipid metabolism to drive osmotic regulation and antioxidant responses.

This study elucidates the multiple mechanisms through which calcium regulates the germination of Tartary buckwheat seeds at both physiological and metabolic levels, providing a theoretical basis and practical guidance for the rational application of calcium fertilizers in Tartary buckwheat cultivation.
