A method for producing a stigma-like tissue of a saffron flower comprising (1) culturing a corolla tube of a saffron in the presence of a plant hormone or (2) culturing a female organ and/or a corolla tube of a saffron flower in the presence of a plant hormone and alanine, and a method for producing useful components of a saffron flower, e.g., saffron pigment, from the thus produced stigma-like tissue. The tissue cultures produce larger quantitites of the stigma-like tissue and useful components, compared to that obtained by conventional tissue cultures.
