Red colouration of tissues occurs as a result of mechanical injuries to petals of Hippeastrum hybr. hort. cv. Winter Carnival or their infection by Phoma narcissi. Microscopic study recorded red pigment formation following mechanical injuries or pathogenic infection of white petals. For comparison, localization of anthocyanins in natural red petals of cv. Red Lion was determined. Red pigment, formed in white petals mechanically injured or infected by Phoma narcissi, is different than anthocyanins
