Description
Summary:The role and contribution of discriminating indicators of the corolla geometry of five cultural forms of flowered primrose (Primula × polyantha Mill.) in the phenotypic variation of primrose as a potential bioindicator were studied. The proposed set of the corolla’s geometric characteristics (the average rotational pseudosymmetry (η ᵣ), the average bilateral pseudosymmetry (η b), the irregularity index (I ᵣ), and the projective cover index (I ₚc)) allows us to discriminate significantly between the cultural forms of flowered primrose. The major contribution to discrimination is made by the rotary index of pseudosymmetry (η ᵣ).
