Heat drastically alters floral color and pigment composition without affecting flower conspicuousness

[Premise]: Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood. Moricandi...

Sumario:[Premise]: Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood. Moricandia arvensis (Brassicaceae) exhibits seasonal floral dimorphism, with lilac spring flowers and white summer flowers. This study examines how heat-driven shifts in floral pigments alter flower color and its perception by pollinators.
