Floral thermogenesis: An adaptive strategy of pollination biology in Magnoliaceae

Floral thermogenesis plays a crucialrole in pollination biology, especially in plant–pollinator interactions. We have recently explored how thermogenesis is related to pollinator activity and odour release in Magnolia sprengeri. By analyz-ing flower temperatures, emission of vol-atiles, and insect visitation, we found that floral blends released during pistil-late and staminate stages were similar and coincided with sap beetle visitation. Thus, odour mimicry of staminate-stage flowers may occur during the pistillate stage and may be an adaptive strategy of Magnolia species to attract pollinators during both stages, ensuring successfu
