WebMay 14, 2024 · Inbreeding may in addition disrupt plant-insect interactions. While it is well established that inbreeding can increase a plant’s susceptibility to herbivores by diminishing morphological and chemical defences ( Campbell et al., 2013; Kariyat et al., 2012; Kalske et al., 2014 ), its effects on plant-pollinator interactions are less well understood. WebThis type of self-pollination appears to be an adaptation to the windless, drought conditions that are present when flowering occurs, at a time when insects are scarce. Without pollinators for outcrossing, the necessity of …
