Pollinator sensory preferences are also predicted to be a key driver in sexually deceptive orchids.
WebMar 3, 2024 · The importance of visual signals in food-deceptive systems has been proven by experiments. Manipulation of visual signal factors, such as UV reflectance, flower color, and flower and inflorescence shapes, has been shown to increase or decrease the frequency of pollinator visits (Newman et al., 2012; Peter & Johnson, 2008, Jersáková et … WebApr 12, 2024 · This produced poorer resemblance to their flat-topped flower models, resulting in less pollinator visits that negatively impact plant reproduction.
