Bullseye Flowers go all out for getting noticed by pollinators, like accentuating their centre with a different colour. Now Englisch researchers show in Science Advances that this pattern establishes itself early in hibiscus flower development. The dark yellow stamen full with pollen form a stark contrast with the blue-purple spot that forms the middle ofContinue reading “Bullseye”

Flowers that want to be heard
Flowers that want to be heard Nectar-eating bats find their flowers based on echolocation. This works best with flowers that stick out show American and Colombia researchers in the New Phytologist. Bats pollinated flowers have less showy colours, a wide bell forming corella. They smell musty. And the produce lots of pollen. In addition theyContinue reading “Flowers that want to be heard”
Disrupting hurricanes
Disrupting hurricanes Researchers long thought that plants pollinated by specialised pollinators risk an evolutionary dead end. Now a group of international researchers show in New Pythologist that this does not have to be the case. The Caribbean island Dominica contains an exception on the rule that plants located on islands don’t have specialised pollinators. TwoContinue reading “Disrupting hurricanes”
Pollen navigation
Pollen navigation Multiple fertilizations of an ovule do not contribute to healthy offspring. Plants therefore have taken measures to prevent this. Now researchers from Japan show how a plant manages this. The landing of a pollen grain on a pistil of a flower is only the first hurdle of fertilization. After landing the pollen grainContinue reading “Pollen navigation”
