Israeli scientists find flowers can hear insects

An Israeli research found that the night primrose flowers, exposed to the sounds of bees and moths wings, distribute the flower pollen and raise the concentration of sugar in their nectar in only three minutes.

Hebrew-language newspaper Haaretz reported on Sunday that the researchers say the discovery may have an impact on understanding the evolution of flowers and insects.

Recent studies have shown how plants respond to light (sense of sight), mechanical stimulation (sense of touch) and chemicals that evaporate in the air (sense of smell).

The latest study by scientists of the Tel Aviv University in the central Israel presents a rapid response of plants to sound.

The study also shows that the reaction of the plants depends on the frequency of the buzzing sounds. When they were exposed to sounds at a higher frequency than those of the pollinators, no increase was found in the sugar concentration in the nectar.

Because nectar production is an energy-demanding activity, plants can accurately invest their resources and focus on pollen activity times. As a result, pollinators will receive more reward per unit of time they invest in a flower.

This discovery may also have further implications, including influencing the evolution of plants and insects.

According to the researchers, the development of flower shape can also be influenced by factors affecting the plants’ hearing ability.

The findings suggest that plants are also affected by other sounds, including human-made ones, that may damage the ability of flower and bees to communicate.
