Do noises influence plant growth
That is why it helps plants when we talk to them
Rape, cabbage and beans, among other things, thrive in the research greenhouse of the University of Hamburg. The plants are obviously doing very well. And that without anyone saying anything. Talking to the vegetables - that sounds pretty weird at first. But the biologist Julia Kehr knows:
A houseplant certainly has more of the small talk than the pansy in the balcony box, where the wind can quickly dissolve the coveted CO2 into air.
Mozart likes wine
There are also scientific studies that are supposed to prove that wine and tomatoes, for example, like to listen to music. According to this, a vintner in Florence has increased his yield and improved the taste of his grapes by showing his plants recordings of Mozart, Mahler and Vivaldi. Other winemakers report similar experiences.
Red tomatoes, on the other hand, are said to be into Simply Red's pop music. Nice stories. According to biologist Julia Kehr, however, they all have a small catch:
Do plants have feelings?
Sound waves that promote growth, carbon dioxide that helps with photosynthesis - it all sounds pretty sober and emotionless at first. And not because plants actually have feelings. In fact, the green stuff has no neurons and no brain that can process stimuli. Nevertheless, plants are by no means simply knitted, emphasizes Julia Kehr:
Professor Frantisek Baluska from the University of Bonn has his doubts. He is convinced that plants, animals and humans are much more similar than classical biology teaches. Therefore, he thinks it is possible that plants could also have feelings:
Plant neurobiology is the name of his research direction, which is very controversial within science. Plant cells are therefore very similar to the nerve cells of animals and humans, the so-called neurons. Because, according to Frantisek Baluska:
Julia Kehr from the University of Hamburg also sees certain similarities between plants, animals and humans. One example is the root networks in the forest. If a tree is attacked by beetles, for example, it sends out messenger substances. They are spread via the underground network and act like a warning signal for neighboring trees. However, it is unclear whether the trees do this on purpose.
Can we eat plants?
Frantisek Baluska from the University of Bonn agrees. Nevertheless, he considers plants to be so complex organisms that eating kohlrabi, garlic and the like could have a certain aftertaste ...
“We have to eat something living. And whether this is as painful with plants as it is with animals or humans, that is always the question. But I guess they somehow have a problem ... "
Julia Kehr, on the other hand, like most scientists, is much more relaxed about it:
“Plants can do great things. But you don't have to try to equate a plant with an animal. You don't have to wait for the fruit to fall ripe from the tree. You can eat lettuce leaves or carrots or other vegetables without a guilty conscience. Plants are not animals and not people! "
