Bingenheimer’s resident plant breeder, Ute Kirchgaesser, is on to something. Really, she’s probably on to many things, but to describe them all would take a book and I only have one blog posting.

Ute has what equates to a master’s degree in horticulture, but her German title sounds much better; Meistergartnerin. She got her start in plant breeding with a family run seed company where she learned the basics of traditional plant breeding, and has combined that knowledge with a more esoteric knowledge of an anthroposophical kind. All of these experiences combine to make her something more like and Ubermeistergarternerin if you ask me. But if you ask her, she is just a vegetable breeder.

Ute is working on developing a summer fennel. She is in the process of improving some leek varieties, and also is working to re-invigorate some old kales. She is in charge of the on-site seed production for Bingenheimer’s catalog. And she is also working on a project that even she can’t explain.

In 2002, she began to study what effect musical intervals have on plants. Previous studies have been done that show that plants respond well to classical music, and not so well to death metal. Ute wanted to know if a particular sequence of notes effects plants more than another, and she wanted to know if this effect can be seen in subsequent generations. She set up a research project working with some lettuces, which she surmised would show results quickly due to their rapid growth.

She began to play different intervals of two notes to different batches of lettuce seed before sowing. As a variation, she played to the plants during their initial stages of growth. She noticed some variation, but the changes were not as apparent as she had hoped.

Then she began working with dandelions (Taraxacum officinale). Ute’s anthroposophical background had taught her that different plants respond to different stimuli, well, differently. Dandelions were more open to external influences than most other plants, so the results should be more well defined. And they were. The results also varied from the results she obtained for the lettuce.

She documented very obvious changes, which only became more exaggerated in subsequent generations. These differences had to do with the growth habitat (vigor, arrangement and shape and size of leaves and flowers), strengths and weaknesses of the plants depending on which interval they had been treated with. Some presented their flowers earlier and lower to the ground. Some presented their flowers later, and significantly higher than the tallest leaves. Some plants had very vigorous deep roots, and some had shallower roots. And of course there were some in between. The most obvious changes, though, were found in leaf shape, with some plants presenting a traditional dandelion leaf shape, and some with leaves that were half stem, and some with leaves that were leafy and broad all the way to the root crown. And the variations were markedly along the lines in accordance to the interval that had been played to the seeds and/or young plants in previous generations.

A very interesting and obvious example of this was seen when the plants were all grouped together in a greenhouse in one gallon pots. The plants that had been treated with the fifth interval were almost destroyed by powdery mildew, and these pots were smack dab in the middle of plants treated with third and seventh intervals. In most cases powdery mildew spreads quickly to neighboring plants, especially in a greenhouse environment with little air flow and when the plants are very close together. But in this instance, the plants that were closely packed around the sick ones were not affected by the mildew. Interestingly, the powdery mildew plants produced the most vigorous seeds in the next generation.

Ute says she has a long way to go before her experiments can be drawn to any conclusions as to what the results mean. For now she is content to acknowledge that there are distinct and undeniable differences in plants that have been treated with certain intervals, and that the same interval affects different types of plants differently. At this point Ute is not sure if the variation is along family lines, ie brassicas (cabbages and radishes) vs. umbels (cilantro and parsnips), or if it is along plant type lines, as in root plants (carrots and beets) vs. leaf plants (kale and chard).

She hopes that her work will lay the foundations for work in the future, that will for starters discover if family or plant type has a stronger correlation to response to the intervals. Ute thinks if this type of research is carried out further, we may be able to use intervals in plant breeding to achieve desired traits in plants: for size, shape, flavor, color, or health benefits. At this point, she says, her results have raised far more questions than they have answered. Which must mean that she is on to something.

One Response to “Bingenheimer part two: effects of musical notes on dandelions?”

  1. This find is inspiring. I did a small article on the subject to introduce the idea of music having an effect on plants ( ). Hope more of this kind reaches more people or are being posted so people realize that indeed subtle energies or forces have effect on plants (and animals, etc).
