The DoveSong Foundation -- The effect of Music on Plants (The Plant Experiments) - 0 views

    • emily shy
       
      The plants were actually trying to avoid the music because it stunts their growth! That is incredible!!!
  • with the same song played by strings, the plants bent towards the speaker.

      Strings as opposed to drums and steel percussion. It seems like that is more appealing to humans as well

  • The plants showed no reaction at all to country and western music
  • the plants "liked" the jazz that she played them
  • leaned 30 to 70 degrees away from the speakers
  • The plants in the first chamber, with the constant tone, died within fourteen days.
  • Her first experiment was to simply play a constant tone
  • In the chamber with the soothing music, the plants were growing healthily and their stems were starting to bend towards the radio! In the rock chamber, half the plants had small leaves and had grown gangly, while the others were stunted. After two weeks, the plants in the soothing-music chamber were uniform in size, lush and green, and were leaning between 15 and 20 degrees toward the radio. The plants in the rock chamber had grown extremely tall and were drooping, the blooms had faded and the stems were bending away from the radio.

What effect does music have on plant growth? - 0 views

  • The one that was in the best condition was the plant that was in the room with classical music. The second best plant was the one in the room with no music and the one that didn't do so good was the one in the room with rock music.
  • and Rap was last!

      Interesting. Maybe because of all the drum effects it would cause the plants to be unsettled?

AccessScience | Research Update | Phototropin - 1 views

  • Typically, stems show positive phototropism (movement toward the light), whereas roots exhibit negative phototropic movement (away from the source of light).
  • Arabidopsis contains two phototropins referred to as phot1 and phot2. Mutants of Arabidopsis lacking both phototropins lose their phototropic responsiveness
  • Phototropic response
  • ...10 more annotations...
  • phototropins control the movement of chloroplasts
  • these responses serve to enhance the photosynthetic
  • Phototropins, like photoreceptor pigments associated with mammalian vision, comprise many amino acids (900–1000) that form the main structure of the protein (the apoprotein) to which an accessory chemical cofactor is bound that can absorb light and impart color (the chromophore)
  • a small fraction of the receptor pool is rapidly internalized (within minutes) upon blue light irradiation
  • Phototropins are typically associated with the plasma membrane
  • However, the biological significance
  • As light passes through the stem, it becomes progressively diffracted, thereby generating a gradient of phototropin activation across the organ, with the highest level of activity occurring on the irradiated side
  • In some plant species, including the fern Adiantum capillus-veneris, phototropism and chloroplast movement are induced by red light as well as blue.
  • novel
  • The presence of such a hybrid photoreceptor is proposed to enhance light sensitivity and aid the prevalence of species such as ferns in low light conditions

  • it needs to be limited to three hours a day, rather than played continuously.
  • Effective experiments, however, would need to involve the following factors:

      From no effect to drastic. These results are pretty varied.
  • the high frequency of mechanical waves that run hand in hand with rap and acid rock are damaging to the plant.
  • Plants have no auditory organs. They can't hear any more than you could hear through your skin if you had no ears.

      Just as deaf people can feel vibrations, I would assume that plants can feel the vibration of the music. Either gentle music or jarring music

Essential Plant Nutrients - 1 views

  • Plants require 13 mineral nutrient elements for growth
  • Macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur) are plant nutrients required in the largest amount in plants. Micronutrients (iron, copper, manganese, zinc, boron, molybdenum and chlorine) are required in relatively smaller amounts. Additional mineral nutrient elements which are beneficial to plants but not necessarily essential include sodium, cobalt, vanadium, nickel, selenium, aluminum and silicon
    • bacoco coco
       
      Nutrients (in the soid) are needed either in large amounts (macronutrients), medium amounts (micronutrients), or in trace amounts
  • ...6 more annotations...
  • Five types of deficiency or toxicity symptoms are observed:

      Here are the visible signs if the soil does not have enough of or too much of a nutrient.
    • bacoco coco
       
      Plants can be damaged is there is too much of one nutrient (toxicity) or not enough of a nutrient (deficiency).
  • A nutrient deficiency occurs when the nutrient is not in sufficient quantity to meet the needs of the growing plant. Nutrient toxicity occurs when a plant nutrient is in excess and decreases plant growth or quality

      This table will be very helpful as a visual aid for determining if your experiment is functioning properly. Remember, you can only experiment on one nutrient at a time.

Soil pH, Fertilizers, and Lime - 1 views

  • Lime works best when it is mixed with the soil so it can come in contact with a large volume of the soil water. Since lime is not very soluble, it moves into the soil very slowly when applied to the soil surface
  • A little too much can raise pH to undesirable levels and keep it there, causing serious management problems. Make certain you know how much lime is needed, then apply it over a number of seasons until your soil is back in balance.

    This page elaborates on the Essential Plant Nutrients. This time, talking about the nutrients that are found in the soil itself.

    The project that i would like to do would have something to do with different soils and the different amount of nutrients' they contain effects on the plants.

Plants | Medical Plants | Medicinal Plants | Medicinal Herbs - 0 views

  • Medicinal plants have always been considered a healthy source of life for all people.
  • Therapeutical properties of medical plants are very useful in healing various diseases and the advantage of these medicinal plants is being 100% natural.
  • Nowadays people are being bombarded with thousand of unhealthy products, the level of sensibility infront of diseases is very high and that's why the use of medicinal plants can represent the best solution

Plant Physiology Online: Phototropism: From Photoperception to Auxin-Dependent Changes ... - 0 views

  • Phototropism—the directional curvature of organs in response to lateral differences in light intensity and/or quality—represents one of the most rapid and visually obvious responses of plants to changes in their light environment
  • In nature, stem phototropism likely provides plants with an effective means for maximizing photosynthetic light
  • signal-response components mediating the basal UV-A/blue light-induced phototropic response in seedlings.
  • ...2 more annotations...
  • Phototropism has been the subject of study for more than 120 years
  • Photoreceptor molecules, the phototropins, capable of perceiving directional UV-A/blue light cues have been identified and characterized.

Soil - 1 views

  • Heavy soils are those with a large component of clay in them, because the clay particles bind together to form a heavy, sticky lump which is difficult to dig. Because it is composed of so many fine particles which stick together easily, it is liable to compaction. It holds a lot of water and easily becomes waterlogged, so it is cold and wet in spring, and takes a long time to warm up.
  • Clay soils are usually acidic
  • Heavy clay soils can be improved by adding humus or other organic matter and sharp sand for better drainage
