  • 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?

      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

    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.

      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
  • Her first experiment was to simply play a constant tone
  • The plants in the first chamber, with the constant tone, died within fourteen days.
  • 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.

  • 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.

plant hormones

  • (Table 5)
  • Hormones are produced naturally by plants, while plant growth regulators are applied to plants by humans

      This is interesting because it shows you that if you want to manipulate hormones in an experiment you can use plant growth regulators to mimic the action of hormones.

  • There are five groups of plant-growth-regulating compounds: auxin, gibberellin (GA), cytokinin, ethylene, and abscisic acid (ABA).
  • Ethylene is unique in that it is found only in the gaseous form. It
  • induces ripening, causes leaves to droop (epinasty) and drop (abscission), and promotes senescence.

      The effects of ethylene (promotion of both aging/death and ripening) may explain why just one bad apple in a basket may spoil the whole bunch.

    Plant hormones and growth regulators are chemicals that affect flowering; aging; root growth; killing of leaves; prevention or promotion of stem elongation; color enhancement of fruit; prevention of leafing and/or leaf fall; etc.
