Anwendungsbeispiele Englisch
  • Also, the root cap enables geoperception or gravitropism.
  • A clinostat is a device which uses rotation to negate the effects of gravitational pull on plant growth (gravitropism) and development (gravimorphism).
  • A simple example of interaction involves plants: Some plants grow toward the light (phototropism) and some away from gravity (gravitropism).
  • In shoots, growth occurs in the opposite direction, a phenomenon known as negative gravitropism.
  • One such tropism is gravitropism, or the growth or movement of a plant with respect to gravity.

  • Gravitropism is an integral part of plant growth, orienting its position to maximize contact with sunlight, as well as ensuring that the roots are growing in the correct direction.
  • Hydrotropism is difficult to observe in underground roots, since the roots are not readily observable, and root gravitropism is usually more influential than root hydrotropism.
  • Endodermal cells may contain starch granules in the form of amyloplasts. These may serve as food storage, and have been shown to be involved in gravitropism in some plants.
  • The Cholodny–Went model, proposed in 1927, is an early model describing tropism in emerging shoots of monocotyledons, including the tendencies for the stalk to grow towards light (phototropism) and the roots to grow downward (gravitropism).
  • Amyloplasts are thought to play a vital role in gravitropism.

  • Attempting to explain photosynthesis and gravitropism, Wayne has developed and promoted a fringe theory of light and gravity based on a concept of "binary photons".
  • Cytokinin may be an inhibitor of root cap growth that controls early gravitropism in roots.
  • He is known for being a pioneer in the study of the plant hormone auxin, and later for work on desiccation tolerance in seeds and gravitropism.
