etiolation
- noun
- /ˌiːtiˈoʊleɪʃən/
- Specialized
- Plants often display etiolation when grown in low-light conditions, resulting in weak stems and pale leaves.
- etiolation response
Examples
-
Interestingly, when older gametophytes are transferred to dark conditions, they do not show the etiolation response.
Academic text (1998) -
For example, one of the first reported etiolation mutants of Arabidopsis, which lacked the normal stem elongation response in darkness, was also found to have green roots (Chory et al. 1989).
Academic text (2000) -
A mutant stock, det30, is available that shows a much reduced etiolation response.
Academic text (1998) -
Apparently, the absence of chlorophyll in roots is itself a developmental response to darkness that is regulated in part by the same gene as the etiolation response.
Academic text (2000) -
If, in a particular environment, selection favored a mutation at this locus reducing the etiolation response, the linkage between etiolation and root development might limit the response to selection because of the energy costs of unnecessary chlorophyll production in roots.

Academic text (2000) -
The researchers noted that etiolation affected the plant's growth, causing it to lose its vibrant green color due to insufficient light.
-
Many species of plants alter their growth patterns to exhibit etiolation, which makes them look elongate and pale in shade.

Morphology
etiolation = etiolate (semi-transparent) = etiol + ate + ion
Clear derivation from the verb 'etiolate' by adding the nominalizing suffix '-ion'.
Etymology
In botany, etiolation comes from the French étioler, 'to make pale', and it describes what happens when a plant grows in the dark and becomes long, thin and pale. That's why gardeners say a plant is etiolated when it is weak and has little green colour from too little light.
