etiolation

 [e″te-o-la´shun]
1. blanching or paleness of a plant grown in the dark due to lack of chlorophyll.
2. the process by which the skin becomes pale when deprived of sunlight.

e·ti·o·la·tion

(ē'tē-ō-lā'shŭn),
1. Paleness or pallor resulting from absence of light, as in persons confined because of illness or imprisonment, or in plants bleached by being deprived of light.
2. The process of blanching, bleaching, or making pale by withholding light.

etiolation

the range of symptoms developed by plants when grown in the dark. Examples include: pale yellow or white colour due to lack of chlorophyll, long internodes, small and rudimentary leaves, poor development of lignified tissue.

These results are related to that reported by Berry & Kress (1991) for some heliconia species, since the stems had greater lengths at high shading levels, probably due to etiolation, which is a plant elongation due to the limited light (Deng et al.
Typically, plants were taller in low light environments (likely an etiolation response) and shorter in high light environments.
In pineapple, this type of explant is obtained through etiolation of in vitro plants with the advantage of avoiding injuries in the regeneration region and avoiding callus formation and consequently genetic variation.

This etiolation is even more striking because in certain instances some colors have been preserved, such as the yellow of a lemon in Untitled (Lemon), 2006.
Plants grown under low light, however, are tall as a result of etiolation, which is exaggerated growth of the stem caused by low light levels (Figure 9-3).
Increased etiolation of legume seedlings as N fertilization rates increased under 13-cm and uncut swards was observed.
Etiolation A condition resulting in a plant due to a lack of light.
occurs chiefly among a small number of mostly herbaceous families, and in some species it may develop only after stimulation by etiolation.
The decrease in proportion of long shoots and increased long-shoot length and leaf area in the shade treatment are best explained as reduction in shoot growth compensated by etiolation of stem growth and the production of thin shade leaves.
However, they also reported that this decrease can not be too drastic because it may cause etiolation and prevent chlorophyll activation, which can result in a very severe reduction in growth and plant death.
