Caption: Figure 1--Phalaenopsis Classic Spotted Pink hybrid development stages (at 120 DASI), in somatic embryos until complete plant: (A) Protocorm showing the formation of morphogenic structures at the explant base, 15 days after SE-induction; (B) Protocorm showing leaf primordia etiolation (#) and morphogenic structure formation at the base (arrow) (20x); (C) Protocorm showing embryos in different stages at the 30th culture day: globular (*), Torpedo (#) and protocormoids ([section]); (D and E) Chlorophyllated protocormoids from somatic embryos; (F) Complete plants derived from somatic embryos generated from protocorms.
Therefore, it is observed that the etiolation of the stem resulted from the competition for quantity and light quality, due to the proximity of plants of different species, being also of the same species, compromising the increment of leaf area, as there is interference in the formation and growth of the leaves (WU et al., 2012).

The disease is caused by one or more Fusarium species and complex of disease symptoms including seedling blight, root rot, crown rot, stunting, and the most classical symptoms of etiolation, hypertrophy effect or excessive elongation of infected plants, foot rot, seedlings rot, grain sterility, grain discoloration with ultimate effect on yield and seed quality have been recorded from different regions of the world (Sun and Snyder, 1981; Ou, 1985; Webster and Gunnell, 1992; Desjardins et al., 2000).
To minimize seedling etiolation, the shelves were arranged in the incubators so the grow lights were 15 cm from the surface of the soil in the trays.
The extra proteins present in V- -seedlings probably were not the same proteins which were present in dark grown seedlings though V- -seedlings also show near etiolation response.
Etiolation in the dark helps the seedling to force its way through the soil before expending all its energy.

Furthermore, the very concept of 'etiolation' which Austin uses in the context of defining the 'parasitic' use of the performative possesses troubling connotations of 'the perverted, the artificial, the unnatural, the abnormal, the decadent, the effete, the diseased', as Andrew Parker and Eve Kosofsky Sedgwick make clear in their introduction to Performativity and Performance.
