Etiolation symptoms and the greening process are usually studied on dark-germinated seedlings and this raises the question--can these results be generalized for plants growing under field conditions? This work examines various aspects of the plastid differentiation under the covering of the achene wall, which often remains attached to the cotyledons of sunflower (Helianthus annuus) seedlings grown under light.
