Descriptor English: Etiolation
Descriptor Spanish: Etiolado
Descriptor etiolación
Scope note: Cambios físicos en los patrones de crecimiento de una planta causados por una ausencia de luz mantenida. Estos cambios se caracterizan por un aumento en la distancia internodal que producen unos tallos largos débiles, un menor número de hojas y un color amarillo pálido (clorosis). La base fisiológica de la etiolación es la inducción de la fitohormona auxina.

Scope note: Physical changes in the growth patterns of a plant brought on by sustained absence of light. These changes are characterized by lengthened internodes which produce long weak stems, fewer leaves, and pale yellow color (chlorosis). The physiological basis for etiolation is induction of the phytohormone, AUXIN.
