Abstract

Thermal fluctuations and illumination are both mandatory for the induction of contractile roots in gladiolus. The light stimulus is perceived by the leaves and not by the corms; high light intensities, independent of daylength, are required. High-energy light is presumably necessary not simply for the products of photosynthesis but may be necessary for the translocation of required factors from the leaves to the roots.
