Effects of light on the development of contractile roots of gladiolus were studied.When the corms of gladiolus were planted deeply in soil, the development of thecontractile roots were inhibited and the diameter of the roots were reduced remarkably. The plants whose shesth leaves were removed developed the contractile roots as well as intact plants. When gladiolus were grown under some colour light, the development of the contractile roots were promoted under red light and were inhibited under blue and green light. The plants which had been interrupted with plasticfilm at base of leaves were notformed the contractile roots.  This facts indicated that the development of contractile roots of gladiolus were stimulated by the contractile roots promoters which were produced in the leaf sheath under the light.
