Research Abstract
Rhizome enlargement occurred in the lotus plants that received the signal of short daylength with one or some of the leaves. Covering with low (red light / far red light) ratio films accelerated rhizome enlargement of the plants even in the long daylength. It was demonstrated that rhizome enlargement started two weeks after short daylength treatments, and it was suggested that gibberellins regulated the rhizome growth (elongation or enlargement). Enlarged rhizomes had dormancy and the dormancy could break by the low temperature treatments.
