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.

根茎膨大发生在荷花植物收到短日照的信号与一个或一些叶。覆盖低（红光/远红光）比的电影加速根茎扩大的植物，即使在长日照。结果表明，短日照处理后两周，根茎开始扩大，这表明赤霉素调节根茎的生长（伸长或扩大）。膨大的根状茎具有休眠性，低温处理可以打破休眠。
