Abstract
IT has been shown that day-length regulates both the number of the root nodules and the chlorophyll content of the leaves in the soya bean1,2. There now arise the questions of whether the leaves are receptive organs for the control of nodule formation by day-length, and whether the action of day-length on chlorophyll-content is related to its action on the formation of functional nodules.
