Diurnal changes in SLW (specific leaf weight) and TNC (total nonstructural carbohydrates) were observed in alfalfa ( Medicago sativa L.) and corn ( Zea mays L.). In addition to the diurnal pattern of increasing SLW and TNC during the day, immediate changes in SLW and TNC were induced by fluctuations in incident light intensity. Since diurnal change in SLW of fully expanded leaves reflects the photosynthate production‐translocation balance, investigation of the use of change in SLW is suggested as a measure of productivity potential.
