Compared with blue-white fluorescent light at 15 degrees C., blue light and low temperature (10 degrees) resulted in a restriction in the rate of leaf growth due primarily to a sharp fall in specific leaf area with increasing plant size, which was much more pronounced at low temperature. There was scarcely any effect on the leaf weight/total dry weight distribution, but the leaves have a much higher dry matter content than those of plants grown in blue-white light.
