Abstract
Rates of photosynthesis and dark respiration of the ears and flag leaves of
three varieties of wheat grown at 21 DC under a constant light intensity of 3200 f.c.
were measured by infrared gas analysis twice weekly throughout the period of
grain development. Measurements were made on both the intact ears and the
separated grains and ear structures, in air and in a mixture of nitrogen plus 320
p.p.m. C02. Dry weights of the grains, ears, and main stems were also determined.
