Abstract

THE aerodynamic technique has been
used to determine the vertical transfer
of carbon dioxide between the plant
community and the atmosphere. It has
also been extended to the aerial environment
within the plant canopy to
study the vertical distribution of the
photosynthetic fixation of CO₂. The
method permits the study of carbon
dioxide exchange under field conditions
for agricultural crops. Measurements
of windspeed, plant canopy characteristics
and carbon dioxide concentration
distributions are required. The results
give the relative importance of the
various zones of the plant community
in the net photosynthetic fixation of
CO₂ and the diurnal nature of photosynthesis
under field conditions as well
as immediate response data to environmental
conditions. Such information is
valuable for developing models of ideal
plant morphology, improved planting
patterns for efficient light interception
and photosynthesis, and for input into
simulation programs.
