The leaf area index is the surface area of leaves
in a canopy per unit surface area of ground. As for the rate of carbon fixation
per unit of ground surface, it would
appear that a single Camissonia leaf [leaf
area index = 1] may fix carbon at a
rate similar to that of an entire productive
corn canopy [leaf area index = 4.3
(D. N. Baker and R. Musgrave [Crop Sci. 4, 127
(1964)1, as cited in Zelitch (8, p. 279).)] and greater than that of a cotton
canopy [leaf area index = 5.7 (D. N. Baker. ibid. 5, 53 (1965).)]. |
