Description
The relationship between productivity and canopy structure during reproductive growth stage was examined in swards of three temperate grass species, Dactylis glomerata, Festuca pratensis and F. arundinacea. The relationship between extinction coefficient(K) and culm length depended on species, and the relation was positive in short-culmed species but negative in Jong-cul med one. The relationship between productivity and K during this stage was also inconsistent among three species. The relation was negative in D. glomerata, but positive in F. pratensis. And there was no clear relation in F. arundinacea. These relations were discussed in terms of the arrangement of leaves of vegetative and reproductive tillers within a canopy, and a schematic model was made to explain the inconsistency of relations between productivity and canopy structure among three species.
