STEVEN B JACK; JAMES N LONG Annals of Botany 1991. doi:10.1093/oxfordjournals.aob.a088250
Other claims from this paper (3)
- Observation Lodgepole pine and sunflower had similar canopy structural dynamics under competition but different degrees of plastic response.
- Association Stem volume production efficiency did not decline with mean crown size in sunflower.
- Mechanism The authors attributed the pine efficiency decline to branch biomass accumulation needed for foliage display.
