Claim · model-written summary
The magnitude of the seasonal decrease in Chl and N content did not decrease noticeably as leaves aged.
Verbatim
e1“We applied our model to foliar chlorophyll (Chl) and nitrogen (N) content measured repeatedly on more than 1-year-old leaves of saplings in four evergreen broad-leaved tree species”
e4“The magnitude of the decrease in the Chl and N content in the growth period of current-year leaves (Δγ) did not decrease noticeably as leaves aged”

Other claims from this paper (8)
- Method / resource The model explained large variations in foliar Chl and N content of the four tree species.
- Association Chl and N content decreased from the opening to maturation of new leaves.
- Association Chl and N content increased during the rest period.
- Association For Chl content, the seasonal decrease (Δγ) was positively correlated with the maximum value before leaf opening across species.
- Association For N content, Δγ and the maximum value before leaf opening were not clearly correlated across species.
- Association For N content, Δγ was positively correlated with the maximum value before leaf opening within some species.
- Observation The annual linear trend in Chl and N varied from positive to negative depending on species and leaf age.
- Observation Seasonal fluctuations of Chl and N corresponded to the phenology of current-year leaves.
