limiting, there is no effect of photosynthesis on growth. Allocation to leaf
area increases as the intrinsic photosynthetic capacity is reduced, resulting in
a carbon gain compensation similar to that which occurs under reduced
light or CO2, Under conditions where photosynthetic capacity is high, but
N availability is low, starch accumulates, and conversely when there is high
N availability and low photosynthetic capacity, N accumulates. The best
predictor of allocation appears to be the ratio of photosynthesis to N uptake
(shoot/root activity), rather than absolute rates of shoot or root activity or
concentrations of carbon or N storage forms.
