N Demand

<div> <p>Nitrogen (N) limitation constrains the magnitude of terrestrial carbon uptake in response to CO<sub>2 </sub>fertilization and climate change. However, the trajectory of N demand, and how it is influenced by continuing changes in CO<sub>2 </sub>and climate, is incompletely understood. We estimate recent changes in global canopy N demand based on a well-tested optimality hypothesis for the control of photosynthetic capacity (<em>V</em><sub>cmax</sub>). The predicted global pattern of optimal leaf-level <em>V</em><sub>cmax </sub>is similar to the pattern derived from remotely sensed chlorophyll retrievals. Over the period from 1982 to 2015, rising CO<sub>2­ </sub>and warming both contributed to decreasing leaf-level N demand. Widespread increases in green vegetation cover over the same period (especially in high latitudes) imply increasing total canopy N demand. The net global trend is, nonetheless, a decrease in total canopy N demand. This work provides a new perspective on the past, present and future of the global terrestrial N cycle.</p> </div>

The Individual

The photosynthetic activity of four Rhododendron simsii cultivars `Dorothy Gish', `Paloma', `White Gish', and `Gloria' were studied at both the individual leaf level using a portable photosynthesis system (closed), or at the whole-plant level using assimilation chambers (semi-open system). Net photosynthetic assimilation curves in response to light in both systems will be established. The experimental points obtained will be adjusted to a photosynthetic model as described in the literature. The model parameters [original efficiency (α) dark respiration (Rd), maximum photosynthetic capacity to saturated light (Pmax)] will be presented. The evolution of these parameters will be presented as a function of the various stages of development. Also a comparison of the four cultivars will be shown.
