Photosynthesis as well as climatic and edaphic factors are responsible for increment in tree biomass. What is their quantitative relation with carbon sequestration?
We have recently published a paper in which we demonstrate that nutrient availability is really important to determine whether a forest will act as a sink or as a source of carbon. Conversely, climate seemed to have little relevance determining carbon sequestration on a global scale.

In case of pines a higher annual rainfall (more than 1200 mm) facilitates nutrient absorption. But certain species show a negative relationship between their growth and rainfall. In such case how the carbon sequestration will get affected?
In case of the Amazonian species Senna reticulata, our results are reinforcing the relevance of sink-source relationship of each species or functional groups, to reponses under a CO2-enriched atmosphere and as a consequence, increasing or not carbon sequestration as biomass and/or reserves.The latest can be used to increase growth in a future stress condition (flooding in our case). http://link.springer.com/article/10.1007%2Fs00468-014-1015-0#page-1
