Heerema, figure 3, photosynthesis rate and leaf tissue nitrogen concentration

This chart shows how the nitrogen levels in leaf tissue shifts as leaf photosynthetic rates change.

Figure 2. The relationship between photosynthesis rate and leaf tissue nitrogen concentration in ‘Western’ pecan (from Heerema et al., 2014)

Heerema, R.J., D. VanLeeuwen, R. St. Hilaire, V.P. Gutschick, and B. Cook. 2014. Leaf photosynthesis in nitrogen-starved ‘Western’ pecan is lower on fruiting shoots than non-fruiting shoots during kernel fill. Journal of the American Society for Horticultural Science 139(3):267-274.
