Fig. 6 Relationship between specific leaf nitrogen at anthesis and a) leaf nitrogen concentration at anthesis (r = 0.82, n = 24, P < 0.001), and b) specific leaf weight at anthesis (r = 0.62, n = 24, P < 0.62) for nine sorghum hybrids grown under terminal water deficit. Total N content was the sum of green leaf N content, dead leaf N content, stem N content, and panicle N content. Both graphs have less than 27 points, since at least one of these components was missing for a number of hybrids, preventing the calculation of SLN for those samples
