- •
DM partitioning between leaves and stems in wheat and barley follow a common allometric function.
- •
The more rapid spring growth of barley compared to wheat may be attributed to the higher leaf DM at a given stem DM than wheat.
- •
In wheat, N supply decreased the stem DM proportion of the total above-ground biomass.
- •
During stem elongation, SLA positively correlated with GAI in both crops presumably due to mutual shading.
