An even stronger relationship was observed between post-anthesis dry matter and post-anthesis N uptake, with highly significant linear correlations in both seasons (0944 ≥ r 2 ≥ 0.918, p < 0.001).

In both cultivars, the maximum stem number increased significantly with increasing density, whereas the productive stem percentage showed a decreasing trend.
In contrast, LS showed an increasing trend in WUE from D2 to D4 and then maintained a relatively high plateau at D4–D5, with only a slight and insignificant decrease (3.7–4.2%) at the highest density. 3.
