文摘
- •
Zn uptake affected by soil P patchiness in wheat and cucumber, not in lupin.
- •
All three plants showed a shift in root allocation to P-enriched soil.
- •
Shoot Zn uptake was associated with root length growth in wheat and cucumber.
- •
No effect of preferential cluster root allocation on shoot Zn uptake in lupin.
- •
Application of P fertilizer increased soil DTPA-extractable Zn.
