To examine the effect of root restriction on the nitrate uptake and the nitrate transport system activity, 2-year old “Fenghou” grapevines ( Vitis Vinifera × V. Labrasca) were planted in pots with volume 2 L and 12 L served as root restriction and the control, respectively. The pots were filled with...
