There is no adverse effect on %G of both cultivars but GR was negatively affected.
- •
Al toxicity inhibits, generally, early growth and decrease the vigor index.
- •
The “cv White Boston” presented growth stimulation at the highest Al level.
- •
The proline role is difficult to point; however it is an excellent stress indicator.
