Zonal responses of sensitive vs. Tolerant wheat roots during Al exposure and recovery.

Aluminium (Al) irreversibly inhibits root growth in sensitive, but not in some tolerant genotypes. To better understand tolerance mechanisms, seedlings from tolerant (‘Barbela 7/72’ line) and sensitive (‘Anahuac’) Triticum aestivum L. genotypes were exposed to AlCl3 185 μM for: (a) 24 h followed by 48 h without Al (recovery); (b) 72 h of continuous exposure.
