| Research Abstract |
The continued Al treatment root showed sever rupture formation at root surface and outer cortex region concomitant with higher level of superoxide anion, H2O2 and lignin related with the oxidative stress compared to the recovery root. However, lipid peroxidation was induced in both roots without significant difference. Re-elongation of central cylinder was observed during the recovery treatment. The belt-like region consisting of mainly dead cells was formed on the root surface by Al treatment. The belt 〓like region has a role as barrier inhibiting the entry of toxic Al into the central region. Thus the region seems to have a programmed cell like function.
