| Research Abstract |
In this study, the tubular arrangement of crystal cell which was consisted of calcium oxalate crystal idioblasts (crystal cells) was find in the primary roots of eddo and konjac. Accumulation of Al was observed inside the crystal cells in Al-treated the primary roots of eddo. Additionally, It was suggested that Casparian bands in endodermis obstructed the influx of Al into the inside of stele in the primary roots. Al in the Al-treated roots was detected as nonphytotoxic Al-oxalate complex at a 1:3 ratio by NMR..
