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..

本研究在eddo和魔芋的初生根中发现了由草酸钙晶体成纤维细胞（晶体细胞）组成的管状排列的晶体细胞。在经Al处理的eddo初生根中，在晶胞内观察到Al的积累。此外，有人认为内皮层中的凯氏带阻碍了铝流入初生根中柱的内部。通过 NMR 检测，经铝处理的根部中的铝为无植物毒性的草酸铝复合物，比例为 1:3。
