Histochemical staining of roots using hematoxylin showed dark purple color on 1 mm region of Al-treated root apices. The root tips of Al-sensitive rice genotype (IR64 and Krowal) tended to dark purple, contranstly the root tips of Al-tolerant rice genotype (Grogol and Hawara Bunar) did not stained. Based on histochemical staining, Al treatment 12-15 ppm for 72 hours at pH 4.0 can be used to determine level of Al tolerance in riceenaluminumhematoxylinriceUR-Proceedings
