Abstract

Four rice cultivars (EEA 304, SUVALE 1, IRGA 408 and CICA 4) were screened in nutrient solution for Al tolerance at 0, 10, 20, 40 and 60 ppm Al concentrations. Al injury was characterized by visual toxicity symptoms, decrease in dry weight of tops and roots, length of roots and plant height. A differential tolerance to Al was found among cultivars. EEA 304 was found to be the most tolerant to Al. The others were found to be susceptible to Al in this order: SUVALE 1 < IRGA 408 < CICA 4.
