A hydroponic experiment was carried out in order to study the different effects of two forms of nitrogen, i.e.NH:-N and NO~-N on alleviating aluminum (Al) toxicity to rice seedling.Two varieties, Yangdao 6 (indica, sensitive to Al) and Wuyunjing 7 (japonica, tolerant to Al), were used.The results showed that there were no significant differences in water content, root growth characters, root activity, malondialdehyde (MDA) content in roots with and without Al stress after treating with NH+4-N.
