Sodium nitroprusside (SNP) could ameliorate the inhibition effect of Al on root growth of rye (Secale cereale L. cv. King) and wheat (Triticum aestivum L. cv. Jinmai47). Respiratory rate, P/O, OPR (oxygenated phosphate rate), R(3) (oxygen consumption rate with ADP and substrate present), R(4) (oxygen consumption rate with substrate) and RCR (respiratory control ratio, R(3)/R(4)) of root tips from rye and wheat decreased, as well as the activities of H(+)-ATPase, H(+)-PPase, Na(+)-K(+)-ATPase, Ca(2+)-ATPase and Mg(2+)-ATPase, but they increased with SNP treatment. It showed that mitochondrial respiratory functions of root tips from rye and wheat were damaged, phosphorylation was un-coupled by Al, but that of rye was less than that of wheat. Rye has high Al-resistance ability than wheat. SNP is one of donor of NO, it is suggested that NO can ameliorate remarkably respiratory dysfunction resulted from Al stress, so that NO can ameliorate the inhibition effect of Al on plant growth.
