摘要
This paper studied the content malodialdehyde (MDA) and the leakage rate of electrolyte in leaves of various rice va rieties with different iron toxicity tolerance and of Echinochloa crusgalli under excessive Fe\+\{2+\}(160mg·L -1 ) stress.The results showed that both the MDA content and the leakage rate of electrolyte in leaves of plants were significantly and negatively correlated with the tolerance of test plants to iron toxicity.It was suggested that both MDA content and leakage rate of electrolyte could be used as the index for evaluating the tolerance to iron toxicity.
