摘要: A pot experiment was conducted to investigate differences in antioxidative defence and carbon-nitrogen metabolism between acid-tolerant (YJSM) and acid-sensitive (YHSM) rice cultivars under acid stress. Acid-tolerant and acid-sensitive rice were planted in both acidic soil (pH 4.21) and normal soil (pH 6.13). Forty-eight days after sowing, rice shoots and roots from four treatments were collected, and the other four replicates were harvested at seed maturity. The results revealed that the grain yield of acid-tolerant YJSM was significantly higher than that of acid-sensitive YHSM under acid stress. The activities of antioxidant enzymes (superoxide dismutase and catalase) and contents of non-enzymatic antioxidants (ascorbate and reduced glutathione) of acid-tolerant YJSM were both higher than those of acid-sensitive YHSM under acid stress. Moreover, the enzyme activities (nitrate reductase, glutamine synthetase, glutamate synthase and glutamate dehydrogenase) and product contents (soluble sugar and soluble protein) of carbon-nitrogen metabolism of acid-tolerant YJSM were higher than those of acid-sensitive YHSM under acid stress. The NO3-N and carbon (C) contents in leaves of acid-tolerant YJSM were both significantly higher than those of acid-sensitive YHSM under acid stress. This study suggests that the acid-tolerant rice cultivar has better antioxidative defence and carbon-nitrogen metabolism systems than the acid-sensitive rice cultivar and is more effective in resisting acid stress.
