Abstract
The relatively high phosphorus efficient maize inbred line(178) and the relatively low phosphorus efficient maize inbred line(065) were used as experimental materials and subjected to 2 phosphorus levels: normal and low.Contents of chlorophyll,soluble sugars,soluble proteins,proline and malondialdehyde(MDA) and activities of superoxide dismutase(SOD),catalase(POD),acid phosphatase(APase) and ribonuclease(RNase) were investigated at the 4-leaf stage of the plants.Under the low P treatment,contents of chlorophyll and soluble proteins decreased while contents of soluble sugars,MDA and proline and activities of membrane protective enzymes and RNase increased in both inbred lines,but APase activity increased in 178 and decreased in 065.These results showed that the changes in chlorophyll,soluble sugars,MDA,SOD,APase and RNase were inconsistent in different genotypes of maize under low P status and,therefore,these indicators may serve as basis for the selection for genotypes of high phosphorus use efficiency.
