Abstract
Under solid cultivating with perlite substrate,six maize inbred lines were subjected to 3 phosphorus deficiency levels: 1) Full P level(CK) with 0.25mol/L KH_2PO_4,2) Low P level(LP) with 10μmol/L KH_2PO_4,3) Extremely low P level(ELP) with 1μmol/L KH_2PO_4.The chlorophyll content,MDA content,POD activity and SOD activity were investigated.Under LP and ELP treatments,chlorophyll content of all inbred lines increased with certain degrees,but activities of POD and SOD showed different trends of changes in different lines.SOD and POD activities in leaves and roots of lines 04099 and 04417 all increased in LP and ELP treatments.Trend of SOD activity changes in 04065 was the same as those of lines 04099 and 04417,but its POD activity change trend was contrary to those of 04099 and 04417.Under two low-phosphorus levels,SOD activities in leaves and roots of 04419 decreased.Its leaf POD activity increased,while root POD activity declined under P deficiency conditions.P deficiency decreased both leaf and root SOD activities of line 04242,while leaf POD activity increased under LP condition and decreased under ELP condition,but root POD activity decreased under both LP and ELP conditions.Trend of SOD activity changes of line 04088 was the same as line 04242.P deficiency enhanced leaf POD activity of line 04088,but the root POD decreased under LP condition and increased under ELP condition.Phosphorus deficiency also changed the membrane lipid peroxidation conditions.Both leaf and root MDA contents showed certain extents of changes under LP and ELP treatments.In summary,lines 04099 and 04417 can be preliminarily regarded as low-phosphorus-tolerant maize inbred lines.
