摘要:
为探索玉米苗期叶片受到损伤后的响应机理，采用人工模拟的方法研究苗期不同时期叶片损伤对玉米生长发育及产量的影响。结果表明：玉米苗期叶片受到损伤后，受损叶片的脯氨酸含量和丙二醛含量与叶龄和叶片损伤程度呈正相关；在前期对株高、单株叶面积指标影响较大，到成熟期差异不显著。损伤时期、损伤程度与产量间呈负相关。
Abstract:
In order to explore the response of leaves in maize seedlings after injury，the effects of leaf damage on maize growth and yield at different seedling stages were studied by artificial simulation.The results showed that，when the leaves of maize were damaged at seedling stage,the proline and malondialdehyde in damaged leaves were positively correlated with leaf age and damage degree；At the early stage,the index of plant height and leaf area per plant was affected greatly，the effect was less at maturity.There was a negative correlation between the damage period and the degree of damage and the yield.
