摘　　要：以杂交玉米先玉335为供试材料,用三种不同的红光干扰处理并加上白光为对照,探究不同光质下玉米叶片的光量子利用能力和二氧化碳利用能力。实验结果显示,B+R光下处理的玉米叶片光量子效率最高,G+R光下处理的玉米品种最低,B+R光下处理的玉米品种羧化效率最低,G+R光下处理的玉米品种羧化效率最高。结果表明,经过红光干扰后玉米叶片的光量子利用能力与二氧化碳利用能力有很明显的变化,其中B+R光下处理的玉米叶片和B+R光下处理的玉米叶片差别最明显。The experimental study was carried out by using three different treatments with red light interference and white control.The ability of light quantum utilization and carbon dioxide utilization capacity were investi-gated,The results showed that the maize varieties treated with B+R light were the highest,and the maize va-rieties treated with G+R light were the lowest,but the maize varieties treated with B+R had the lowest car-boxylation efficiency,and the maize was treated with G+R light The highest rate of carboxylation.Therefore,the light quantum utilization ability and carbon dioxide utilization ability of maize leaves after red light interfer-ence were obviously changed.The maize varieties treated with G+R light and the maize varieties treated by G+R were the most obvious.
