Abstract: Under low nitrogen condition,the photosynthetic productivity and the content of chlorophyll in the three leaves of ear were studied in maize inbred lines.The photosynthetic productivity and the content of chlorophyll in the three leaves of ear all dropped contrast with the control.Using the percentage of dropped content of chlorophyll as the criterion,25 inbred lines could be divided in 4 groups,the maize inbred lines Xu 178 and Liao 5114 had high nitrogen utilization.

Key words: Maize inbred lines, Low nitrogen stress, The content of chlorophyll, Photosynthetic productivity
