Abstract The accuracy of measuring tomato（Lycopersicon esculentum Mill.）leaf area by ImageJ software was confirmed through measuring scanned standard shape. There was no significant difference for area with 100, 200 and 300 DPI. And 200 DPI was better. Two methods of paper-cutting and image processing for measuring tomato leaf area were compared and there was no significant difference. Based on the result, the method of measuring tomato leaf area with scanner and ImageJ software was established.
