摘 要：
Photosynthetic characteristics were probed by sweet maize, waxy maize, high starch maize and common maize. The results revealed that leaf area index (LAI), chlorophyll a content, chlorophyll b content,photosynthetic rate (PR) showed single peak curve at the whole growth stage. The stages of peak were different according to different varieties. NEAUS4 had the lowest peak and while SIDAN 19 had the highest among all stages. Ratio of chlorophyll a to b was low at seedling stage, reached the peak at jointing stage and then declined. SIDAN 19 had the lower level at the last stages.
