Abstract Two genetically modified Tianta 5 inbred maize lines transfected with Lmpsy and Lmlycb were made. And they were treated as the experimental groups. While the normal Tianta 5 inbred maize was used as control group. The photosynthetic rate, the carotenoid concentration, the plant character, the yield, and the biomass of each group were detected. Then the data were analyzed statistically. The results indicated that transfected with the gene of carotenoid metabolism key enzyme, the Tianta 5 inbred maize would be improved in the following respects: the carotenoid concentration, the photosynthetic rate, the accumulated stock of photosynthetic products, the reduction of light pollution.
