%X The experimental study on the impacts of CO 2 concentration on plant seed germination percentage, germination energy and leaf structure is conducted by using OTC 1 Open Top Chambers. The results show that the impact of CO 2 concentration enrichment on germination percentage is small, but the increase in germination energy is remarkable. The CO 2 concentration enrichment can quicken seed germination. CO 2 concentration enrichment can apparently increase leaf area and dry weight of C 3 crops, but it is not significant for C 4 crops. With CO 2 concentration enrichment, the leaf stoma density becomes small for C 3 crops, but it shows the opposite tendency for C 4 crops (maize). The soil water stress leads to the increase in stoma density. With the CO 2 concentration enrichment, the stoma resistance will be increased, but the transpiration will be decreased.
