Using corn as the experiment material,in this experiment 18mW/mm2 CO2 laser radiates corn grain so as to test the effect radiation on the corn seed development.The results show that this treatment produces positive effect on corn grain germination,its further development with in 15d after germination and physiological metabolism.30s treatment has no obvious effect.60s and 90s treatment can have a significant effect on the development of corn seedling.
