The objective of this work was to determine the effect of low dosage CO 2 laser (825 mW/cm 2) on production of eggplants via radiating their dry seeds (10 s, 13 s and 15 s) and then analyzing plot yield. The result indicates that the longer radiated time was, the later the peak of increasing production appeared. The 13 s treatment was conductive to increment of yield of prophase and metaphase. But 15 s treatment can increase the yield of anaphase. The multi-regression, mathematical analogue was established on different treatment of plot yield accumulative value.
