摘　　要：采用功率密度为825mw/cm2的CO2激光对茄子干种子进行10s、13s、15s的辐照处理,0s为对照组,然后播种于基质为土的苗盘中,每个处理200粒种子,三次重复,随机排列,出苗10天开始测定不同处理的子叶干重、子叶面积的变化,然后应用多项式回归进行数学模拟,探讨了激光处理对子叶生长的影响及子叶生长规律。Dry s eeds of eggplant were treated with 825mw/cm^2 CO2 laser for 10s、 13s、 15s、 0s a s CK. Then sown in seedling growing plate, 200 seeds each treatment, three repea ts and random permutation. The dry weight and leaf area of cotyledon were measur ed 10 days after emerging. Then mathematical analogue was conducted on the cotyl edon growth of eggplant through multinomial regression to grasp the effects of l aser on cotyledon growth and the law of cotyledon growth.
