采用功率密度为825 mW/cm2的CO2激光对茄子干种子进行10 s,13 s,15 s的辐照处理,采收期逐次统计小区产量,并通过多项式回归对不同处理小区产量累加值进行了数学模拟,掌握了茄子不同采收期产量变化与激光辐照时间的关系.从t值变化可以看出,在低剂量范围内,随着辐照时间的延长,小区产量累加值增长期也在延长,若期望前期、中期增产显著,则选13 s处理,若期望后期增产应选15 s.

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.
