本文在 CO2 激光对石刁桕种子活力影响的研究基础上 ,应用多项式回归对种子活力指标进行了数学模拟。分别得到了发芽种子的胚根长、下胚轴长、发芽率、发芽指数、活力指数、出苗率与 CO2 激光照射时间的数学模型。
Based on the research of the influence of CO2 laser on the seed vigor of Phoebe bryophyta, the seed vigor index was simulated by polynomial regression. The mathematic models of radicle length, hypocotyl length, germination rate, germination index, vigor index, germination rate and CO2 laser irradiation time of germinated seeds were obtained respectively.
