针对以往生物信息综合评价中生物效应指标权重确定困难、忽视指标个性信息等弱点,应用非参数广义数据包络分析方法给出了一种综合评价电场强度对植物种子影响时效性的分析方法,该方法不仅考虑了种子的个性信息,而且还克服了确定指标权重的困难。应用该方法研究了电场对小麦种子影响的时效性。研究结果表明,在0.5~6.0kV/cm场强范围内,小麦种子幼苗形态指标随电场强度增加呈现振荡性变化,并且随着贮存时间的延长其显著性慢慢消失。
It is a very difficult problem on how to determine the weights between the biological indexes in comprehensive evaluation of biological information. In this paper, we apply the non-parametric generalized data envelopment analysis method to form a comprehensive evaluation method for analyzing the aging property of electric field influence on plant seeds. This method can not only give the individual information of seeds, but also overcome the difficulties of determining index weigh. Then, we analyze the aging property of influence of electric field on wheat seeds by using this method. The results show that the seedling morphological indicators of wheat seeds present oscillatory changes with the increase of electric field intensity when the scope of field strength is 0.45kV/cm-6.0kV/cm, and the significant effects gradually disappear with the extension of storage time.
