Aflatoxin levels and physical properties of corn kernels inoculated with Aspergillus flavus during development and noninoculated kernels were compared in samples with various proportions of the 2 kernel types. The relationship between mean toxin levels and associated standard deviations of 5 samples demonstrated a linear association from the lowest toxin in noninoculated corn through a mixture of 60% inoculated/40% noninoculated. However, at the highest toxin level in the 100% inoculated material, a reduction in sample variation was observed. Examination of individual kernal weights showed that inoculated kernels were distinctly lighter than noninoculated seed. A uniform grinding procedure of the samples yielded heterogeneous particle sizes based on the starting corn. The large particle fraction (greater than 500 micrometers) decreased from 100% noninoculated kernels through the mixtures to the 100% inoculated seed; particles below 150 micrometers were most abundant in the ground samples from inoculated kernels. In addition, the density of particles within a size category varied; lower densities were observed in samples obtained from A. flavus-inoculated kernels.
在含有不同比例两种类型玉米粒的样本中，比较了发育过程中接种黄曲霉的玉米粒和未接种玉米粒的黄曲霉毒素水平及物理特性。5个样本的平均毒素水平与其相关标准偏差之间的关系表明，从未接种玉米中的最低毒素水平到60%接种/40%未接种的混合物，呈现出线性关联。然而，在100%接种材料中的最高毒素水平时，观察到样本变异性降低。对单个玉米粒重量的检查表明，接种的玉米粒明显比未接种的种子轻。对样本进行统一研磨程序后，根据起始玉米产生了大小不一的颗粒。大颗粒部分（大于500微米）从未接种玉米粒的100%，通过混合物逐渐减少到100%接种种子；在接种玉米粒研磨样本中，低于150微米的颗粒最为丰富。此外，同一尺寸类别的颗粒密度也有所不同；从接种黄曲霉的玉米粒中获得的样本密度较低。
