Factorial ANOVA results for tested indicators (Z. mays cultivar, hemipteran species, insect abundance and aphid exposure period) and interdependence between these parameters affecting O2•− formation in the maize seedlings.

Df-degrees of freedom; p-values less than 0.05 were considered significant; F-ratio is defined as the variance between samples/the variance within samples.Factorial ANOVA results for tested indicators (Z. mays cultivar, hemipteran species, insect abundance and aphid exposure period) and interdependence between these parameters affecting O2•− formation in the maize seedlings.

自由度（degrees of freedom，Df）；将p值小于0.05作为统计学显著性判定标准；F比值定义为组间方差与组内方差的比值。针对被测指标（玉米（Z. mays）品种、半翅目昆虫物种、昆虫种群丰度及蚜虫暴露时长）的析因方差分析（Factorial ANOVA）结果，以及影响玉米幼苗中超氧阴离子（O2•−）生成的上述参数间的相互作用关系。
