对10个大田牛至野生居群的挥发性成分进行了分析。方差分析表明，生长在不同地点的植物成分之间没有显着差异，这表明成分的差异是遗传来源，而不是来自环境变化。然而，使用新的统计方法（如使用的相关系数，r，作为一个参数值）显示，尽管他们的变化范围缩小，大多数的22个土壤特性（SP）测量相关的挥发性成分的组成。这一分析还表明，主要的挥发性成分进行了修改，在平行响应SP的变化。结果表明，土壤性质的变化影响了O.主要影响因素是土壤微量元素含量和质地。这项研究强调了需要高度敏感的统计工具，以确定自然环境中的环境因素的实际影响，特别是当它们的变化范围很小。
The volatile components of Origanum dayi Post were analyzed in 10 wild populations grown in a limited area. ANOVA tests showed no significant differences among the compositions of plants that grew in different locations, which suggests that differences in composition are of genetic origin and do not spring from environmental variation. However, the use of new statistical methods (such as use of the correlation coefficient, r, as a parametric value) revealed that, despite their reduced range of variation, most of the 22 soil properties (SPs) measured correlated with the composition of the volatile components. This analysis also indicated that the main volatile components were modified in parallel in response to SP variations. It is concluded that variations in soil properties affected the composition of volatile components in O. dayi, and that the main influencing factors were soil microelement contents and texture. This study highlights the need for highly sensitive statistical tools to determine the actual influence of environmental factors in natural environments, especially when their range of variation is small.
