而山西平遥产山药D= 0.004 76与山西太谷产山药D= 0.004 27基本没有差异，它们和河北安国产山药D= 0.004 36共同与怀山药有较大的同源性，通过ITS序列分析，这几种不同产地的山药之间碱基仅相差几个，提示它们具有同源性；野生山药与种植山药碱基数目相差较大，说明种植山药在驯化过程中产生了变移，使物种更进化。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
