Published literature is investigated regarding the response of plants to various substances to determine the sensitivity of agricultural plants versus other species, the similarity of effects seen at different taxonomic levels, sensitivity of plants growing outdoors versus in a greenhouse, and the sensitivity of different measurement endpoints. We find that agricultural species are not consistently more or less sensitive to the herbicides tested than non-crop species. Genus and family taxonomic groupings may show similar responses among species, but this similarity quickly decreases as the comparison progress between orders and classes. Results from field and greenhouse studies are less in agreement between studies than data from the other topics. Shoot length will be affected at concentrations lower than for other vegetative endpoints for most species tested for inorganic substances, but for organic substances root and shoot mass were more sensitive. Overall, there is no one species or endpoint that is consistently the most sensitive for all species or all chemicals in all soils, and differences in bioavailability among compounds may confound comparison of test results. Therefore, species sensitivity distributions, adjusted for bioavailability when possible, should be considered in order to better evaluate effects to non-target terrestrial plants.
对已发表的文献进行了研究，以了解植物对各种物质的反应，从而确定农业植物与其他物种的敏感性、不同分类水平上观察到的效应的相似性、室外生长的植物与温室中生长的植物的敏感性，以及不同测量终点的敏感性。我们发现，与非作物物种相比，农业物种对所测试的除草剂的敏感性并非始终更高或更低。属和科的分类分组可能在物种间显示出相似的反应，但随着在目和纲之间比较的推进，这种相似性迅速降低。田间和温室研究的结果在不同研究之间的一致性不如其他主题的数据。对于大多数测试无机物质的物种，茎长在低于其他营养终点的浓度下就会受到影响，但对于有机物质，根和茎的质量更敏感。总体而言，不存在一个物种或终点在所有土壤中对所有物种或所有化学物质始终是最敏感的，并且化合物之间生物有效性的差异可能会混淆测试结果的比较。因此，应考虑物种敏感性分布，并在可能的情况下对生物有效性进行调整，以便更好地评估对非目标陆生植物的影响。
