The toxicological sensitivity and variability of a range of macrophyte endpoints were statistically tested with data from chronic, non-axenic, macrophyte toxicity tests. Five submersed freshwater macrophytes, four pesticides/biocides and 13 endpoints were included in the statistical analyses. Root endpoints, reflecting root growth, were most sensitive in the toxicity tests, while endpoints relating to biomass, growth and shoot length were less sensitive. The endpoints with the lowest coefficients of variation were not necessarily the endpoints, which were toxicologically most sensitive. Differences in sensitivity were in the range of 10-1000 for different macrophyte-specific endpoints. No macrophyte species was consistently the most sensitive. Criteria to select endpoints in macrophyte toxicity tests should include toxicological sensitivity, variance and ecological relevance. Hence, macrophyte toxicity tests should comprise an array of endpoints, including very sensitive endpoints like those relating to root growth.
利用慢性、非无菌大型植物毒性试验的数据，对一系列大型植物终点指标的毒理学敏感性和变异性进行了统计学检验。统计分析纳入了5种沉水淡水大型植物、4种农药/杀菌剂和13个终点指标。反映根生长的根终点指标在毒性试验中最敏感，而与生物量、生长和茎长相关的终点指标较不敏感。变异系数最低的终点指标不一定是毒理学上最敏感的终点指标。不同大型植物特异性终点指标的敏感性差异在10 - 1000范围内。没有一种大型植物物种始终是最敏感的。在大型植物毒性试验中选择终点指标的标准应包括毒理学敏感性、变异性和生态相关性。因此，大型植物毒性试验应包括一系列终点指标，包括与根生长相关的非常敏感的终点指标。
