[求助] 文章的回复关于tukey检验以及曲线拟合的

1. In M&Ms Authors wrote that data were tested by one-way ANOVA (Tukey). However, no ANOVA results were demonstrated further. It is clear from the section “Effect of Zn on plant biomass” that Authors tried to find toxic thresholds for stem or leaf growth using Tukey test for multiple comparisons. Indeed, using nonlinear regression analysis (with lognormal, exponential decay models, etc.) would be more correct and productive in this search. If no toxic threshold was reached in the experiment, at least linear regression could be used to show the trend towards growth inhibition by Zn excess.

2. It is better to present figures 1 and 2 as scatterplots with lines of fit, obtained in regression analysis, since there is not much sense in using mean and standard deviations for three replicates.
审稿人提出这么两个问题，我该怎么回答啊，尤其是第一个using Tukey test for multiple comparisons。还有，我这个实验室一个重金属胁迫植物生长，含有0浓度，浓度依次升高，能做什么曲线啊，线性？感觉不太好。。
