Response characteristics of functional traits of Sophora alopecuroides L. seedlings on the stress of three copper salts

The data were preliminarily collated using Excel 2019 software, and one-way ANOVA (one-way ANOVA) and Duncan's multiple comparisons were carried out using SPSS 26.0 software to compare the extent of differences in each functional trait of bitter pea seedlings under different copper salt stress treatments. The effects of copper salt type, concentration and their interaction on each growth index were examined using two-way ANOVA (two-way ANOVA). Pearson correlation analysis was applied to study the correlation between functional traits and plotted using Origin 2022.
