PCA of seed germination characteristics for different treatment. (A) The biplot of PCA results of germination characters. (B) The contribution of germination characters to PC1 and PC2. Points of varying colors indicated distinct treatments. Three repetitions were denoted by four smaller points of the same color, and mean values were represented by larger circles. The contribution of distinct germination characters to the principal component was represented by the length of the arrows, while the correlation between various germination characters was indicated by the orientation of these arrows. The red dotted line represents the average contribution of the variables
