Table I. P values for PCs varying by factors analyzed in this study.

Table of Kruskal-Wallis P values for PC1, PC2, and PC3 differing by factors analyzed in this study. Note the extremely significant P values for PCs by all factors. Despite relatively less significant P values compared to other factors, differences in shape with respect to light treatment are detected, especially for PC2.
