Effects of different concentrations of ZnSO4 at different times on treatments since the treatment on average ± SE activities of mitochondrial respiratory chain complex I (A), II (B), III (C), IV (D) and V (E) in D. huoshanense petals. The superscript symbols * and ** indicate that there is a significant difference between means in p ≤ 0.05 and p ≤ 0.01, respectively. SE, standard error.

Figure 6

Structure diagram of canonical correlation analysis among the activities of mitochondrial respiratory chain complexes (X group), production rates of precursors and ATP (Y group) and emissions of floral volatiles (Z group). (A) shows there is a significantly positive correlation between the X group and the Y group at the statistical 1% level. Similar to (A), (B) also shows a statistical correlation between the X and Z groups. (C) has two canonical correlation coefficients, and they are both statistically significant at the 1% level, indicating that there is a very close positive correlation between the Y and Z group even though their internal canonical loading of each indicator inside the Y and Z group is different.
