Note: r values represent the correlation coefficients between the contents of
soluble sugar or total phenols of the pear leaves and scab resistance in different
scab-resistant cultivars, positive values represent positive correlations, whereas
negative values represent negative correlations; Pīš¤0.05 indicates significant
correlations between the contents of soluble sugar or total phenols in the pear
leaves of different scab-resistant cultivars and scab resistance |
