  1. Note: Log10 DNA gene copies quantification data were normalized to the standard curve lines and presented with the means ± standard deviation (n = 20). In the same season, the capital superscript letters in the some row represent the significant difference (P < 0.01); the superscript lowercase letters represent difference (P < 0.05); and there are no differences with same letter (P > 0.05)
