The relationship between chronological age and DNA methylation level of Moso bamboo. Using the integrated data from each primer pair, a quadratic curve was fitted using the SPSS software with an equation of Z = 0.034y2 + 0.828y - 27.762, where P(Q) < 0.01 and R2(Q) = 0.942. Z indicates the chronological age (x axis), y indicates the DNA methylation rate based on the integrated factor (y axis). Data for the nine ages are shown with ○.
