Figure 6.

Histogram displaying the density distribution of leaf area in squarecentimeters, with mean 13.82, median 13.43, standard deviation 5.54, and sample size of 9242. Includes overlaid density curves for different conditions: N, L, G, and W, each with significant a p-value.

Individual leaf area distribution of the 121 Semiarundinaria densiflora culms. “Mean” and “Median” are the mean and median, respectively; “SD” is the standard deviation; n is the total number of leaves in the 121 culms; pN is the probability that the data are consistent with the null hypothesis of a normal distribution; pL is the probability that the data are consistent with the null hypothesis of a log-normal distribution; pG is the probability that the data are consistent with the null hypothesis of the two-parameter Gamma distribution; pW is the probability that the data are consistent with the null hypothesis of the two-parameter Weibull distribution. The colorful curves represent the predicted probability densities for the four distribution functions. “N”, “L”, “G” and “W” for different types of lines represent the norm, log-normal, Gamma and Weibull distributions, respectively.
