The Probability Distribution and Sampling Simulation of the Tracheid Length in Masson Pine

The tracheid length in six tested logs from 20-year-old plantation-grown tree of masson pine(Pinus massoniana Lamb.) were studied. The skew factors and kurtosis factors were evaluated to test the probability distribution towards the tracheid length from the measurements of different sample combinations. Results showed that the length of tracheid in masson pine can be regarded as the random variable and is normally distributed. The property of normal distribution could be revealed just with three woods tested. The computer simulation of tracheid length was made by means of random sampling. There was great agreement between the means of tracheid length from the simulation and the ones from measurement and the relative error was below 0.55%.
