Density Variation of Different Ages’ Moso Bamboos Within A Bamboo and Among Bamboos
The experiment was conducted to study the basic densities with different ages, different height and different radial po-sitionsto reveal the variation regularities ofP hyllotachys pubescens within a bamboo and among bamboos and investigate the variance test and multiple comparison q test.By regression analysis, the regression equations of the relationship were ob-tained between densities and ages.The radial variation of outer moso bamboo density is maximum, and the inner is mini-mum.The longitudinal variation of density increases gradually from bottom to top.The variation of basic densities at the same age was relatively small except the inner bamboo at one, four and five years, the middle bamboo at one year and the outer bamboo at six years.Variation rule of different age moso bamboo density is that:the basic density of one year is min-imum, that of two years is in rapid growth, that of three years reduces slightly, there is a slight fluctuation with the rising trend, and until the seventh year there is a increasing trend generally.
