Twelve natural Camellia sinensis populations were selected according to district and latitude, and studied to investigate ecology and morphological characteristics of leaves. Camellia sinensis populations were located mainly at the southern slope below 300m in elevation where soil was relatively fertile and soil texture was silt loam. Camellia sinensis was distributed as a population under the tree stratum dominated by Phyllostachys bambusoides, Tarreya nucifera, Robinia pseudo-acacia, Quercus variabilis, Styrax japonica, Celtis choseniana and Acer pseudo-sieboldianum. Density of Camellia sinensis ranged from 6,100 to 37,100 trees/ha. Significant differences in leaf length, leaf width, number of serrations, number of veins, petiole length and leaf area were observed among populations and individuals within populations. Correlation coefficients between leaf length and leaf area and between number of serrations and number of veins showed significantly positive correlation. According to cluster analysis based on the morphological characteristics of the leaves, Camellia sinensis populations were classified into three groups by leaf length and leaf area. The populations which belong to the middle group was classified into two sub-groups by number of serrations and veins.

Twelve Camellia sinensis populations were studied to investigate the biomass distribution related to stand structure. With increasing mean age of the population, mean root collar diameter increased, while mean height, density and root collar area had no correlation with the age. The result of dimension analysis after cutting the sample trees showed that dry weights of stems +branches and root were exponentially increased and dry weights of current leaves and twigs were linearly increased with increasing root collar diameter. However, the dry weight of older leaves was not related to the root collar diameter. The range of total biomass was 1,162∼11,474㎏/㏊ and the range of current leaf biomass was 165∼1,341㎏/㏊. The range of T/R ratio was 1.5∼2.8. The biomass of stems+branches and root were significantly correlated with the root collar area of the population and were not significantly correlated with the mean age, mean root collar diameter and density of the population. The biomass of current leaves and twigs were significantly correlated with the root collar area and density of the population.
