- Tree growth is affected by environmental factors, climate condition and tree age. The objective of this study was to evaluate the growth patterns of Chamaecyparis obtusa (C. obtusa) stand in the Gyeongnam province. Data was collected from two cities and one county by using sample quadrats of 20 * 20m. A total of 11 quadrats were used to collect tree height, diameter at the breast height (DBH), annual growth rings and soil data. The data analysis of soil moisture content, pH, organic matter (%), EC (cmol + /kg of soil), and available phosphorous was conducted. Growth ring was analyzed by using computer based software and the ages of the trees were identified. Average growth of height and DBH was computed from the surveyed data and annual growth of each tree was assessed by computer based reading of annual growth rings. The results of the study revealed that tree growth showed a reducing trend along the longevity. It was identified that soil pH, age, variation in annual average temperature, and altitude were the main factors related with growth of C. obtusa trees along the life of the stand.
