一般注記Coppicing is an alternative regeneration method to replanting that reduces reestablishment costs and time. However, whether the growth from coppicing is different from that of the original planted trees is a frequent concern. The growth of teak after coppicing was studied in teak plantations in Uttaradit Province at the Tha Pla Plantation, belonging to Forest Industry Organization (FIO), and the Den Kra Tai and Nam Ang Plantations, belonging to Tha Sao Sawmill Limited Part. The objectives were to compare the growth performance of teak after coppicing and teak from planting, including comparing the growth of teak after coppicing using different management methods.
The results revealed that mean height and diameter at breast height (DBH) of teak from coppicing were significantly higher than teak from planting grown in the same area because of the faster growth of sprouts in the first stage affected the growth of seedling. In contrast, the growth of teak had no significant difference if sprouting occurred in different areas from replanting. The sprouts from a clear cut stump showed better growth than sprouts from thinned stumps. Additionally, the stump diameter was positively correlated with the mean height and DBH of sprouts.
