The present study was carried out at Thong Pha Phum Plantation, Forest Industry Organization in Thong Pha Phum district, Kanchanaburi province. The objective was to study the growth parameters of coppice teak sprouts from stumps of thinning and final cutting which grew in the same area with the additional seedling. One-year-old teaks from coppices and seedlings that additional planting were measured at diameter at 10 cm above ground level (D₁₀), diameter at 30 cm above ground level (D₃₀) and diameter at breast height (DBH). The height growth of teak was also measured. The growth characteristics were compared between coppice sprouts and additional seedling.
Result indicated that the growth ability of coppice sprout of teaks was affected by origin of teak. The coppice sprouts from stump of final cutting were better than from stumps of thinning and additional seedling, while the coppice sprouts from stump of second thinning were better than from stumps of first thinning. The results showed that highly significant difference in all the size parameters among origin of teak trees was found ( p<0.01). The coppice is one of the alternative regeneration systems not only by low cost, but also by enhancing the short rotation and productivity of plantation.
