This study was carried ou to compare sprouting and sprout growth after the stumps of four Quercus species(Q. mongolica, Q. variabilis, Q. acutissima and Q. dentata) were cut at 20cm from the soil surface in 1996 and 2000 at Mt. Taehwa, Kwangju-Gun, Kyounggi-Do, Korea. The results obtained were as follows: ⑴ Q. mongolica showed most vigorous sprouting, followed by Q. variabilis, Q. dentata, and Q. acutissima. ⑵ The sprouting ability was more vigorous when cut in winter to earl spring than that in summer. ⑶ The initial diameter growth of the sprouts for 2 year after cutting was the highest in Q. acutissima, followed by Q. dentata, Q. mongolica and Q.variabilis, but the growth for 5years after cutting was Q. variabilis > Q. mongolica > Q. dentata > Q. acutissima. ⑷ The height growth of sprouts for 2 years after cutting was the highest in Q. acutissima and followed by Q. mongolica, Q. dentata and Q. variabilis, but the growth for 5 years after cutting was Q. variabilis > Q. mongolica > Q. dentata > Q. acutissima. ⑸ Tending is needed for the stands of Q. variabilis and Q. acutissima to be regenerated successully by sprouting. ⑹ The sprouting ability of Quercus species decreased with incerasing stump diameter, while its diameter growth seemed to increase.
