Abstract
Flowering characteristics and acorn production of Quercus acuta were studied in a Quercus acuta forest at Wando island, Korea. Three sample trees were cut and measured to investigate flowering characteristics during flowering season. Eight $20m{\times}25m$ quadrats were set up and three $1m{\times}1m$ seed traps were established within each quadrat to investigate acorn production. There were no significant differences in number of female and male inflorescence per bearing shoot among crown positions, but these values decreased from the upper part to the lower part of crown. The number of female flowers was 5,025 flowers/tree, and of the total number, 60.3% was in the upper part, 28.4% was in the middle part and 11.3% was in the lower part of crown. The number of male flowers was 7,063 flowers/tree and increased from the lower part to the upper part of crown. Acorn production of total 24 seed traps was 947 acorns/$24m^2$, and of total acorn production, 11.0% was sound, 61.9% was damaged, 25.1% was decayed and 2.0% was empty. Monthly acorn production was 240 acorns/$24m^2$ in August, 632 acorns/$24m^2$ in September, 56 acorns/$24m^2$ in October, 17 acorns/$24m^2$ in November and 2 acorns/$24m^2$ in December. Acorns fallen in October showed higher mean length, diameter and weight than those of other months.
