| Abstract | An investigation of the soil microfungal population in the paddy fields of two locations around Seoul was made at four seasons. By the dilution plate method, a total number of propagules of the microfungi pergram of soil was recorded as 10⁴at the upper layer (0.10cm depth) followed by the middle (10-20cm depth) and the lower layer(20-30 cm depth). The highest number of fungal propagules was 11.0 × 10⁴at the upper layer of the soil collected in autumn. The decreasing tendency of the number of fungal propagules was depend on the increasing depth in paddy fields. Seasonal fluctuation of the fungal population was shown from the highest density of fungal colonies on the plate in autumn season and the lowest one in winter, indicating that the autumn is best season for fungal growth. Generally, the number of the species of Talaromyces in the paddy soils was found to be very high, particularly in autumn, while comparatively low in winter. The highest number of the species of Talaromyces was 6.5 × 10⁴propagules per gram of soil in Yukkog-dong in autumn and the lowest was 0.5 × 10⁴in Shinwon-dong in winter. It is assumed that these fungi grow well also in the warm to the hot seasons. | ||
