アカマツ林土壌における糸状菌の分布に関する研究(第1報) : 一土壌断面における糸状菌の垂直分布

その他

These studies were performed to get information on the local distribution of soil fungi in pine (Pinus densiflora) forest soil.
As a part of these studies, the vertical distribution of fungi in a soil profile was examined by soil dilution plate method. A_0 horizons were divided into L_1, L_2, F, and H layers ; mineral soil horizons were devided into 0-4 cm., 4-8 cm., 8-12 cm. and 12-16 cm. by depth.
Fungi isolated from A_0 and mineral soil horizons are shown in TABLE 1 and 2. The order of total numbers of fungi on oven dry weight of soil are as follows :
L_1＜L_2＜F＜H＞0-4＞4-8＞8-12＞12-16.
The dominant fungi in each layer are shown in TABLE 3.
An attempt is made to divide the isolated fungi into patterns of vertical distribution which are shown in TABLE 4.
The fungi in each pattern are discussed in its distribution.
