and plant dry matter of soybean was studied in 2/3 and
1/5 diluted soils in a greenhouse trial. Soil dilution to
1/5 had no effect on shoot dry matter of soybean but
decreased AM colonisation and root dry weight of
plants. CFU of saprobe fungi, except T. harzianum,
were higher in 1/5 than in 2/3 diluted soils. W. inflatusGliocladium

weight of soybean plant when inoculated together with
Glomus mosseae. The saprobe fungi P. farinosus and T.
pseudokoningii increased the shoot dry weights of
plants grown in 1/5 diluted soil. The shoot dry weight
and AM colonisation in 1/5 diluted soil were also increased
when T. harzianum was inoculated together
with Glomus mosseae. Thus, saprobe fungi increased
AM colonisation of soybean plants by indigenous endophytes.
