Abstract Tuber
formosanum is a truffle species that is endemic to Taiwan. It
is similar to
T. melanosporum and may have
potential for trade in international truffle markets. Naturally the
species is found only in calcareous soils. The results of this study
showed that liming can facilitate the cultivation of
T.
formosanum in naturally acidic soils to which 8333 kg/ha
CaCO3MgCO3 had been added to raise soil pH from 4.5 to 7.0.
Mycorrhizas of
T. formosanum were present on 45% of
the root tips of 4-year-old
Cyclobalanopsis glauca
(Fagaceae) seedlings 2 years after planting. The first ascocarps were
found in the eighth year after planting. Brulés were
discernible around the trees where the ascocarps were found. Soil pH,
total nitrogen, carbon, and sulfur, and available nutrients were highly
variable in man-made
T. formosanum truffieres which
suggests that
T. formosanum could be grown in a
wide range of soils.
