Relative quantification of DNA from
Tuber melanosporum
mycelia was performed
by conventional and real-time PCR in soil from trees in three truffle orchards of
different ages to determine: (1) whether
burn
appearance is related to the amount
of
T. melanosporum
mycelium in soil, and (2) whether productivity onset and
truffle production are related to (a) the amount of
T. melanosporum
mycelium in
soil, (b) tree height and diameter, (c)
burn
extension and (d) surface rock cover.
The
burn
seems to appear only after a certain amount of mycelium has formed.
Precociously productive trees presented higher quantities of mycelium than
nonproductive trees in the productivity onset study, while highly productive trees
presented less quantities of mycelium than nonproductive trees in the productivity
study. Trees with high but not excessive surface rock cover showed greater truffle
production. Larger trees tended to display a
burn
earlier than smaller trees.
