- Abstract
- The common cypress (Cupressus sempervirens) is widespread
throughout the Mediterranean area where it plays an essential role
in the characterization of the landscape, and is widely used for its
aesthetic value and timber production, for protection of soils from
erosion and for windbreaks. In 2009 and 2010 in two young ornamental
plantations in Tuscany and one nursery in Umbria (central
Italy), some specimens of C. sempervirens cv. Bolgheri showed
symptoms of sudden yellowing of the crown starting from the
basal portion, followed by death of the plants. The incidence of
diseased trees was around 10-15% at all sites. A Phytophthora
species was isolated from the rhizosphere and from roots of symptomatic
and dead plants on selective medium PARPH. Morphological
characteristics were registered on 5-day-old cultures grown
on carrot agar. Ribosomal DNA regions (ITS1, 5.8S rDNA and
ITS2) were amplified, sequenced and compared to sequences of
known Phytophthora species from GenBank. Morphological and
molecular results identified this species as Phytophthora cryptogea.
A pathogenicity test was conducted using 3-years-old ramets of
several clones of C. sempervirens grown in pots containing soil inoculated
with sterile millet seeds colonised separately by two isolates
of P. crytpogea. For each P. cryptogea isolate twenty plants
were inoculated and 10 untreated plants were used as controls.
Reduced growth of the roots and crown wilting followed by death
of the plants were observed, thus confirming the pathogenicity of
P. cryptogea on C. sempervirens. This is the first report of P. cryptogea
on C. sempervirens. (literal)
