Verticillium dahliae Kleb. incites a vascular wilt disease of
mints. Susceptible Mentha piperita L. , resistant M. crispa L.,
and intermediate hybrid 148 were used to study 1) the site of differential
resistance and 2) the role of polygalacturonase (PG) in the
disease syndrome.
Many more V. dahliae propagules were...
The root-lesion nematode, Pratylenchus penetrans (Cobb 1917).
Filipjev and Shuurmans Stekhoven, 1941, is widely distributed throughout
Oregon and other temperate zones of the world. Economically
it is probably the most important plant parasitic nematode in Oregon
because of its abundance, wide host range of economic plants and
interactions with other...
The incitant of Verticillium wilt of peppermint (Verticillium
dahliae Kleb.) causes disease symptoms only in the genera Mentha
(the mints) and Monarda. This fungus is unable to grow saprophytically
through natural soil. V. dahliae survives in soil by colonizing
and forming microsclerotia in susceptible plants, living root tissue
of many...
A greenhouse experiment was conducted in 1991 and in
1992 to determine the effect of soil water pressure on
potato (cv Russet Burbank) plant growth and infection by
Verticillium dahliae. Soil water pressures of -0.01,
-0.03, -0.08, or -0.15 MPa were combined factorially with
two inoculum concentrations, 0 or 10...
A rapid and reliable assay is needed to evaluate hop
resistance to Verticillium wilt caused by Verticillium
dahliae. Assays used in the past are laborious, require
long incubation periods, and usually produce mild symptoms
which are difficult to evaluate and are often not
consistent. A study comparing several methods for...
Roots of greenhouse-grown peppermint (Mentha piperita L.) and spearmint (Mentha spicata L.)
plants and in vitro-grown shoot cultures were inoculated with Verticillium dahliae conidial suspensions to
study symptom development, detection, and elimination of the V. dahliae. There were significant
differences in the symptom expression of control and infected shoot cultures...
