| Abstract: | Phytophthora capsici is a important pathogen to sweet pepper in Shan-
ghai Suburbs. It produces a lot of sporangia, shuttlelike, ellipsoidal, on
carrot agar or in water. It has resistans to malachite green, when the
concentration of malachite green in PDA is 1 ppm it begins to grow. It
can not only utilize nitratenitrogen as the only nitrogen source, but also
starch as the only carbon source. It produces visible brown coloration in
the medium which containscasein hydrolysate-tyrosine. Its maximum growth
temperation is between 34-37℃. |
