| Abstract: | The
optimum temperature for the germination of the spore of Fulvia fulve (Cooke) Ciferri was 25,
and pH value was 4.0-5.0. The spore did not germinate when RH was less than 86% or when it
was insulated from air. The number of sporulation reached the highest on PSA medium. The
pathogen began to sporulate on the fourth day after inoculation on PSA medium and reached its
maximum on the thirteenth day. The thermal death point of the spore was 45 for 5 minutes. The
leaves on the ground or in the upper layer of soil might be the place where the spore
overwintered. |
