Abstract
|
|
|
|
Verticillium tenerum was detected from the samples of potato (Solanum tuberosum L.) and pumpkin (Cucurbita maxima Duch.) in Korea. The samples on which this species was detected were potato tubers collected from Pyungchang and Gimjae, and fruits and seeds of pumpkin from Yeonchon in 2003. The conidiophores of the fungus produced mainly three to five phialides in verticil. The phialides were narrow, flask-shaped, only very slightly swollen at the base, and taper subulately to a narrow neck. They were hyaline, $10{\sim}26{\times}2{\sim}5\;{\mu}m$. The conidia were formed in slimy heads, and were oval to ellipsoidal, pale reddish-brown, $2.5{\sim}7.5{\times}2{\sim}4\;{\mu}m$. The colony on the substrata was unique, showing brick-red color. This is the first report on the distribution of Verticillium tenerum in Korea.
