Only vegetative growth of Cercospora kikuchii occurred on standard laboratory media, on agar media prepared from decoctions of carrot leaves, and on agar media preparad from immature and senescent tissues of alfalfa, corn, cotton, and wheat. Leaf decoction agar from immature soybeans yielded few condiophores, but agar media prepared from senescent soybean plants (SSPA) yielded abundant conidiophores. The fungus sporulated sporulated sparsely on SSPA in continuous darkness, sporulated profusely when exposed to several light regimes. Sporulation was abundant in cultures exposed 8 hr day to illuminationfrom Gro-lux at room temperature. More spores were produced on cultures grown spore transfers then from those grown from mycelial transfers. Transfers spores by tapping the bottom of an inverted petri plate contamini sporulating culture over a plate of fresh SSPA medium produced maximum numbers of spores perplate. |
