Bacterial crown gali: a new disease of rose in the Philippines
1993
Bayot, R.G.
A disease resembling bacterial crown gali was observed on stems of roses in one of the gardens in Los Banos, Laguna [Philippines]. Bacterial cells were present in gall tissues and were isolated into pure culture using potato dextrose agar (PDA). White, circular, domed, mucoid colonies developed within 48-72 hours. Cells were rod-shaped, Gram-negative, non-spore forming and aerobic. Bacterial isolates induced the development of typical crown gall symptoms when inoculated onto wounded tomato stems (Cv. VC-11-1). This is the first report of the occurrence of rose crown gali caused by Agrobacterium tumefaciens in the Philippines
