By suspending cell culture from the callus of P. thugbergii and by fluorescent observation, a new method, which is easy and sensitive to observe cell activity and to test the phytotoxicity of various bacteria, was used. This method can be utilized to study the bacterial toxins. Cultured filtrates of some strains of the nematode-carrying bacteria were bioassayed for their toxicity to suspending cultured cells from P. thugbergii callus. Strong toxic effects were observed by the filtrates of Pseudomonas spp., P. fluorescence, and Sphingomonas spp., these bacteria species are coincide with those in the early stage of pine wilt disease.
