在佛罗里达州马纳提县观察到一种补血草属植物的冠腐病。分离到一株无荧光、需氧、革兰氏阴性细菌。人工接种后，出现了与田间症状相似的症状。经生理生化试验鉴定，该菌为侵染柠檬(Limonium spp.)树冠和叶片的假单胞菌。在佛罗里达州的田间种植中已经观察到了几年的植物，估计一次种植的损失高达10%。有些症状类似于炭疽菌冠腐病(4，5)。1982年秋，分离出一种细菌，当接种到普通植物中时，引起的症状与田间自然感染植物上发现的症状相似。根据病原菌的生化和生理特性，确定病原菌为石竹假单胞菌。这被认为是首例细菌性疾病的报告。
A crown rot of statice (Limonium sinuatum) plants was observed in Manatee County, FL. A nonfluorescent, aerobic, gram-negative bacterium was isolated. Upon artificial inoculation, symptoms similar to those in the field were reproduced. On the basis of biochemical and physiological tests, the bacterium was identified as Pseudomonas caryophylliA rot affecting the crown and leaves of statice (Limonium spp.) plants has been observed for several years in field plantings in Florida, with losses estimated as high as 10% in a planting. Some of the symptoms resemble those of Colletotrichum crown rot (4, 5). In autumn 1982, a bacterium was isolated that, when inoculated into statice plants, induced symptoms similar to those found on naturally infected plants in the field. We identified the causal agent as Pseudomonas caryophylli on the basis of biochemical and physiological characteristics of the pathogen. This is believed to be the first report of a bacterial disease of statice.
