用筛选的萤光假单胞细菌(fluorescent Pseudomonas spp.)菌株WCS X.13,WCS417和WCS 358处理栽培于水培系统中不同香石竹栽培品种的根部,试验结果表明,在通气的三角烧瓶培养中,香石竹品种Pallas经WCS X.13菌株处理后根长、根重显著高于对照,植株鲜重相对增长率高于对照40％;经WCS417菌株处理根长高于对照,香石竹品种Lena经WCS 417菌株处理植株鲜重相对增长率高于对照32％,在营养膜培养中,在人工接种病原菌Fusarium oxysporum f.sp.dianthi的条件下,中抗品种Pallas经试验菌株处理根部6周以后,植株(根上部)鲜重均高于对照,表现促进植株生长的趋势。
The roots of different Carnation cultivars cultivated in a hydroponic system were treated with screened fluorescent Pseudomonas spp. Strains WCS X.13, WCS417 and WCS 358 and the results showed that in cultured aerated conical flask cultures , The root length and root weight of carnation varieties Pallas after WCS X.13 were significantly higher than that of the control, and the relative growth rate of fresh weight of the plants was 40% higher than that of the control; the root length of WCS417 strain was higher than that of the control, The relative growth rate of fresh weight of WCS 417 strain was 32% higher than that of the control. Under the condition of artificial inoculation of pathogen Fusarium oxysporum f. Sp. Dianthi, the resistant strain Pallas was treated with the test strain for 6 weeks , The fresh weight of the plant (root top) was higher than that of the control, showing the trend of promoting plant growth.
