Abstract

Serratia liquefaciens provided better protection of carnations from infection by Fusarium oxysporum f. sp. dianthi, than did Hafnia alvei. The protection occurred when the bacterial isolates were applied to the cuttings before rooting, but not when applied to the root system of rooted cuttings. S. liquefaciens was recovered from carnation stem segments along the stem up to the top after 60 days but after 120 days they were recovered only up to 2.5cm. Zones of inhibition of Fusarium‐conidia sprayed on agar plates previously incubated with stem segments appeared around the bacterial colonies of S. liquifaciens after additional incubation for 24—48h.
