Studies on a new bacterial disease and other diseases of anthurium in Trinidad. Breeding anthuriums ( Anthurium andraeanum L.) for resistance to bacterial blight caused by Xanthomonas campestris pv. anthurii in anthurium.Īnaïs, G., Derrasse, A., Prior, P., & Cadic, A. The study provides a quantitative screening method that can be used to breed for resistance to A. In addition to a cultivar dependent mechanism of resistance, the study showed that there is a general mechanism of mature plant resistance. Only two anthurium cultivars showed resistance at both levels. The study provided evidence for two independent mechanisms of resistance, one at the level of entry and infection establishment and the other at the level of severity of infection.
BACTERIAL BLIGHT APPEARS ON ANTHURIUM TRIAL
Of the three most discriminating measures, proportion of infected leaves per plant showed the largest correlations with field resistance measures obtained through a farm survey and a field trial conducted in a sick plot, and was the best measure of resistance. All 9 measures of resistance using the optimized inoculation method were able to differentiate among 14 anthurium cultivars. Injection of 1 mL of 1.5 × 10 9 CFU mL −1 three-quarter way down the intact petiole from the intact leaf lamina of a stage-4 leaf consistently and repeatedly elicited 100% infection in susceptible anthurium cultivars, and was the best inoculation method. Resistance of anthurium cultivars to infection by Acidovorax anthurii, the causal agent of bacterial leaf spot disease was investigated using seven inoculation methods, four inoculum concentrations and two different plant ages towards developing a screening method for identification of disease resistance.
