Influence of temperature on the infectivity of Fusarium oxysporum f. sp. vanillae in Vanilla planifolia and in hybrids V. planifolia x V. pompona

Vanilla planifolia is the main vegetable source of vanillin, a flavoring of wide commercial importance. Fusarium oxysporum f. sp. vanillae, the main V. planifolia pathogen, has devastated whole crops worldwide. Vanilla pompona possesses resistance to common genus pathogens. Extreme climatic variatio...

Fusarium oxysporum f. sp. vanillae, the main V. planifolia pathogen, has devastated whole crops worldwide. Vanilla pompona possesses resistance to common genus pathogens. Extreme climatic variations affect the plant-pathogen interactions. Based on the assumption that temperatures above 28 ºC intensify the infectivity of F. oxysporum in vanilla, was determinate the influence of the increase in temperature on the infectivity of F. oxysporum f. sp. vanillae (strain M21C5) in V. planifolia and two hybrids of V. planifolia x V. pompona. Cuttings roots of hybrids 1 and 2 (V. pompona x V. planifolia) and V. planifolia were inoculated with spore suspensions of F. oxysporum f. sp. vanillae. Disease progression was measured for 60 days at 25, 30 and 35 °C. Five replicates per treatment were used, including a control group. ANOVA post hoc Tukey test (P = 0.05) was used for data analysis. V. planifolia was susceptible at 35 °C and highly susceptible at 25 and 30 °C. Both hybrids were resistant to the pathogen at the evaluated temperatures. Due to the resistance, they showed, the hybrids of V. planifolia x V. pompona are a viable alternative to the pathogen. Vanilla planifolia es la principal fuente vegetal de vainillina, saborizante de amplia importancia comercial. Fusarium oxysporum f. sp. vanillae, principal patógeno de V. planifolia, ha devastado cultivos enteros a nivel mundial. Vanilla pompona poseé resistencia a patógenos comunes del género. Variaciones climáticas extremas repercuten en las interacciones planta-patógeno. A partir del supuesto de que temperaturas superiores a 28 ºC intensifican la infectividad de F. oxysporum en vainilla, se determinó la influencia del incremento de la temperatura en la infectividad de F. oxysporum f. sp. vanillae (cepa M21C5) en V. planifolia y dos híbridos de V. planifolia x V. pompona. Se inocularon raíces de esquejes de V. planifolia y de los híbridos con suspensiones de esporas del hongo. Se midió el avance de la enfermedad durante 60 días a 25, 30 y 35 ºC. Se emplearon cinco réplicas por tratamiento, incluyendo un lote testigo. Se utilizó ANOVA post hoc Tukey (P = 0.05) para analizar los datos. V. planifolia fue suceptible a 35 °C y altamente suceptible a 25 y 30 °C. Ambos híbridos mostraron resistencia al patógeno en las temperaturas evaluadas. Por la resistencia mostrada, los híbridos de V. planifolia x V. pompona son una alternativa viable ante el patógeno.
