The aim of this study was to develop a diagrammatic scale to evaluate
black rot (Xanthomonas campestris pv. compestris) severity on kale (Brassica
oleraceae var. acephala) leaves. The diagrammatic scale was developed and
validated with eight levels of severity, ranging from 0.19 to 48.8%. More
than 95% of the leaves collected from the field showed severity levels
ranging from 0.1 to 21%, and 5% of the leaves showed severities higher
than 22%. The validation of the scale was performed by 10 inexperienced
evaluators, and the data were analysed with two methods: linear regression
and Lin?s statistics. Without the scale, most evaluators overestimated
disease severity, whereas the use of the scale resulted in increased
precision, accuracy, repeatability, and reproducibility of the estimates
according to both validation methods. In conclusion, the proposed diagrammatic
scale proved to be useful for assessments of black rot severity
in kale leaves. The scale may be of interest to researches performing studies
on epidemiology or breeding for resistance. |
