FAVARO, M.A et al. Comportamiento de cultivares de naranjo y mandarino respecto a cancrosis en la zona central de Santa Fe. FAVE. Secc. Cienc. agrar. [online]. 2014, vol.13, n.2. ISSN 1666-7719.
In order to analyze the behavior of different orange and mandarin cultivars against citrus bacterial canker in Central Santa Fe, the incidence and severity of the disease were calculated in leaves and fruits of 4 selected branches per tree during spring and summer 2013/14. A complete randomly experimental design with ten replicates per cultivar was used. Data were analyzed using Analysis of variance and means separated by the Tukey's test, through InfoStat Software. Meteorological and phenological data were analyzed in order to explain disease behavior. Between oranges, 'Washington Navel' and 'Lanelate' showed the highest incidence of citrus canker, while 'Midknight', 'Delta Seedless', 'Valencia late' and 'Salustiana' showed intermediate incidence and severity values. The fruits of 'Clemenules' mandarin showed low incidence of canker but their shoots were severely affected. 'Okitsu' mandarin was the most resistant cultivar to citrus canker.
