Notes:
Abstract Bacterial canker disease development was most rapid in all treatments with zero calcium and low (30 ppm) nitrogen. Calcium at 100 ppm or higher in the nutrient solution reduced disease severity in susceptible Moneymaker and resistant Plovdiv 8/12. The resistance of Plovdiv 8/12 was dependent upon adequate calcium. Higher levels of nitrogen (450 ppm) did not result in a significant increase in disease in comparison with the medium levels (240 ppm) of nitrogen. There was no significant interaction between calcium and nitrogen nutrition and disease severity. The (Ca+Mg)/(Na+K) ratio correlated better than calcium alone with reduced disease severity.
