Abstract
The feasibility of testing the resistance of pickling cucumber (Cucumis sativus L.) cultivars to bloater damage was determined using a procedure of artificial carbonation at several concentrations of dissolved CO2 during brine storage of unfermented cucumbers. The use of grade 3-size fruit carbonated to saturation with CO2 during brine storage in 18-liter (5-gal) plastic pails appeared to be a simple, rapid (6 days), inexpensive, and reproducible method to test for cultivar differences in susceptibility to bloater damage. The method involves the use of a prescribed brine composition and sequential introduction of N2 and CO2 into the brined cucumbers. Thirty-five cucumber lines and cultivars were statistically separable using the method. Based on the data collected, it is recommended that 6 replications of 15 grade 3 fruit per cultivar or line be used, although good data can be obtained with as few as 2 replications of 5 fruit.
