| Abstract:
Five cultivars of cabbage were harvested at three maturities and stored at 0–1 °C for up to six months. Carbon dioxide production, core growth, percent dry weight, and changes in glucosinolate content were determined periodically. In general, there was a slight increase in percent dry weight during the initial storage period followed by a slow decline over the next five months. There was a positive relationship between respiration rate and core elongation, both of which were good indicators of the end of the useful storage life of a variety. Twelve different compounds were detected from gas chromatograph analysis of glucosinolate hydrolysis products of the cabbage. 'Green Winter', the only open pollinated cultivar in the trials, showed the greatest variation in glucosinolate content. The individual compounds varied with cultivar, maturity, and storage. | |
