Abstract
Tissue analysis of 14 cultivars of cabbage (Brassica oleracea L. Capitata group) in both 1974 and 1975 indicated that late maturing cultivars generally were higher in thiocyanate ion (SCN−) content than early maturing cultivars. In both years, there was a significant positive correlation between SCN− content of cultivars and days to maturity. While SCN− content of late-planted (June 18, 1975) unirrigated ‘Badger Market’ and ‘Storage Green’ cabbages were more than twice as high as corresponding late-planted cabbages irrigated 5 times per week, the SCN− content of early-planted (May 6) cabbages of both cultivars was not significantly influenced by irrigation treatment. In contrast, the marketable head fresh weight of both cultivars was lowest in late-planted, unirrigated plots. Head SCN− content was negatively correlated with marketable head fresh weight and with total top weight of both cabbage cultivars.Keywords
