Meanings
-
(uncountable) A physiological disorder in plants, especially leafy vegetables such as lettuce and cabbage, characterized by necrosis or browning of leaf tips or margins, often due to localized calcium deficiency and environmental stress during rapid growth.
The crop was at once harvested for fear that rot might follow the tipburn and vitiate the results of the work.
1902 January 13, Twentieth Annual Report of the Board of Control of the New York Agricultural Experiment Station (Geneve, Ontario County). For the year 1901, page 342:Tipburn of cabbage consists of a breakdown of tissue near the center of the head, developing as the crop approaches maturity.
1961, John Charles Walker, L. V. Edgington, M. V. Nayudu, Tipburn of Cabbage: Nature and Control, Agricultural Experiment Station, University of Wisconsin, page 12:The occurrence of tipburn is corelated with environmental conditions that either decrease transpiration from the leaf surface or promote rapid growth, both of which impair the plants (sic) ability to supply sufficient calcium to growing tissues, which then results in tipburn.
