THE fluorescence or luminescence of seed of oat varieties when placed under ultraviolet light has currently received considerable attention as a technique for detecting varietal mixtures. A comprehensive review of work prior to 1934 on the fluorescence of seeds under ultraviolet light was presented by Chmelar (4). Centner (7, 8) was among the first to study the fluorescence of cereal crop seeds under ultraviolet light and observed that roots of germinated seeds of yellow and white oats expressed' a different intensity of fluorescence. Hellbo (11) also tested different varieties under ultraviolet light and found varying reactions between white, yellow, g-ay and black seeded oats. In discussing different methods for detecting mixtures in seed lots, Chmelar and Mostovoj (5) pointed out that white and yellow oats could be distinguished by their differential fluorescence. Seed of Boone oats was observed by Jones (12) to fluoresce a dark bronze color under ultraviolet light, and he was unable to alter the fluorescent property of this variety by soaking the seed either in distilled water or sulfuric acid, or by several heat treatments of the seed. He also presented observations on the fluorescent reaction under ultraviolet light of 35 other oat varieties. Ultraviolet light also has been effective in detecting insect egg plugs on grain (13). Newton and Jones (14) used ultraviolet light to detect frost or low temperature injury of potato tubers, and several pathologists have used it in detecting ring rot and leaf roll infection in potatoes. Fluorescence under ultraviolet light was used by Corkill (6) for identifying different species of Lolium. He also studied the inheritance of this character in crosses of two Lolium species and concluded that it was genetically controlled with fluorescence dominant to non-fluorescence. Woodforde (16) studied crosses of perennial and Italian ryegrass and concluded that the fluorescent character was determined by a single dominant factor. A blue fluorescent character in corn has been described by Teas and Anderson (15) and by Anderson (1). They found two different
