In May 2012 the influence of bog peat, zeolite, coconut, and vermiculite substrates on Brassica microgreens antioxidant potential was tested in head glass greenhouse of Plant physiology laboratory, Horticulture institute, Lithuanian Agriculture and Forestry Research Centre. The tested crops were kohlrabi 'Delicacy Purple' (Brassica oleracea var gongylodes 'Delicacy Purple '), mustard 'Red Lion' (Brassica juncea 'Red Lion '), chines cabbage 'Rubi' (Brassica rapa var chinensis Rubi'), radish 'Rioja Improved' (Raphanus sativus var. radicula 'Rioja Improved'). The test assessed DPPH* radical binding resolution, determined ascorbic acid, and phenolic levels. Analysis of substrate on accumulation of antioxidant compounds established following sequence: vermiculite > coconut > zeolite > peat. Vermiculite and coconut fiber substrate leads to increased levels of phenolic compounds in Brassica microgreens. Ascorbic acid content material of kohlrabi and radish is not affected. Antioxidant potential of kohlrabi and radish microgreens is substantially increased by the vermiculite and coconut substrate.
