In the conditions of the Republic of Belarus there was there was presented dynamics of biochemical composition of leaves of white cabbage (Brassica oleracea convar. capitata var. alba L.) grafter lines and its effect on yields of plants grown in field and containers. Research results showed that steckling grafter plants of cabbage with later sowing terms under the field conditions accumulated more plastids in leaves. The highest dry matter quantity (12.7%) and its lowest losses were noted at mother plants sown on June 23rd. Growing of mother plants in containers led to formation of lower quantity of pigments, than at the plants which were grown in a field. The highest sum of chlorophylls a and b was marked at plants of the second term of sowing (on June, 23rd) - 1,55 mg/dm2. The content of dry substance in leaves was also lower, than at plants from the field, and change of its content in mother plant leaves during storage was not notable. By the moment of their release from storage the dry matter content was similar to its content in leaves of plants from a field. Research results showed that in case of cultivation in containers the third decade of June was the best for sowing of seeds of late-ripening lines Ег 7 ms and Ег 7 f. In this case there were formed mother plants with the optimum morphometric parameters of growth and the developments which could store well within 4-6 months. During this period they vernalized, and as a result on the second year gave a high yield of seeds in greenhouse conditions (27.8-44.3 gram/plant, with 67.1-84.0% yield of large fraction of seeds with 3-4 mm size).
