In a two-year field experiment changes were observed in the dry weight
level of radish hypocotyl-roots and leaves as well as in soluble sugar and
ascorbic acid of hypocotyl-roots during their growth. Six cultivars were
tested: a) early radish (Rex and Ostergruss Różowa); b) Japanese radish
(Tokinashi and Minowase Summer Cross F1), and c) winter radish
(Monachijska Biała and Murzynka). A considerable variability in the
levels of estimated organic compounds was found between cultivars, harvest
dates, and investigation years. In early radish the contents were lowest,
and in Murzynka - highest. The amounts of dry weight in radish leaves were
greater than in hypocotyl-roots (even double). The trends of changes in
dry weight level during root growth of European cultivars were similar in
leaves and storage organs. For Japanese radish these tendencies were not
comparable. The content of soluble sugar in the hypocotyl-roots of daikon
and winter cultivars increased during the first harvests and then fell considerably.
