Relationships between the chemical composition of radish and some
environmental conditions were investigated. In the analysis of linear
correlation the data from a 4-year field experiment with various dates of
radish sowing and harvest were used.
The content of most of the tested organic and mineral compounds of radish roots was positively
correlated with the total rainfall of the vegetation periods. Higher air
temperature and longer daylength during cultivation had a significant
effect on the synthesis of ascorbic acid. A high negative correlation was obtained between
the temperature in the growing periods of Japanese and
winter cultivars and the dry weight and thiocyanate content in radish
leaves. The content of these compounds was affected positively by the
total rainfall of vegetation periods.
