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.
