(Table 1). Moreover, the decrease in its root diameter was
significant when it was exposed to both elevated temperature
and CO2 than when it was exposed to the elevated temperature
alone. While both of the root diameter and length of the
radishes ‘Chunha’ and ‘Cheong-un’ grown at the elevated
temperature were lower than those grown at the ambient
temperature. The decrease in the root diameter was greater
than that in the root length.
