| Abstract: | A cabbage variety with particularly strongly developed leaves and extremely shortened stems (tight heads) was treated during
the first year of its development with growth retardants (CCC and CEPA, Ethephon) at different concentrations. A 4-fold treatment
with CCC, CEPA or a mixture of both proved to be most effective Leaf growth was inhibited by this treatment (head mass decreased)
but stem growth increased. Only in treated plants the bud of the stem apex could break through the leaf sheath and develop
generative stem. The results are discussed as examples of correlative relations between leaf and stem growth.
