Effect of gravity on the distribution of growth inhibitors in apple tree

B. Borkowska

Abstract


The aim of this work was to find, if there is an asymmetrical distribution of growth inhibitors in apple trees being kept in horizontal position for a short period of time. Two inhibitors were found in the extract of bark and young shoots of investigated trees. These inhibitors are identical with phloridzin and abscisic acid. The content of phloridzin was higher in the samples taken from the upper side than from the lower ones. The results showed lack of asymmetry in ABA distribution.
