Summary

Gibberellic acid (GA) was incubated in agar blocks, transported through hypocotyl sections of sunflower plants, and collected in acceptor blocks of plain agar. The amount of GA transported through the sections was tested with dwarf pea plants using a new test method in which the acceptor block was applied directly to the test plant. The GA transport was significantly lower through hypocotyl section from plants which had been treated with triiodobenzoic acid (TIBA) before isolation of the sections. TIBA inhibits the transport of GA.
