Abstract

The interactions of shoots in relation to the transports of IAA and cytokinins were studied in pea plants of cv. Adagumsky having a strong apical dominance (AD) and a dwarf cv. Porta with a weakened AD. In a model system of two-branched seedlings, the shoots of cv. Adagumsky competitively suppressed the growth and IAA export activity (IEA) of each other, and that correlated with the levels of xylem cytokinins (Х-СК), while Х-СК did not participate in this process in cv. Porta. The treatment with GA3 enhanced AD and induced the shoot interaction in cv. Porta, making it similar to cv. Adagumsky.
