Abstract : In a 2-year study with mature trees of the cv. Timour, panicle malformation was associated with a marked decrease in leaf N, K, Mg, Zn, Mn, Cu and Fe contents. The activity of endogenous auxins and gibberellins was considerably higher in malformed than in normal panicles, but was lower in shoots carrying the malformed panicles than in those carrying the normal panicles. It is suggested that the accumulation of hormones in malformed panicles is associated with an ineffective translocation of hormones from the panicles to the shoots.
