The content of gibberellin-like substances was reduced to about one seventh in maize and one half in barley and oat plants grown under zinc-deficient conditions compared with control plants grown with sufficient zinc nutrition. The supplement of zinc to zinc-deficient maize plants not only recovered their growth but also increased contents of gibberellin-like substances. The growth cessation in zinc-deficient plants is discussed in relation to the endogenous contents of gibberellin.
