| Abstract: | The content of gibberellin-like substances was reduced to aboutone seventh in maize and one half in barley and oat plants grownunder zinc-deficient conditions compared with control plantsgrown with sufficient zinc nutrition. The supplement of zincto zinc-deficient maize plants not only recovered their growthbut also increased contents of gibberellin-like substances.The growth cessation in zinc-deficient plants is discussed inrelation to the endogenous contents of gibberellin.
