Gibberellin‐like activity in avocado ( Persea americana ) fruit extracts was measured by the barley endosperm bioassay. Fruit tissues were anlyzed separately during fruit growth. The level of the activity found was very high in the endosperm and in the seed coats, but decreased in the latter during fruit growth. No measurable gibberellin‐like activity was detected in the mesocarp or in the embryo. It is assumed that the seed coats are a site of production of gibberellin‐like substances in the avocado fruit.
