Popis:	A novel plant growth regulator, pironetin was isolated from the culture broth of Streptomyces sp. NK 10958. Pironetin showed a significant shortening function of the wheat stem length in the pot test. Pironetin showed 13.4% inhibition on the growth of rice stem length at 100 g/10 a when applied 5 days before heading in the semi-field test. The plant growth inhibition with pironetin was not remedied by the additional application of gibberellin. The mode of action of pironetin is different from the inhibition of gibberellin biosynthesis. Pironetin was supposed to inhibit cell division on plant.
