Abstract. Every cultivar and species reacted differently to chloromequat and flurprimidol. The applied retardants reduced the plants height of Tagetes patula, but had no influence on height of Impatiens walleriana. Treating with flurprimidol resulted in better flowering of Petunia hybrida ‘Flash Red’ and ‘Bravo Pink’.

Summary
The experiment was carried out in a greenhouse from March to July 2000. Young plants of Tagetes patula, Impatiens walleriana, Petunia hybrida were grown in pots filled by peat substrate. Plants were sprayed with chloromequat and flurprimidol. Both retardants were applied once or twice with a 10 days interval. Species and cultivar reacted differently to both retardants. The applied retardants reduced the plants height of Tagetes patula, but had no influence on height of Impatiens walleriana. Treating with flurprimidol resulted in better flowering of Petunia hybrida ‘Flash Red’ and ‘Bravo Pink’.
