ABSTRACT

Three methods of application of growth inhibitors were
tested in the cultivation of the French marigold: the soaking of seeds, spraying
the medium a few days after seed sowing, and spraying the seedlings. Use was
made of daminozide contained in the preparation B-Nine 85 SP at concentrations
of 2550 and 4250 mg·dm^-3 (0.3 and 0.5%), and metconazole contained
in the preparation Caramba 60 SL at 300 and 600 mg·dm^-3 (0.05 and
0.1%). The response of the plants depended on the kind, concentration and mode
of application of the retardant. The soaking of seeds of the French marigold
in solutions of the retardants, had an adverse effect on their germination. Soaking
seeds in metconazole, spraying the medium with daminozide at a concentration
of 2550 mg·dm^-3 and with metconazole at 600 mg·dm^-3, as
well as spraying the seedlings with the retardants had an adverse effect on the
flowering of the plants.

Key words: daminozide, metconazole, seedlings.
