ABSTRACT

Experiments were carried out in the years 2004–2006 on seven heterosis
cultivars of Pelargonium × hortorum. The aim of the research was
to examine the influence of organic media, i.e. coconut fibre and peat substrate,
on seed germination and growth of seedlings and also to examine the influence
of flurprimidol on growth, conformation and flowering of plants. The seedlings
at the stage of 2–3 leaves were transplanted to 10 cm pots in the same
media – coconut substrate and peat substrate. Additional fertilization
was carried out during plants cultivation. At the stage of 5–6 leaves plants
were sprayed with flurprimidol at a concentration of 15 mg·dm^-3 (Topflor
015 SL), twice, at a two-week interval.

Seeds of Pelargonium × hortorum F1 germinated slightly earlier
and the percentage of germinated seeds was greater in coconut substrate than
in peat substrate. The seedlings were also larger and greener in coconut substrate
compared with peat substrate. Plants cultivated in coconut substrate flowered
earlier than plants grown in peat substrate. The use of flurprimidol induced
earlier flowering of the plants. Cultivar Multibloom Lavender was characterized
by the shortest period from seeds sowing to plant flowering.

Key words: organic media, germination, Pelargonium × hortorum, F1 cultivars, flurprimidol, flowering.
