Two cultivation terms were used: an early and a late one. The early cultivation began in the 19th week, the late one in the 31st week of both 2001 and 2002 years. Four cultivars were tested in the experiment: ‘Apollo F₁’, which was evaluated in each year, ‘Leila F₁’ evaluated in 2001, ‘Lucia F₁’ and ‘Papageno F₁’ evaluated in 2002. The plants planted into pots in the early term (19th week of the year) were insignificantly higher, they created more leaves and had bigger bulbs than the plants cultivated in the late term (31st week). Cyclamens in early term of cultivation flowered 1–2 weeks earlier, but flower development was longer about 2–5 days than in later term.
