Abstract
Comparative studies on four cultivars of potted freesia: Pinokkio, Popey, Smarty and Suzy were conducted in the years 1997-98. From January to June freesias were grown in a greenhouse and after the harvest the corms were stored from 5 to 11 months at the temperatures: 0.5-3º C, 14-18º C and 28-30º C. Five corms were planted in a pot into neutralised sphagnum peat.
The following fertilization methods were applied:
1. slow-release fertilizer Osmocote Plus 5-6 before planting;
2. popular, traditional fertilizer, Azofoska before planting;
3. liquid fertilizer Multivit Plus top-dressing;
4. no fertilizer.
Corm preparation before planting was found to have the greatest effect on the growth and development of the plants.
The best results were obtained when the corms were stored 12- 14 weeks before planting at the temperature of 28-30º C. The plants fertilised with Osmocote Plus at the dose of 5g /dm3 had the most abundant flowering Popey and Suzy turned out to be the most effective cultivars.
