ABSTRACT

The evaluation concerned usable parts of dill plants, cultivars Amat, Ambrozja, and Lukullus, grown in five cycles. The dill was sown on 10^th April, 10^th May, 10^th June, 10^th July, and 10^th August. Harvesting was carried out when the plants were 25 cm in height, i.e. within 36-45 days of sowing. The basic discriminants of the chemical composition were determined in leaves of dill alone and in those with petioles. Leaves of dill when compared with leaves with petioles contained far greater amounts of dry matter, total sugars, dietary fibre, and total and protein nitrogen, smaller differences concerning ash, titration acidity, reducing sugars, and starch. For five growing periods the compared cultivars showed on the average small differences in the level of analysed discriminants, a slightly higher level, however, being noted in the case of titration acidity, sugars, and dietary fibre in the cultivar Lukullus and of ash and starch in Amat

Key words: dill, harvest time, leaves, leaves with petioles, chemical composition.
