The experiment aimed to estimate the influence of hydrogels used as components of the substrates upon the dynamics of rooting of the ‘Desio’ cultivar glasshouse carnation. Two hydrogels were used: Alcosorb-400, Akrygel-RP; at the doses of 2, 4, 6g/dm³, in following mixtures: peat+ bark (1:1), peat+perlite (1:1). The control substrates were those without any addition of hydrogels. The measurements and observations were carried out four times, 15, 20, 25 and 30 days after planting cuttings. Each time the measurements and observations concerned the estimation of mass and length of root system and overground parts of the plants. The analysis of dynamics of roots formation by cuttings showed that 20 days after planting one could easily see an advantageous influence of hydrogels doses which differentiated root mass and length later on. The largest dose of hydrogels (especially Alcosorb-400) contributed meaningfully to developing best formed root system by the cuttings, while the Akrygel-RP and growing doses of this superabsorbent influenced effectively the increase in mass and height of overground parts of the plant.

The experiment aimed to estimate the influence of hydrogels used as a component of the substrates on rooting the cuttings of glasshouse carnation. Two hydrogels were used: Alcosorb-400, Akrygel-RP at the doses of 2, 4, 6 g/dm³, in the following mixtures: bark, perlite, peat, peat+bark (1:1), peat+perlite (1:1), peat+bark+polyamide (1:1:1). The control substrates were those without any addition of hydrogels. The experiments proved a marked usefulness of hydrogels as the components of the substrates in rooting the cuttings of carnation. At all examined substrates the results were better after using the hydrogels. Increasing doses of hydrogels significantly affected the rise of the root mass of carnation cuttings ‘Desio’ cultivar. The best substrate for this cultivar was a mixture of peat with perlite (2.14 g) while the longest roots were obtained at using peat with bark (8.4 cm). In comparison to Akrygel-RP, the Alcosorb-400 affected the development of subterranean parts of the cuttings more adventageously. Applied doses of superabsorbents showed also the positive effect on growth of mass and height of above - ground parts of the cuttings.
