Wpływ podłoży z dodatkiem zeolitu oraz perlitu na ukorzenianie sadzonek pędowych Kolumnei szorstkiej (Columnea hirta Klotzsch et Hanst). Folia Pomer. Univ. Technol. Stetin., Agric., Aliment., Pisc., Zootech. 283 (17), 25–30.https://hdl.handle.net/20.500.12539/887The aim of the study conducted in the years 2008–2009 was assessment of the effect of growing media on rooting of apical and leaf-bud cuttings of hairy columnea (Columnea hirta). Medium components included sphagnum peat, perlite and zeolite in the following variants: 1. deacidified sphagnum peat, 2. zeolite, 3. peat with zeolite 3:1 v/v, 4. peat with zeolite 1:1 v/v, 5. peat with zeolite 1:3 v/v, 6. perlite, 7. peat with perlite 3:1 v/v, 8. peat with perlite 1:1 v/v, 9. peat with perlite 1:3 v/v. After 6 weeks of rooting, the number of developed roots and their length, the number of roots longer than 3 cm, and also the number of offshoots developed by cuttings. Apical cuttings developed larger and more complicated root system than leaf-bud cuttings. The plants that were rooted in media with the addition of zeolite or perlite (25–50%) produced many roots. The number of long roots were the biggest in the medium peat + zeolite 3:1 v/v.plUznanie autorstwa-Użycie niekomercyjne 3.0 PolskaColumneaperlitsadzonkaukorzenianiezeolitColumneacuttingmediumperliterootingzeolitepodłożeDyscyplina::Nauki rolnicze::rolnictwo i ogrodnictwoArticle2300-5378
