Dahlias are propagated through stem cuttings. In the years 2003–2005, in a glasshouse of the Experimental Station in Felin, University of Life Sciences in Lublin, the research was conducted to evaluate rooting of different types of dahlia cuttings. The studied Dahlia pinnata cultivars were: ‘Berliner Kleene’, ‘Gea’, ‘Orange’ and ‘Orietta’. Six types of cuttings were tested: cuttings with heel, without...
In modern greenhouse cultivations using the shoot bending method, the architecture of rose shrub is obtained by bending of primary stem, forming and suitable cutting of flower shoots and simultaneously bending of low-valuable stems. The studies performed in 2010–2012 indicated that the bending of stems of rose cv. ‘Red House’ increase the sprouting of high quality flower shoots, and parameters of...
Dahlia, together with chrysanthemums and tulips, is one of the most beautiful and the most willingly cultivated perennials in green areas and home gardens. Therefore, the producers seek for more effective methods of its propagation. In the years 2011–2014 in the Felin Experimental Farm of the University of Life Sciences in Lublin the research was undertaken to estimate the crowns efficiency of four...
Tulips belong to one of the most important bulbous plants from the economic point of view. Bulbs are reproduced in order to force for cut flowers. The biggest problem for the Polish producers is to obtain high yield of good quality bulbs, so that it is advisable to verify other than traditional methods of cultivation. The field experiment was conducted in 2006–2009. ‘Ballerina’ tulips were cultivated...
W artykule oceniono przydatność biomasy dwóch roślin krzewiastych do celów energetycznych - wierzby wiciowej i róży bezkolcowej uprawianych na poletkach doświadczalnych w KWK Bogdanka. Biomasa ocenianych krzewów energetycznych cechowała się porównywalnymi właściwościami energetycznymi, zaś różniła się: wielkością plonu, właściwościami fizycznymi, zawartością popiołu i składem pierwiastkowym. Salix...
In 1999–2001 years two Rosa × hybrida cultivars, ‘Casanova’ and ‘Korlingo’, were obtained by bud-grafting on a thornless multiflora rootstock (Rosa multiflora Thunb.). The first factor studied was the rootstock quality: class I (base diameter Ø= 4–6 mm); class II (base diameter Ø= 3–4 mm); class III (base diameter Ø= 2–3 mm). The second factor studied was the scion size: thick scions (Ø= 6–8 mm);...

Badania polowe prowadzono w latach 2006, 2007 i 2008. Materiał roślinny stanowiły bulwy mieczyka odmiany ‘Jessica’, które sadzono w plastikowych cylindrach w trzech pozycjach: piętką do dołu, bokiem i piętką do góry. Rośliny wykopywano partiami 9-krotnie w ciągu sezonu wegetacyjnego. W poszczególnych terminach pomiarów po wykopaniu roślin mierzono część nadziemną, masę roślin, masę bulw matecznych...
Badano wpływ BA+GA₃ na wzrost i kwitnienie Kohleria amabilis (PLANCHON & LINDEN) FRITSCH. W doświadczeniu wykorzystano rośliny wyprodukowane in vitro. Zastosowano mieszaninę BA i GA₃ dolistnie w stężeniach: 50; 100; 200 mg‧dm⁻³ oraz do podłoża w dawkach: 0,75; 1,5 i 3 mg‧doniczka⁻¹. Wykazano korzystny wpływ BA+GA₃ na cechy morfologiczne i fenologiczne kohlerii. Skuteczniejsze było BA+GA₃ aplikowane...
Badano wpływ fluropirimidolu na wzrost i rozwój Kohleria amabilis (PLANCHON & LINDEN) FRITSCH. W doświadczeniu wykorzystano rośliny wyprodukowane in vitro. Zastosowano retardant w formie dolistnej w stężeniach: 7,5; 15; 22,5; 30 mg‧dm⁻³ oraz doglebowej w dawkach: 0,1125; 0,225; 0,3375; 0,45 mg‧doniczka⁻¹. Wykazano, że fluropirimidol hamował wzrost kohlerii. Rośliny późno kwitły i późno osiągały...
The field study was carried out between 2000 and 2003. The plants of Sparaxis tricolor were sprayed twice prior to flowering with a fertilizer called titanium (0.8% Ti) in three concentrations: 0.02, 0.04 and 0.08%. Application of titanium in the concentration of 0.04% increases the total yield of corms by 20% on average and the commercial yield by 7%. Spraying the plants with titanium in the concentration...
