Freesias of Easy Pot group are very interesting complement to an assortment of flowering potted plants. However , there is a lack of information about their requirements and cultivation methods. Experiments were carried out in the years 2006–2007 in the unheated plastic tunnel. Cormlets of three cultivars: ‘Gompey’, ‘Popey’ and ‘Suzy’ were the plant material. Corms were soaked in solution of gibberellic acid in concentration of 10, 20, 40, 80 or 160 mg dm⁻³ for 24 hours just before planting, in a dark room with air temperature 28–30o C. Corms soaked in water were served as the control. During the vegetation season measurements of vegetative and generative traits of plants were conducted. After the end of vegetation period, coefficients of corm weight and number increase were calculated. It was found that cormlets of Easy Pot Freesia can be recommended for cultivation in pots. Cultivar had a significant effect on vegetative and generative parameters of plants. Among evaluated cultivars ‘Gompey’ was characterized by the greatest decorative value. Plants of this cultivar had the longest inflorescence shoots with the greatest number of lateral shoots and the greatest number of flowers. Irrespective of cultivar, gibberellic acid increased plant height, total number of leaves, length of inflorescence shoots and decreased flower diameter. The use of gibberellic acid increased weight of the offspring corms. Among evaluated concentrations the highest effect was noted for 160 mg dm⁻³. However, used in the experiment growth regulator did not affect number of obtained new corms.
Celem przeprowadzonych w latach 2006 i 2007 doświadczeń było określenie wpływu pięciu nawozów wieloskładnikowych (Azofoski, Plantacote Pluss 6M, Osmocote Plus 5-6M, Multivitu dwufazowego i Basacote Plus 6M) na kwitnienie i wartość dekoracyjną chryzantemy wielkokwiatowej odm. Galantino i odm. Pandora. Rośliny uprawiano w doniczkach, w podłożu torfowym, na poletku doświadczalnym. Nawozy wieloskładnikowe miały wpływ na kwitnienie i wartość dekoracyjną roślin. W obu latach badań chryzantemy odm. Galantino kwitły najobficiej i były najbardziej dekoracyjne, gdy rosły w podłożu z dodatkiem nawozu Plantacote Pluss 6M, a w 2006 roku - także, gdy zastosowano Multivit dwufazowy. Chryzantemy odm. Pandora miały w 2006 roku największą wartość dekoracyjną, gdy rosły w podłożach z dodatkiem nawozów Plantacote Pluss 6M i Multivit dwufazowy, a w drugim roku badań - kiedy zastosowano nawozy Plantacote Pluss 6M i Basacote Plus 6M.
The experiments were carried out in 2006-2007, in the spring-summer season, in an unheated plastic tunnel. Adventitious corms of Easy Pot Freesia: ‘Gompey’, ‘Popey’ and ‘Suzy’, were the plant material. The influence of a traditional fertilizer Azofoska and slow-release fertilizers, Osmocote Plus 5/6, Osmocote Exact and Polyon 5/6, on the ornamental value of plants was evaluated. All fertilizers were applied at rates of 2.5 and 5.0 g×dm-3. Freesias cultivated without fertilizer were the control plants. The cultivar ‘Gompey’ was characterized by longer inflorescence shoots and flowers of greater diameter, while the cultivar ‘Suzy’ had more flowers than the plants of the other cultivars evaluated. Plants with the greatest number of flowers and the longest inflorescences and shoots were obtained when slow-release fertilizers Osmocote Plus 5/6 and Osmocote Exact were used, regardless of cultivar and fertilizer dose. Polyon was useless for freesia fertilization, since it resulted in a decrease of the ornamental value of plants. Plants fertilized with Polyon had fewer flowers, additionally with a smaller diameter, and their inflorescences were shorter and deformed.
W latach 2006 i 2007 przeprowadzono dwa doświadczenia, w których zbadano wpływ pięciu nawozów wieloskładnikowych: Azofoski i czterech nawozów o działaniu spowolnionym: Plantacote Pluss 6M, Osmocote Plus 5-6M, Multivitu dwufazowego i Basacote Plus 6M, na wzrost dwóch odmian chryzantemy wielkokwiatowej: Galantino i Pandora. Chryzantemy posadzono do doniczek, jako podłoże stosując odkwaszony torf wysoki. Doniczki umieszczono w gruncie. Odmiany niejednakowo reagowały na zastosowane nawozy. Chryzantemy odm. Galantino były w obu latach badań najbardziej kształtne, proporcjonalne i wyrównane, gdy nawożono je nawozami Plantacote Pluss 6M oraz Multivitem dwufazowym, natomiast rośliny odm. Pandora - w pierwszym roku badań, kiedy zastosowano nawóz Plantacote Pluss 6M, a w drugim roku - gdy użyto nawozów Osmocote Exact 5-6M i Basacote Plus 6M. Wpływ nawozów na przebieg fazy wegetatywnej roślin w dużym stopniu zależał od warunków atmosferycznych panujących w czasie prowadzenia doświadczeń.

There is a great disarray in the taxonomy of genus Muscari. About 200 taxons are cultivated. Many plant names have their synonyms. The most often cultivated taxons are Muscari armeniacum and M. botryoides. Also M. aucheri and M. latifolium have become more popular. It is difficult to find information on growth, development and hardiness of grape hyacinths. In 2008−2009 in the Department of Ornamental Plants in West Pomeranian University of Technology in Szczecin a collection of taxons from genus Muscari was gathered. M. armeniacum and its cultivars: ‘Blue Spike’, ‘Cantab’, ‘Heavenly Blue’, ‘Atlantic’, ‘Blue Pearl’ and ‘Fantasy Creation’; M. aucheri and its cultivars ‘Blue Magic’, ‘Dark Eyes’, ‘Mount Hood’, ‘Sky Blue’ and ‘White Beauty’; M. azureum; M. botryoides; M. comosum; M. latifolium; M. macrocarpum; M. muscarimi; M. neglectum and M. ‘Valerie Finnis’ were collected and described in this article.
Ethylene is a plant hormone which play an important role in regulation of physiological plant processes. However, use of ethylene for practical purposes is restricted by its multilateral activity. Experiments were carried out in the years 2006–2007, in summer-autumn period to evaluate the influence of concentration of ethephon solution (125, 250, 500, 1000, 2000 mg dm⁻³) on growth, flowering, decorative value and yield of the offspring corms of three cultivars of Easy Pot Freesia: ‘Gompey’, ‘Popey’ and ‘Suzy’ grown from cormlets. Soaking corms in ethephon solution had an effect on the delay of germination and prolongation of vegetative phase. Corms soaked in ethephon solution of the highest concentrations, i.e. 1000 and 2000 mg dm⁻³ did not blossom. Regardless the cultivar the use of ethephon had an effect on the decrease of number of leaves set on main shoot and greenness index of leaves but also on the increase of number of shoots. The concentration 2000 mg dm⁻³ showed the strongest effect on the vegetative traits of plants. Ethephon affected also decorative value of freesia. The use of ethephon solution in concentrations of 125, 250 and 500 mg dm⁻³ had an effect on the decrease of length of main inflorescence shoot, and in concentrations of 125 and 250 mg dm⁻³ caused the increase of number of flowers in first inflorescence. Soaking corms in ethephon solution had an effect on the increase of coefficient of corm number increase but also on the decrease of coefficient of corm weight increase.
