Növényi Növekedés-Szabályzók Hatása Egynyári Dísznövényekre

Leghatásosabb szernek a Regalis és a Caramba bizonyult, az eredmények függvényében. Legjobb kísérleti taxon pedig a Matthiola incana volt. A többi kísérletbe vont taxon is reagált a kezelésekre, de nem annyira kimagaslóan, mint a Matthiola incana esetében. A virágzási intervallumok a legtöbb esetben lerövidültek, de nem olyan mértékben, ami nagyban ronthatná a piacképességét. A virágszám nőtt, a bokros habitus szintén. Több esetben megfigyelhetők voltak levéldeformációk. A kísérlet és a használt szerek alkalmasak további kísérletek folytatására. -------------------------------------------------------- To reach the habits for market purpose we used alternative biostimulators and retardants such as Regalis, Toprex, Caramba, CCC and Cultar. These are mainly fungicides but have dwarf-growth influencing effect. The species used for the experiment were Coreopsis grandiflora, Godetia grandifolra, Scabiosa atropurpurea, Matthiola incana and Schizanthus wisentonensis. The trial interval was 2010 April to 2011 July. The treatments were started when the plants were in 2-3 true leaf stage. From that time the treatments were repeated in 14-18 days cycle with the substances. We tried to increase the habit, the intensity of blooming and durability with conditioning substances.The results were followed-up by biochemical and histological methods too. Summarizing, all chemicals had effect on the tested species. Regalis and Cultar showed the most effective achievement. With these substances treated plants have more, shorter joints, more and robust leafs, and more compact habit comparing to the kontroll plants. Regarding blooming the treated plants started to bloom 10-14 days later, and 15 % of the treated Scabiosa atropurpurea pots haven’t started blooming during the vegetation interval time. Matthiola incana showed very good results, it was a successful trial plant.
