The Effect of Growth Retardants on Annual and Perennial Potplants
AbstractThere are more chemicals in circulation that have a dwarf-growth influence for the plants (Basra, 2000; Korting, 2010; Reiners, 2007; Richter, 2006; Ueber, 2007). Among these substrates we took into the trial five chemicals: CCC, Caramba, Cultar, Regalis and Toprex. These substrates were accommodated in concentration by the reference of the producer. Examined species were: In this preliminary experiment the reaction of the species was observed. We measured the height of the plants, the number of lateral branches, the diameter of the plant bush and the size of leaves. The unfavourable effects (necrosis) were also detected. The trial was started on 19. April, 2010. The seeds were sown into seedflats, and were put into a greenhouse in Mátrafüred. The seeds sprouted within 14-16 days. When the plants reached the 2 leaf stage they were transplanted into pots on 5. May 2010. At first, 6 groups of plants were composed, 5 chemicals in the trial and a control group. By Matthiola incana, Coreopsis grandiflora and Scabiosa atropurpurea 25 pots consisted of a group, while by Godetia grandiflora 15 pots, as germinating of Godetia was just about 60%. Treating data were: 11th May 2010, 27th May 2010, 17th June 2010. All the chemicals showed adequate results except Caramba. By this substrate we found burned leafs. So a new concentration of Caramba was made.
