Abstract

In the form of water solution through the soil in the rosette phase 2,4-Dhas been applied in four different concentrations: 2,0; 4,0 and 8,0 mg/l.Paralleled with those variants has been performed a control plant group treatedwith equally water volume. After 15, 30 and 45 day after hormone treatmenthave been taken the analyze samples. 2,4-D has been shown a stimulate effect onchloroplast pigments synthesis only after 45 days under 8,0 mg/l different after15 and 30 days when with increasing concentrations have been a inchibatedinfluence on chlorophyll as well as carotynoides synthesis. Fresh and dry massweight after 15 and 30 days at stem and leaves has been increased, while after45-ve days fresh and dry mass weight under 2,0 mg/l have been decreased thanat 4,0 and 8,0 mg/l whereas manifested a remarkable increasing
