Sažetak
By the method of Steward and Shantz (1955) it has been attempted to determine the effect of 2,4-D and 2-NOXA (cone. 10~9 — 10~ 6) on the increase of the number of cells in explants of pumpkin. The cells were counted at the begining of the experiments on a sample (0), which was very similar to the explants under treatment and at the end of the experiments which lasted 25 days. For comparison countings on explants cultivated on the medium without addition of growth-stimulators were used.
The results obtained are shown in graphs by means of simple columns, 1 mm column height corresponding to 100,000 cells. It is evident that the cell number of explants, which grew on a medium with 2,4-D and 2-NOXA at higher concentrations (1Q~7 — 10~5) was larger in comparison to the control as well as to the explants grown at lower concentrations of the substances investigated.
