| When germination beds of carrot seeds were treated with either 0.01M or 0.05M concentrations of Ca(NO3)2, CaSO4, MgSO4, K2SO4 and KH2PO4, an acceleration in the germination rate was observed in the groups treated with 0.01M KH2PO4 and 0.05M MgSO4 and 0.05M Ca(NO2)3. In earlier work by the author with acetone a similar result was observed and reported. The pH range in these experiments was maintained between 5.0 and 6.0. It was found that the groups treated with 0.05M K2SO4, 0.05M Ca(NO3)2, 0.05M Ca(NO3)2, 0.05M MgSO4, 0.01M KH2PO4, 0.01M Ca(NO3)2 germinated earlier than the control group. The acceleration of the germintion rate varied with the inorganic compounds used in the following descending order; 0.01M KH2PO4, 0.05M Ca(NO3)2, 0.05M K2SO4, 0.05M CaSO4 and 0.05M KH2PO4. As a result of these expriments, it occurs to the author that in the germination of carrot seeds some inorganic compounds appear to activate the osmotic function of carrot seeds causing acceleration in the germination rate. |
