CARROT SEED PREPARATION IN A CORONA DISCHARGE FIELD

The influence of a corona discharge field to the quality of carrot seed (its germinating power and the separation of biologically viable seed) is discussed. The seeds were processed with a cylindrical electric separator. Several methods of the intensification of the germinating power were compared when discussing the influence of a corona discharge field to the germinating power: control seed unaffected by soaking or discharge; seed soaked in ordinary water for 24 h; seed soaked in ordinary water for 24 h and germinated by constantly wetting it; seed soaked in alkaline activated water with 11.65 pH for 24 h and seed stimulated by a corona discharge field. Two methods were chosen for the comparison of the results of the seed separation: corona discharge field in the cylindrical separator separated the seeds into 4 fractions; seeds were sorted in the 5 % solution of NaCl into 2 fractions. The tests showed that stimulating carrot seed with corona discharge fields increases germination from 7 % to 19%; grading of seed material by a corona discharge field in cylinder separator enables to distinguish 60 % of seed whose quality indicators are better than those of the control
