| Abstract: | The distribution and persistence of chlormequat was determined chemically in chlormequat treated potato plants and in the progeny from their tubers. Chlormequat penetrated into the leaves, was translocated to the tubers and accumulated in the underground parts. Potato tubers harvested from chlormequattreated plants produced temporarily dwarfed plants. In the progeny of tubers, the compound was translocated to all parts of the plant, the highest amounts being found in the underground parts. A loss of only 18 ± 2% occurred between planting the seed tubers and harvesting the potato plants 2 months later. |
