| Abstract: | Summary The formation of above-ground tubers on stem cuttings of eight potato cultivars was studied over three seasons. To promote
tuber formation in the leaf axils, stems grown from single node cuttings were exposed to short day conditions. Tuber formation
underground was reduced by covering the soil with a plastic sheet and by using single node cuttings planted with the leaf
axils several centimetres above the soil surface. With all cultivars except Alpha, which produced mis-shapen tubers in all
experiments, an average of 11 (maximum 40) tubers per cutting were harvested. Significant cultivar × year interactions were
observed. |
