| Abstract: | Summary In three experiments seed tubers of cvs Jaerla, Bintje and Alpha, stored at 12 °C in the dark, were planted in glasshouses
on various dates at soil temperatures varying from 8 °C to 28 °C to study the phenomenon of ‘non-emergence’ with ageing seed
tubers. In general the tubers were desprouted before planting. At all plantings cv. Alpha produced normal plants. The cvs
Jaerla and Bintje, however, showed high proportions of the ‘little potato’ phenomenon when planted in cold soil, and high
proportions of decayed tubers more frequently in warm soil. When using physiologically older seed at later planting dates,
both the range of soil temperatures became wider and the proportions of seed tubers experiencing both ‘little potato’ and
decay increased. |
