Abstract Temperatures of 3-5deg.C were suitable for the
long-term storage of sandersonia tubers. Tubers sprouted during storage at
10deg.C, but no sprouting occurred with up to 202 days of storage at 3-5deg.C.
Tuber viability and subsequent sprouting were less after storage at 1deg.C than
following 3-5deg.C storage temperatures. Sprouting temperatures of 20-26deg.C
gave high sprouting percentages following long-term storage. Tubers failed to
sprout at 35deg.C and sprouting percentages were lower at 30deg.C than
20-25deg.C following longer storage durations (>60 days). Storage duration,
storage temperatures, and sprouting temperatures influenced the time from
storage removal to sprouting, storage removal to stem harvest, stem size, and
daughter tuber weight. Stem length declined with increasing storage duration of
110-171 days, but was slightly greater after 202 days of storage than after 171
days. Possible reasons for these plant responses are outlined. Daughter tuber
weight declined with storage duration and was less following a sprouting
temperature of 20deg.C than 23-26deg.C.
