Abstract
The effects on the cut flower production of three populations of Sandersonia tubers with different storage durations (lifted 1 May, 1 July and 1 September) were assessed over seven planting dates (between 1 September and 30 March). Stem length declined with planting dates from 1 September to 15 December, but increased with subsequent plantings.
Mean air temperature was greater in mid-summer and was the main cause of declining stem lengths in the September to December plantings.
Time from planting to harvest declined with later planting dates from September right through to late March, and was not significantly influenced by differing storage durations for a given planting date.
Carbohydrate concentrations in the tubers were analysed before and after storage; tuber sugar levels increased consistently during storage.
The reasons for these changes are discussed.
