| Popis: | Tubers of Zantedeschia elliottiana (Watson) Engl. and the hybrid Z. ‘Pink Satin’, a Z. rehmannii Engl.-like selection, were stored at 5°C. Over a 3-month period they were transferred to incubators at 12°, 18°, or 24° for 2, 4, 6, 8, or 12 weeks of holding. One-third of these tubers were planted in moist media during this time; the remaining tubers were stored dry and on removal were sprayed with either gibberellic acid (GA3) at 50 mg·liter−1 or distilled water before planting and transfer to a greenhouse. The proportion of flowering of dry-stored tubers of Z. elliottiana was reduced by prolonged storage at 5°. Subsequent storage at 12° did not reduce this proportion, but, at 18° and 24° flowering was reduced further. Tubers of Z. ‘Pink Satin’ were less sensitive to the duration of dry storage at 5°, but increasing time of storage at all subsequent temperatures caused a progressive decrease in the proportion of tubers that flowered. The proportion of moist-stored tubers of both selections that flowered was greater than that for tubers stored dry for an equivalent time. A preplant treatment with GA3 enabled almost total compensation for reduced flowering except after the longest period of storage. |
