The effect of silver thiosulphate and sucrose on the vase life of cut Sparaxis tricolor flowers was investigated. Ethylene release of by the flowers in six phases of their ontogeny was also determined. The Sparaxis tricolor species is characterized by short longevity of its flowers, amounting to 3-4 days. STS treatment did not prolong flower longevity. The application of sucrose solutions at a concentrations of 0.5%, 1%, 2%, and 4% increased the longevity only of those flowers which opened after the spikes were cut (the 2nd and 3rd flower), the increase not exceeding 1.5 days. The greatest amounts of ethylene were produced in the period preceding the flower drop.
