SUMMARY This study was out at the Postharvest Section of Atatürk Central Horticultural Research Instıtute in 1995 and 1996. The Possibility of extending the longevity of ethylene sensitive flowers (Carnations, Fressia, Lillium, Alstroemeria and Gypsophila) were investigated by different pulse treatments with STS (silver thiosulphate), AOA (aminooxyacetic acid), AIB (aminoisobutyric acid) GA3 (gibberellic acid), kinetin, Triton X-100, HQC (hydroxyquinoline citrate) and sucrose. In addition, some treatments were continuously given to the flowers in vase solution. As a result,for carnations, a pulse treatment mixture of AOA (500mg/l), Triton X-100 (500mg/l) and kinetin (10mg/l) was found to have similar effect to STS that is alternative to STS pulsing was found for the other 4 species (Fressia, Lillium, Alstroemeria and Gypsophila). Sucrose treatment had effect on the longevity of Fressia and Gypsophila. The bud opening of Fressia flowers cut tight bud stage was promoted by a pulse treatment for 24 h with 20% sucrose and 200 mg/l 8-HQC. A pulse treatment with 15% sucrose and 200mg/l HQC promoted bud opening and increased vase life of Gypsophila flowers. GA3 and kinetin in vase solution of Alstroemeria flowers had no significant effect on longevity. |
