In a previous study, a formulation composed of glucose, isothiazolinonic germicide, citric acid, and aluminum sulphate (GLCA) extended the vase life of cut rose flowers. In the present study, we investigated the effect of GLCA on the vase life of cut 'Rote Rose' rose flowers under various conditions. Application of GLCA markedly extended the vase life of flowers held at a high temperature (30 deg C). GLCA treatment also extended the vase life of flowers harvested earlier than the usual harvesting stage. To examine whether GLCA extended vase life under more typical conditions, we stored cut rose flowers at 10 deg C overnight, then maintained them at 8 deg C for 3 days. We then held them at 28 deg C and began treatment with GLCA. The vase life of these flowers was markedly extended by GLCA treatment. When cut rose flowers were pre-treated with GLCA for 4 days as a preservative for growers, vase life was not significantly extended, but this treatment increased flower diameter and inhibited the problem of bent neck.
