SUCROSE PULSING AND COLD STORAGE ON POST-STORAGE ATTRIBUTES OF CUT LILY FLOWERS IN DALAT, VIETNAM

Lê Như Bích, Nguyễn Thị Hồng Nhung

Abstract


The effects of sucrose pulsing, cold storage methods (dry and wet) and cold storage duration (one and two weeks) on the post-storage attributes of cut lilies in Dalat were studied. After harvest, the lilies were treated with sucrose pulsing solutions consisting of three concentrations of sucrose (0, 50, and 100g/L) in combination with 0.2mM silver thiosulphate (STS) and water as control for 24h at room temperature, then placed in wet and dry cold storage at 2.5°C for one and two weeks. After each period of cold storage, the cut lilies were placed in water to evaluate the vase life, the time of bud opening, the bud opening rate, and water uptake. The results showed that when cut lilies were treated with 50g/L sucrose in combination with STS 0.2mM and one-week cold storage, the vase life increased to 16.8 days with better color, the time of bud opening slowed down to 5.8 days, buds fully opened (100%), and the water uptake remained constant at 91.5ml.
