Abstract
Dasada Blossom Company operates the cut flower business at Da Lat, Vietnam.
This highland location has plenty of natural ponds and ground water and this has led the company to apply groundwater (GW) in their company postharvest procedure.
This might cause some deterioration problem in their cut flowers by vascular blockage.
The study was aimed to extend vase life of Dendranthema grandiflora Celebrate by conducting an experiment in completely randomized design (CRD) with the application of aluminum sulfate (Al2(SO4)3) or Alum to improve the quality of GW before treatment with some chemical substance as vase solution: 1) groundwater (GW); 2) GW + 40 ppm of Alum; 3) GW + 150 ppm of citric acid + 5% of sucrose; and 4) GW + 40 ppm of Alum + 150 ppm of citric acid + 5% of sucrose, respectively.
The result showed that adding Alum into GW as vase solution decreased the pH level but increased EC. GW only accelerated flower blooming score in Celebrate plants, but shortened the vase life, while application of GW + Alum induced the highest rate of water uptake and delayed the decrease in initial FW. The most delay in flower blooming score was exhibited in GW + 40 ppm of Alum + 150 ppm of citric acid + 5% of sucrose.
It therefore represents a modified alternative method to improve GW quality before use as vase life solution in chrysanthemum cut flowers.
