Efficacy of Germicides and Sucrose in Flower Foods

S.M.F. Dias, B.S. Reddy

Abstract


Four individual experiments were undertaken to assess the effect of four different biocides (citric acid, 8-Hydrogen quinoline sulphate,nickel chloride and cobalt sulphate) fortified with sucrose. Each biocide was tested individually as an individual experiment at optimum concentrations alone (0.25.0.5 &1mM concentrations) and in combination with sucrose at 2 and 4 per cent. From these 4 experiments, the 4 best treatments were selected (one best treatment from each experiment) indicating the optimum concentration of individual biocides alongwith the optimum concentration of sucrose. The treatments 0.5 mM acitric acid+4% sucrose;0.25mM8-Hydrogen quinoline sulphate+4% sucrose; 0.25mM nickel chloride +4% sucrose and 0.05mM cobalt sulhate +4% sucrose were found to be optimum. Observing the overall performance of the 4 individual experimetns it can be generalized that: all the above treatments have their advantages and disadvantages as the germicidal ingredient of the flower food formula; cut flowers performed best in germicidal solutions fortified with sucrose; fortification of flower food formula with 4 per cent sucrose proved to be more effective than 2 per cent sucrose. The cut roses held in the above treatments showed longer shelflife while flower opening/ blooming was in the desired direction.
