Influence of chemicals on the post-harvest quality of carnation cut-flowers.

Experiments were conducted to investigate the effect of flower preservatives alone and in combination with sucrose on the postharvest quality of cut flowers of carnation cultivars Acapalca and Pink Dona. CuSO4 at 0.1% and 0.2%, NaCl at 0.02% and 0.04%, citric acid at 0.0075 and 0.015%, calcium nitrate at 0.05 and 0.1%, STS [silver thiosulfate] at 0.5 and 1 mM and sucrose at 3 and 6% were used as vase solutions. Cumulative water uptake, transpirational water loss and fresh weight as well as vase life were significantly affected by the chemicals. Favourable results were obtained for ratio between cumulative water uptake and cumulative transpirational water loss and water balance. The treatment involving 1 mM STS recorded significantly higher values for cumulative water uptake (22.50 and 22.28 g/flower), cumulative fresh weight (19.50 and 21.20 g/flower) and vase life (15.75 and 16.25 days) in Acapalca and Pink Dona, respectively. Similarly, significantly higher cumulative water uptake (18.80 and 1 9.33 g/flower), cumulative fresh weight (18.50 and 21.30 g/flower) and vase life (18.67 and 19.67 days) were recorded in Acapalca and Pink Dona, respectively, when held in 1 mM STS+3% sucrose vase solution.
