Microbial and especially Bacterial growth in holding solutions of cut flowers can cause blockage in the xylem and later will result to impair water uptake and faster wilting.
In this experiment, after harvesting and transporting the cut orchid flowers to the Lab, they were put in the bottles containing distilled water which was treated with 0, 1.3, 2.6, 3.9, and 5.2 mg/L aqueous ozone and during 24 hrs each 6 hours, bottles solutions were sampled and cultured in different media and the predominant bacterial type was determined.
Results revealed: the sequence of the strain of studied bacteria is 88, 87, and 86%sequence similar to the sequence of the strains Burkholderia cenocepaciaandBurkholderia dolosa. Moreover, aqueous ozone at 1.3 and 2.6 mg/L did not significantly decrease bacteria population compared to distilled water, while at 3.9 and 5.2 mg/L, the populations were significantly (P≤0.01) reduced.
