Floral Certification Practice Test

High humidity in the refrigeration of flowers plays a crucial role by minimizing water loss. Flowers naturally lose water through a process called transpiration, which can lead to wilting and a decrease in freshness. When humidity levels are elevated, the air surrounding the flowers contains more moisture, which reduces the rate of evaporation and helps flowers retain their water content. This is essential for maintaining hydration levels, ultimately extending the vase life and overall quality of the blooms. A well-hydrated flower is not only more visually appealing but also better equipped to withstand the stresses of handling and transportation.

Other options promote different outcomes that do not align with the effects of high humidity. For instance, increasing maturity rate or promoting flowering suggests changes in the natural growth cycle rather than the preservation of cut flowers. Encouraging microbial growth is typically undesirable, as high humidity can create a conducive environment for bacteria and fungi that can harm the flowers. Thus, minimizing water loss is the primary benefit of high humidity in floral refrigeration.
