Which of the following is NOT a factor affecting the quality of cut flowers?

Soil quality is not a factor affecting the quality of cut flowers once they have been harvested. Instead, soil quality is relevant during the growth phase of the plants, influencing how well the flowers develop while they are still growing in the ground. The factors that come into play after flowers have been cut include temperature, transpiration, and humidity, which all have direct effects on the longevity and appearance of cut flowers.

For instance, temperature can influence the rate of respiration and quality of cut flowers post-harvest, affecting their freshness. Transpiration refers to the process where water is lost through the leaves, and managing this is crucial for maintaining flower quality. Humidity plays a crucial role as well, affecting water loss and overall hydration of the flowers. These factors are therefore critical in determining how long the flowers will last after being cut and how they maintain their aesthetic appeal.
