In general, the length of these straws is a few inches or less. Filters or valves are located at the points where the straws connect. These filters or valves can influence what passes from one straw to the next. Specifically, microorganisms, debris and air bubbles are restricted from moving through these filters or valves. Once flowers are harvested, inhibitors of water movement in xylem can reduce the flower life.
Air bubbles can form immediately upon cutting.
They also form later, as the flower loses water when being held dry. Dirt, debris and microbes can enter xylem tissue at any point in the marketing channel, simply from normal handling. Viviano Flower Shop Inc. All rights reserved.
