  Keeping Cut Floers
  1 hile everybody enjoys fresh cut floers around their house, fe people kno ho to keep them for as long as possible. This may be done by keeping in mind a fe simple facts.
  2 An important thing to remember about cut floers is that they are sensitive to temperature. For example, studies have shon that cut carnations(康乃馨)retain their freshness eight times longer hen kept at 12℃ than hen kept at 26℃. Keeping freshly harvested floers at the right temperatures is probably the most important aspect of floer care.
  3 Floers are not intended by nature to live very long. Their biological purpose is simply to attract birds or insects, such as bees, for pollination(授粉). After that, they quickly dry up and die. The process by hich floers consume oxygen and produce carbon dioxide(二氧zxtf.net.cn化碳), called respiration(呼吸), generates the energy the floer needs to give the floer its shape and color. The making of seeds also depends on this energy. hile all living things respire, floers have a high level of respiration. A result of all this respiration is heat, and for floers the level of heat relative to the mass of the floer is very high. Respiration also brings about the eventual death of the floer. Thus the greater the level of respiration, the sooner the floer dies.
  4 Ho, then, to control the rate at hich floers die? By controlling respiration. Ho is respiration controlled? By controlling temperature. e kno that respiration produces heat, but the reverse is also true. Thus by maintaining lo temperatures, respiration is reduced and the cut floer ill age more sloly.
  5 Another vital factor in keeping cut floers is the quality of the ater in hich they are placed. Floers find it difficult to "drink" ater that is dirty or otherise polluted. Even hen ater looks and smells clean, it almost certainly contains harmful substances that can endanger the floers. To rid the ater of these unanted substances, household chlorine bleach(含氯漂白劑)can be used in small quantities. It is recommended that 15 drops of chlorine bleach(at 4% solution)be added to each liter of ater. The ater and solution should also be replaced each day.
