Flowers

Hi, I’m a High School Student.
I’m doing research and experiment on this topic.
How do they keep their flowers fresh, so they last longer? What substance/chemical do they spray/soak in it? How do they deal with the senessence thing? And I heard they cut it or something at someplaces… where is that and how? Does it work on any flowers?

If I were to do the experiment, what type of flowers should I use?

Not all questions above had to be answered, and any suggestions would be fine too. I just need infromation now.

Thanks =]

There are many ways.

-keep them cool
-keep the water clean
-keep the stems in the correct nutrient water
-keep the stems clean
-reduce evaporation from leaves etc

Substances can also be used to block senescence receptors – don’t quote me, but I think a silver (Ag) compound might be one such substance.

   Ok don’t take this as gospel as I haven’t done this for a while, but as a part of a plant is removed from its parent gradually senesces (sic) meaning it begins to die as nutrition is not being delivered from the root system.
   As this part begins to die, bacteria and viruses can enter from the cut area and speed up its demise.
   One ‘old wives tale’ I found to slow down their freshness is to use an antibacterial/antiviral in the water such as bleach. A couple of drops in the storage water saves them a bit longer.
