WHat materails keep flowers fresh after picked?

my freind and I are doing a science experiment and we need ideas

WHat materails keep flowers fresh after picked?
Here are a few ideas that you might try. Most have been tried and thought to help in keeping cut flowers fresher longer.


Use a sharp knife or shears to cut stems on a slant under running water. Cutting them straight across tends to block absorption of water.


A penny and an aspirin tablet placed in the vase water keep flowers fresh longer. The theory is that the copper acts a fungicide and the aspirin makes the water more acidic. Here are more food + acid combinations:


Add one part lemon-lime soda (not diet) to 3 parts water. Then to each quart of this solution, add 1/4 teaspoon bleach. Thereafter, add 1/4 teaspoon bleach after each 4 days of use.


To 1 quart water add 2 tablespoons fresh lemon juice, 1 tablespoon sugar, and 1/2 teaspoon bleach.


Add 2 ounces Listerine mouthwash per gallon of water. Listerine contains sucrose (food) and a bactericide. Listerine is acidic and is said help water move up the stems.


Remember that whatever the methods you use you must have a control trial to compare to.

Reply:Some people just put their freshly picked flowers in a vase with water. But since you're doing a science experiment, I suggest you use abscisic acid. This is a plant hormone which inhibits gowth and promotes dormancy. This will prevent the buds from blooming fast or the opened flowers to die quick.





Hope i did help ^^,
Reply:adding a pinch of sugar to the water helps, as does putting a copper coin into the vase (copper helps inhibit the growth of mould and bacteria). also, keep flowers away from fruit (ripe fruit releases the gas ethylene which will cause the flowers to age and wilt faster).
